ya i already have the d44 rear because mine was a 4+3 right? i also have talked to tom of prostreet and plan on buying the cbeam adapter in the next few days. ill just have to get my driveshaft cut down a inch or so right. thanks

Wrong. The 84 came with a D36 whether auto or manual. The D44 driveshaft and c-beam are an inch shorter.
Then again, even if I got sick of the T5 I'm not sure if I'd use the ZF's pull style clutch setup. I'd probably be on the phone with LD85 on how to make the hydraulic TOB work. -- Joe |

This swap is very cost effective if you have an '84 manual car, or an automatic car and want a stick. For folks with D44's the cost of shortening the driveshaft might be prohibitive. I had a budget I went with for swapping my 700R4 to a manual transmission. Budget was about $1200 total, for everything I needed. If I had to spend another $250 shortening a driveshaft, it would lend more to the case of just going with a ZF trans. If someone is willing to shorten a driveshaft for less than $100, than it's a different story. Everyone I called around here wanted $250+ because it's aluminum. Luckily my rear is D36.

What Joe's saying is, with the longer T5, you need to shorten the beam. Just happens that D36 cars can simply bolt-in the shorter D44 beam. D44 cars though don't have anything shorter to put in so they have to modify their beam. |
This is a great thread and since I have a 4+3, I am watching with great interest. Many thanks to the pioneers that are keep us posted on the results.
I have two questions: First, if it is going to cost over $250 to get a driveshaft shortened, was there a way to get the standard length one in, before the C-Beam is bolted up? That might be a pain, but for $250 it might be manageable...... Second, with regards to the modification of the shifter, is this necessary in order to make it come up in the stock location? Would it be possible to just modify the console, or would that put the shifter too far over to the right? I am thinking it might be easier to make a plate to go over the top of the console and leave the shifter in the middle. thanks again |

thanks again Personally, i'd rather have my shifter in the stock location. I understand the trade off as pointed out by CC. I just noticed you are from Mass. I invite you to come visit my shop any time you'd like to take a look at things first hand. Once the car is finished you can take it for a spin as well. -- Joe |

You bet, it will come up in the dead center, with a bias to the front. You still need to make the shifter straight, either by heating it up or cutting and rewelding it OR use a mustang shifter. If you use a mustang shifter it will come up in the dead center. This is how pro-street does their conversions, they actually make a plate that will go into the center console.

ok since i have a d36 can i just get my driveshaft shortened or do i have to buy a d44 driveshaft.

When it comes straight up, is it too far forward, I mean will you be hitting your knuckles on the radio knobs? If that is the case and the shifter needs to be modified anyway, then it may be easier to use the stock location.
I would love to come and check out your shop, maybe on a nice day, you can pick me up at the airport. The shifter is tilted so the stick wouldn't come too close to the radio, but would still be far forward for us guys who sit way back. -- Joe |

Buying one should be cheaper though. Or even just install the one you have before lifting the trans in place. |
I've been working on the plow truck lately but I took 20 minutes today to finish the shifter. The magic number ended up being 2" back, and 3" to the left, with a 20* angle. I'll take some pix this week.
The shifter base hits the cup holder bottoms BTW, which may not be acceptable fro some folks. A mustang shifter might give a little more clearance, but the cup holder (forward one) is going to need to be trimmed out of the shifter plate to make this work. The shifter "rise" isn't really that noticeable. It's almost done. I gotta button up a few things but overall the swap is doable. I'm gonna re-word some of the how-to with the disclaimers (i.e, things you'll have to live with). -- Joe |

thanks for all your effort and sharing on this. I have another shifter concern, and thats the height of the stick. I feel like it's too tall, but don't have another vette to compare it to. Anyone got a pic of their interior for comparison? -- Joe |

Not sure if this is close enough for you to get anything from, but the shifter is in neutral and the top of the shifter is about at the bottom of the radio opening. I'd be happy to get some closer shots or even take some measurements if you'd like. This is the stock 4+3 shifter. http://www.corvetteforum.net/c4/rayq...s/interior.jpg |

Thank you! -- Joe |
Joe,
My 4+3 always felt too high with the stock stick. I think it's mainly the seating position, the console is so high to start with. Is the McLeod shifter adjustable for height? Is it shorter than yours? BTW, what other problems have you run into? You said you were posting some more "things to live with" |
interesting thread.....I will put TKO 500 Tremec Keisler, just so I can find it in a search in the future.

ok i have some questions, first off i bought the cbeam adapter 2 days ago also i have found a transmission i was wondering if anyone has a d44 driveshaft for sale on here also wht will have to be done to make this shifter work, the clutch and the bellhousing are the same as the 4+3 correct. what else do i have to worry about on this swap. thanks

If you can weld, get a mustand shifter and modify it to the specs in my swap howto. If you cannot weld you'll have to get someone to weld it for you. Clutch and BH are the same, yes. -- Joe |

thanx! Might want to drop Central coaster a PM though. A lot of my initial ZF vs 4+3 knowledge was from the FAQ and posts on here, which have turned out to be pretty bogus information. I've driven a few ZF cars and only had one apart for a clutch job back in 2003. -- Joe |
true true
spent many sunday afternoons swapping T5's in and out of my camaros after grenading them this should be a relatively easy swap from the looks of it |
Hello,
Can anyone tell me the proper shifter position (length of transmission from front of bellhousing to center of shifter) for early C4's? Does anyone have a 4+3 out of the car they can measure? I am considering an alternative transmission for a swap. |
Ben,
Wouldn't it be the same as the ZF-6? Shifters come up in same position. I didn't modify anything when I did swap on my 84. |

I have searched and searched without any luck.... I am considering a R154 (supra turbo) transmission as they are readily available here. I have a friend who has used one behind a LT5 for 4 or 5 years without any issues. If the shifter position is ok, I will investigate further. Bellhousing and clutch are readily available. |
If the Supra trans works behind an LT5, its using a deeper BH and consequently a longer input shaft than the one for an SBC. I think the diff is about 1.25". Someone else could verify.
Good to hear from you again. How's the 383 running? |

Good to hear from you again. How's the 383 running? The supra-LT5 BH was a one off.. The supra-SBC BH's are available off the shelf here from at least 3 manufacturers that I know of. Its been done a thousand times in other cars with small chevy's. I have barely driven my car in the last year.. Work, baby and life in general... you know :) I'll be back into it soon though. I have a pile of parts to go in, and I have a lift also now, so that makes it all the more enjoyable to work on too! |

The car was a 4+3 to start it has a 700R4 raptor setup in it now that was put in for drag racing and a valve body setup went bad and blew the clutch packs in it. The car still has the clutch pedal and slave for the 4+3..IN fact I have to put the clutch down to start it still. I picked up a ZR1 zf6 speed for a very good price but I have no bellhousing or clutch. I want to put this in the car. What do I need? was the drive shaft changed for the 700R4? Do I need a new one for the ZF or since it was a 4+3 does it line up? what other parts do I need?
The ZR-1 ZF has a longer input shaft. Won't fit right on an SBC. :( |

ZF6 swap
OK well.. I dont get it. Dont people put the zf6 with the standared L-98 motor all the time, The L-98 also comes with a 700r4. and I have one in my car now with the zz4?. and the car That the ZR1 transmission came out of was a show car with a 502 create motor. ITs a black tag transmission. IS there any way i can put this tranny to my ZZ4? And if so do you think the drive shaft was changed for the 4+3 to 700R4 swap that was done or is it the same?

Either that or replace the input shaft. :sadangel: |

Just because its a black tag doesn't make it a ZR-1 ZF. A ZR-1 trans can be used on a small block, but the shifter is going to be 1" further. GM used the longer input shaft for the ZR because the ZR motor was 1" shorter than the standard SBC. The bellhousing for a ZR-1 is also longer for the spacing. So there are 2 versions of the ZF-6 for the C4. You need the version for the regular 89-96 C4s, not the ZR-1. I put a black tag in my 84 so I have some experience with this.
Either that or replace the input shaft. :sadangel: |
Phat,
Go to this website, www.zfdoc.com. Bill Boudreau is very good and very helpful. He knows ZFs like the back of his hand and should be able to give you the info you need. |

a little warning....
I love the robust nature of this swap , I really do. Its exciting to see a group of people all chip in and try to make something work. As most know here I've rebuilt the 4+3 for years, sold parts to GM for these, was a rebuilder for GM and dealerships many years and sold my tooling and hard parts to Brian of SK speed years ago.
The warning is the following: The 4+3 transmission assembly was prone to cracking the mid section bearing plate on the bottom due to case flex imparted by loads of the C-Beam. Not to burst anyone's bubble here, but you should be concerned about the loads you are expecting these very thin T5 tails to take. What I would worry about is the shift rail binding due to flex as well as the rear bushing wiping out due to case flex. You may want to secure the mount pad to something else to make your flex path shorter. Don't forget that Camaro T5 had a mount to the frame having the T5 float on the back could be a potential problem. Most of the time when that gimmick is tried out you will find the upper ears where the tail attaches to the case snap. Carry on. Paul www.5speeds.com |
Paul,
Very interesting. And you bring up some great points. So I would imagine that the ZF was built with those issues taken into consideration. Correct? |

I'd be similarly curious to know if Keisler beefed up the tailshaft of their TKO swap. They rate the tranny at 500+ hp and I know there are guys on this board who thrash theirs pretty hard. The tailshaft appears to be stock TKO with an offset shifter. In fact, the bolt-on cover the TKO tailshaft has ought to make it rather weak in that area.
Atleast the T5 was designed, in some aspect, to have a mount at the tailshaft. In a Camaro, the T5 tailshaft mount takes much the same twisting force as in the C4. In my car, which will soon have a T5, I have poly engine mounts and poly diff bushings. The amount of twist should be atleast somewhat limited in this respect. I would think the force required to twist and deform the T5 tailshaft would first break my D36 rear. I suppose time will tell... |

the Cbeam adapter pro street made (as you now know) bolts up in numerous spots, rather than loading just the very tail of the transmission. I think it should be fine. If you have enough power to brake T5 cases, then do one of the following: 1) Buy a few spare tail shafts 2) Consider a different transmission. Thats my 2 cents on that issue.

Well, you are one of the trans experts 'round here Joe. I do have the power to destroy a T5 in my car (383 @ ~425 horses). Thing is, I don't race (can't afford the broken parts) and I figure as long as I keep street tires on the car I'll break traction long before I break a tranny. Not really worried either. I am curious, though, what twisted enough to allow you to break a T5 mount (soft motor mounts, driveshaft bottoming out in the yoke, etc?).

I wish I dynoed my 355 before I stripped the car. Thing trapped 119-120mph every pass in the 1/4, with 1.60-1.70 60 foot times. 3650 lbs with me in it. That HAD to be near 500hp. Never broke a T5 racing it. Anyhow, the thirdgen rear end has two lower control arms on the bottom, two coil springs, a panhard bar and a torque arm. The torque arm is the only thing that keeps the rear end from rotating since there is no upper control arms. It's like a third member, or a 3-link. hah. Anyway, when you give it gas, the arm pushes up on the transmission; when you downshift, the rear end attempts to rotate downward and pulls on the tailshaft. So if you hit it hard enough, the torque arm will lift on the transmission ripping the mount in two, and the transmission then hits the floor and scares the crap out of the driver if it's the first time. The torque arm is not bolted directly to the tailshaft, instead a torque arm mount is bolted to the tailshaft, and the torque arm fits through a rubber coupling in the mount. This allows the torque arm to move a little with the suspension travel (since its a live axle, not fixed like a C4). -- Joe |
I get it. So, in a way, the C4 might actually be a bit less stressful on a T5 tailshaft than an FBody?

There is no float in this application, and unlike the Camaro it must be locked solid. I'm am not saying it won't work, but its just a point to consider. |
Interesting point Paul (5Speeds). I'm glad that you added to this thread.
I wonder if a strut rod(s) would be of any benifit? (Similar to struts found on 4WD transfer case to transmission assemblies). 'Not sure where to mount them though, where it would actually help take some of the torsional stress. |
Years ago on the S-10 T5's there was a lower fin on the tail that reinforcement straps bolted to that "V"'d out into the bell. The idea was to keep the assembly from twisting. Something like this may help, but the cracking problem existed on the factory 4+3 anyway. People always thought it was just a bolt leaking on the bottom of the case mid section, but actually the case would crack at that point and oil would like around the gasket and out of the crack.
Any one who has a gear lube leak at where the OD unit meets the adapter basically has a cracked section. |

Hmmm, that ma actually explain my current gear oil leak in my 4+3. It's leakin' out somewhere, and I think it's between the sections. Is the 4-speed part cracked or the OD part? OD still works...
|
Tak some brake cleaner and clean up the mid section casting. Its usually dead enter on the bottom. The casting is thin there and cracks from flex..
The fix is simple actually. When I use to rebuild those units, there are 2 12 point bolts that fasten the adapter housing to the 4 speed ( inside). The gasket basically seals the upper portion of the lower hole, but doesn't surround the complete bolt hole. So when it cracks the oil goes into the hole and out the bottom. What I did was after every 4 speed rebuild was fill the hole with epoxy BEFORE bolting on the OD, so in the event it ever did crack the oil could never leak out. You would need to pull the trans, remove the OD and seal the hole and of course use a new gasket. |
With a little imagination, you can do just about anything.
I ended up installing a Jerico 4-sp box (race prepped T-10 top loader) in my C4. It weighs just over 60#. It has straight cut gears for clutchless shifting. You can stack your gears in multiple ratio's. Good to 800 ft/lbs torque. |
Hey just bought my t-5 and also I bought the adapter a little while ago so soon ill be able to get started

I thought it was a little high, until I got the ZF6. Seems as if GM designed these to shift like dump trucks. -- Joe |
Nah, I haven't finished cutting the side out of the console yet (the part still attached to the car, not the shifter cover part). I'm gonna snap pics of the shifter and the patching when I get back on track so you can add pics of a 4+3 tunnel to your writeup. It's different than the auto tunnel.
The dealer is supposedly getting me the T5 part I lost, but it won't be here til late this week (which means probably next week). Ah, well, that'll teach me. You might wanna add a pic of the oiler thingy to your writeup and tell people to make sure they look after it ;) Hey Joe, been meaning to ask, I picked up a "Spectre" rubber boot (cheap chinese copy of a hurst boot). The large one. The trans sits off to one side of the hole I've made in the tunnel. I should center the boot over where the stick actually sits when in neutral, not over the center of the trans, right? Otherwise the boot will always be cocked way to the left and might make the sifter hard to hit 1st in. Still gotta find me a 'Stang lever and ball. No junkyards around here got one. What year/model am I looking for? |

Nah, I haven't finished cutting the side out of the console yet (the part still attached to the car, not the shifter cover part). I'm gonna snap pics of the shifter and the patching when I get back on track so you can add pics of a 4+3 tunnel to your writeup. It's different than the auto tunnel.
The dealer is supposedly getting me the T5 part I lost, but it won't be here til late this week (which means probably next week). Ah, well, that'll teach me.

4+3 swap
how does the speedometer connect if you swap a 4+3 to 5 or 6 speed?

I guess you could probably use an electronic VSS from any thirdgen fbody, if you swap the connector. -- Joe |

Should have called me up! I have every part for most T5 transmissions....

I got it and got it back in. All is well. THe car is moving, but I haven't road-tested it truly yet. I posted pics in a new thread.

They make a bracket for the T-5 7 t-56
They make a bracket for the T-5 & T-56.
I can't remember who makes it. |

As far as the pro-street bracket goes, it's only been available for a few months. I have had some emails off site from non-members who have done it, but we're still talking only 2-3 months tops. -- Joe |
Ok will do. Thanks Joe.

:bump: anyone have a road test report of a T5 swap?
I'm still collecting parts for my swap. |

Sadly I've still not gotten my exhaust squared away enough for a road test. Work and such, y'all know how it gets sometimes...

Theres 1 or 2 guys who made their own bracket. If you search, you'll find one of them still posts here. Hes got a couple years of use out of it.

Ive had Pro Streets t-56 conversion in my 86 for over two years now and couldnt be happier. Ive got alot of hsp and have not been gentle on the car and its just as solid as the day that I installed it. As far as the t-56 goes I havent ever heard of anyone blowing one ,thats the reason that I chose it over the zf-6,-- + too many syncro problems and to expensive to rebuild.:cheers:
I agree with the ZF6 stuff. The ZF6 was also more of a PITA to install on my car, required more cuttings and more expensive parts, the clearances all the way up to the stupid starter are absolutely insane. AND they shift goofy. -- Joe |
Joe, have you completed your ZF6 swap using 4+3 hydraulics? How does it feel? You gonna do a T56 next?

Then the starter bit me. If the block is like a few thousands different than a production LT1, the starter is a PITA to bolt up. My ZF6 swap ended up costing about $1800. Stick with the T5... I'm gonna run it until it explodes. When it does I'll push it in the river and buy a C5.. -- Joe |
They make a kit for the T5
Last week a guy posted a web site prostreetcustoms.net
They make a kit for the C4 T-56 & the T-5 Transmissions. I would go with the T-56 / 6 speed myself Also, I went to the web site to look at their Truss Bar. Iam going to order one next week. I talked to the the owner Tom and he said the he has enough stock to make 23 bars and he's going to stop making them. He say's It's getting harder to have the rear locators made. GM stop making them. So if you want to buy one, you better order it soon. :cheers: |

It was a bit more work than I expected, but not that bad and I got the whole thing done for less than $500.
And I'm not talking crap either, I've done the T5 AND the ZF6 swap. The ZF6 swap is a pita and it costs way more, 6th us useless as you suggested without a rear-end swap, etc. Don't listen to the "bogus" guys on 'the other site'. Half of them don't do their own mechanical work.. -- Joe |
hey I have the t-5 in the car now didnt do the shifter yet, but have been taking it out a few times without the boot and center piece in, WOW this car is so much more fun hits second way harder than it used to, way more fun since the swap.

And that's really the whole point right there. For 4+3 guys looking for something better to replace the 4+3 on the cheap, a T5 is the way to go.

Well I don't doubt the T5 is a good swap, but I did my own ZF-6 swap, in the winter, on my back and in the garage. Installed Fidanza while I was down there. Never regretted it. Added a Hurst to it and 3.45 D44 rear. Really nice combo. 6th gear gives you thr option of some shorter rear gearing.
Taking out the 4+3, along with adding C5 brakes really changes the 84 especially with Z51 . Overall I'd rather have the ZF because I do think its stronger, and it sorta just 'belongs there'. The swap didn't cost me anywhere near what folks say though. $1500 is a joke, it cost me closer to 2k when I was done. Maybe $1500 for everything used and near non-functioning condition. I had to buy new hydraulics, a hose, new clutch, flywheel, ZR1 pivot for flywheel, then a starter cuz the stupid offset BH. I still think they shift kinda goofy though, and it sounds like rocks in a clothes dryer at idle. really bad.. Of course, my 16lbs singlemass flywheel and unsprung clutch disc and the fact that it's a black tag ZF6 don't help. -- Joe |
shifter is done, it looks sweet will try get some pics soon

Can't be any worse than the ZF6 shifter though. The thing shifts from 1st to 2nd like the shifter on a riding mower. -- Joe |
