I used the manual pedal setup from a C3 and the hydraulic clutch master from an LT1 camaro. Just made a bracket to correct the angle of the firewall.

It's easier to swap the T56 into an auto C3, the standard trans C3s have a welded in x-member which makes install impossible without cutting the x-member or pulling the engine.

Default auxiliry shifter

Has anyone used an auxiliary shifter in their car. I am using the LT1 that came with the camaro and am considering moving the engine further back (about 3in) in the car to get the more of weight over the rear. this will make using a plate to move the shifter pretty hard. I have heard of a few guys using them in fox bodies but never in a vette. any ideas? excuse my terrible drawings

Torq.... breaks my heart , exactly what I'm doin!


Curtis.... I 've seen something where the shifter has been moved to the center shift cover but haven't seen it in person or drawn.


Torq.... any details on the mounting plate for the correct angle on the clutch cylinder?

Thanks

Yes... I used a stock Clutch and Brake Pedal I got from Keisler. I used the Camaro Clutch M/C and fabricated my own firewall mounting bracket and with reinforcement plate on the inside. The rod pinned right to the Clutch Pedal with no modifications.

One person has used a clutch cylinder from a 85 1-ton truck on a T56 and he says it works OK. The truck cylinder doesn't require an adapter to correct the angle like the late model F-body ones do. I have a McLeod clutch cylinder that came with my T56 but I'll probably try out a truck cylinder first. You can get them at Autozone for $50-something.

The easiest swap I believe was using 98-02 transmission from camaro or firebird. This has a longer input shaft, almost the same length as the original 4 speed that was in my 74. Then I bolted an adapter plate to my original stock bellhousing along with a new extended pilot bushing and bolt the t56 to the adapter plate. There is no change to the original stock mechanical linkage clutch. I did add a new clutchplate & throwout bearingwhile it was all apart. The shifter is back a bit further but I made an adapter to move it forward to the stock location. Or you can buy a custom offset shifter as others have done. For the speedo you need to use a conversion from the electric output back to your mechanical or switch to a electric 5" speedo. I havent done anything yet with my speedo. I had the driveshaft shortened and used a turbo 350 yoke. I found it to be a fairly easy swap and spent around 1200 for everything but I know prices have gone up on everything in the last 2-3 years since I made this change. I made my own rear mount out of scrap I had laying around but Ive read that the bolt in type used for automatic cars can be made to work if its relocated.

Actually you can use a T56 out of a 1990 something Camaro. We have an adapter plate that mounts the front of it and allow you to run a standard GM bell housing and mechanical linkage.

Who makes the offset shifter? From what I understand McLeod stopped making them. I am thinking of doing a T56 Swap in my 1980 auto. I plan on using the Wier adaptor but was just wondering what everyone was using to put the shifter back in the stock hole.

McLoad offset shifter works perfect, its just a bolt on, they offset it to the left 3/4" and towards the rear 1" i believe
Do you have a part number on that shifter??

Hi

Same here, GM Viper T56 with mechanical speedo connection from D&D.
And I also had to install the shifter the way you did, a bit further to the pax side again to make it centered into the original position.

The offset shifter is a bit too far fwd and to the left.

I went with the D&D GM viper unit too. What crossmember is that? Is it a bolt in? Do I need to cut my stock crossmember out? Still trying to figure out the best way to mount it. Where is the mount located as compared to the stock mount. I know it is farther back. How far. Is it also lower? If so how much?

Did the bowtie crossmember need to modified?

Okay, can anyone tell me if the trans tunnel is the same for C2's and C3's? I've heard the T-56 is too big to fit in a C2 without butchery of the tunnel, something I am not willing to do. You C3 guys seem to get a T-56 to fit right in. I am about ready for a new trans but I am not convinced of the TKO conversion (seems to me to be only about a 50/50 success rate and it's expensive), the mythical 5-speed Muncie is still nowhere to be seen, and I don't think a T-5 will live very long behind a stout 383 or 427 smallblock.

Honestly, I'd try a richmond 5 or 6 speed with the overdrive. It should be a direct bolt it, but do your research. I have a T56 for right now (not in the car yet) because I got such a good deal on it, but the richmond tranny would have been my first preference. A new one will cost you in the neighborhood of $3200 - $3300 and is supposedly the same design tranny that they use in nascar. Not to mention, it is built in the good ol' US of A!

I did a TKO-600 on my own (no kit). It was very straight forward. Standard flywheel/bellhousing/etc. Did need a different spline on the clutch but that is off the shelf. Bought the trans from standard transmissions in Fort Worth. They put in their own offset shifter for me (cheaper than the McLeod style) and I bought the correct ($200+) yoke from them.

Made my own bracket (rather than butchering the crossmember). You can buy a similar bracket from the conversion folks if you don't want to weld up your own.

While not cheap, I expect it's less than a T56 with new components. Of course if you get a T56 used for cheap, then it's no comparison. But then when that used/abused trans built for 300hp frags behind your 500hp motor....

I am more than happy with the TKO and would do it again.
