A Question About Keisler TKO Vs Rs Tranny
Not a thread about Keisler in general but simply about the differences between their RS series and the TKO transmissions. Disregarding the differences in the gearing I guess I don't understand why they had two different transmissions that seem to be very similar. Both had similar torque capacity, both were 5 speeds and both were direct replacement for the Muncie. I think they were both available in close and wide ratio too.
The one difference that is noted is the improved shift from 2 to 3 with the RS. Oh, it was a couple hundred cheaper too. So is that it?
I'm waiting for the TKO 600 to arrive off the boat to put in my '64 and I was just wondering. (I should have known this already!)
Can anyone shed some light on this for me? I can't really ask Keisler now can I?

RS/SS are completely different transmissions from the TKO, and it is not truly a "direct replacement" as both are longer than a Muncie; therefore making installation a bit more challenging......

Ah yes, the different case for the RS/SS. Was the RS/SS made 'in house' and could be correctly called Keisler transmission while the TKO only re-engineered by Keisler? Is the RS 2nd to 3rd shift truly better?
Thanks.
Bud.
Thanks.

The RS is a ford mustang T5 I believe. keisler added Carbon fiber clutches so the 2-3 shift is smooth supposedly at 7000+ shifts. I havent tried to prove that yet....

I can't speak of the RS/SS but i just installed a tko 600 in my 66 327/350 coupe. I don't have any problem with the 2-3 shift. From what I understand the problem manifests itself during high rpm shifts.

Would there be any links or pictures of installing the 6 speed Hurst. I was told the 6 speed would not fit the 64. I assume this was the wrong info given to me. Thanks

RS and SS differences
The Keisler RS series was a modified Borg Warner ( now Tremec) T45 Transmission. Not a T5. The SS700 was a Modified Legend LGT700.
Keilser never made his own transmission.
The TKO was obviously made by Tremec and is still available. Keisler never did anything to the blocking rings and all T45 units came with carbon fiber rings. The T45 was a short lived production 5 speed in the Mustang, thus ALL Keisler RS units based on the T45, were made from primarily core units. Remember Keisler was no longer a Tremec dealer and Tremec never offered much in the way of aftermarket parts or complete NEW units for the T45.
The T45 and LGT700 use a single rail shift system
The TKO uses a 3 rail system ( thus the bulky top covers.)
The LGT700 that was modified by Keisler is still made by Legend Gear and Transmission. It is still available today and Legend is coming out with better shifter positions and offsets than with Keisler had.

The TKO's from Tremec were the first available solution to the 5 spd overdrive need for muscle cars. Then came the RS and then the SS.
From what I have found out, the early TKO's had different endplay specs on the main and countershafts. This was one thing that helped lead to the high rpm shift problem reputation. It used to be something like .015, and they found that tightening them up helped the shifting. I think the new spec on all the tremecs since ?? is .000 to .004. This was not the only problem, but was something that made a difference. When I changed the 5th gear ratios in mine, I put the main shaft at .000 and the countershaft at a -.002 per Tony Sarvis at AstroPerformance.com. He knows these transmissions like no other - he is also the place to go to for parts or problems with the Tremec's. Bought everything i needed from him, at a really good price, and he had great advice on what I should do while i was in there. He also has a few solutions to help the shifting, and knows which tricks really work, and which don't.
Just figured I pass his info along since I had trouble finding where to go for parts for them, and couldnt be happier since finding him.

the SS was (and still is) made by Legend Gear. Keisler supposedly 'customized' it for direct fit applications. the case doesn't seem to be modified using adapter plates/etc, so i don't know which came first, a transmission by Legend Gear or a design by Keisler and just gears fabricated by LGT...
haven't installed mine yet, but i'm getting itchy palms to get it done....

The LGT700 that was modified by Keisler is still made by Legend Gear and Transmission ( legendGT.com ). It is still available today and Legend is coming out with better shifter positions and offsets than with Keisler had. Its currently available from sprakerracing.com bowlertransmissions.com and 5speeds.com
I saw LG&T added Bowler to their distributor list, but I don't even see the LGT-700 mentioned on Bowlers site (or your 5speeds site for that matter Paul). Be nice if the general population could see whats in the works from Legend as far as the shifter mods required to fit the other 99% of the available market ..not just the few race cars Spraker caters to.. and a solid eta for release. Its understood any price quotes would need to come from the distributor or dealer.
**EDIT**
I just hung up the phone with Jack at Legend. He says they currently have and have had, the ability to modify the shifter locations on their LGT-700 over 7 different shifter locations/spacings, including C1/C2/C3 Corvette, early F bodies, A-bodies, Ford, Chrysler, AMC etc ..said he didnt realize there was no press/blogs/threads anywhere advertising this fact and he'll update their website and/or Facebook page with this news pronto. Just some good news for anyone researching their options or on the fence b/n the TKO, T56, LGT. You'd still need to contact one of their Distributors or dealers for pricing, but it looks like somewhere in the mid-$3K ballpark.

Legend Gear and Transmission would like to say thank you to all that have called, emailed, & posted in the last few days. I know there are many concerns about LGT's status and ability to continue producing transmissions and driveline compon...ents after the recent posts of Keisler's decision to file Chapter 7. Let me first say that LGT and sister company Abundant Mfg., Inc are here to support those that have purchased LGT transmissions, Axles, Shifters, or other driveline components. LGT along with Jeff and Sue Spraker of Spraker Racing are working closely together as we create a distribution network such as Spraker Racing that have the same passion, integrity, and values that we feel are representative of Legend Gear and Transmission. LGT will be announcing a 2nd distributor next week as we team up with another qualified transmission company that can offer additional services and products that will enhance the value of our LGT 700 transmission. We have developed a strong and supportive supply chain for our products and we are very appreciative of the efforts by all to get this LGT-700 to market. I look forward to your feedback and pictures of the projects you've allowed us to participate in. It is your feedback that allows us to continually improve and meet the demands and challenges of this ever-changing market we serve. If you find yourself in the Statesville, NC area please stop and visit us. Please visit our website www.LegendGT.com for contact & distributor information. Jack Simms (VP of LegendGT Operations) along with myself are available to answer any questions you might have.
