Tremec TKO 600 shifting problems

Typically if you have a shorter lever, I find it more difficult to change gears, the longer levers that our Backdraft's have, make for a really nice shift. I belive that there is a kit from some of the suppliers of TKO that have different sychro's. I'm not 100% on that.

First, the feel while shifting slow is entirely different from the feel while shifting fast under acceleration. My transmission felt very good and was easy to shift while granny-shifting.

It could be we are talking about two different cases.

Respectfully, I disagree with the long shifter totally Bill for faster shifting. It argues against what many people say the problem is, the operator guiding the shifter.

A short shifter is much more difficult for the operator to guide, the springs and gates in the transmission have much more control when the shifter is short. As the lever is made longer, any driver push error (to the sides) has a larger and larger effect at the gate.

If I had a shifting system that required the gate to be controlled by internal springs (like the TKO 600), I would use a short lever. This would give the springs in the transmission more control compared to pressure errors made by the operator.

As a matter of fact Liberty's actually told me to never use a long lever on the TKO-600. They said to use the shortest handle possible, and to use a ball. Fortunately that's what I already do. :-)

About 4500 miles on my TKO 600. No shifting issues at all. I have had the standard Cobra shifter and recently switched to the Jordan shifter (shorter throw). Both feel great. A few things I made sure of after reading about the TKO on this forum - the hole I made in the tunnel is centered above the shifter, I always use 3rd when I park and shut down, always shift to second before reverse. The only time I have had any issues was when my clutch slave wasnt adjusted properly. Hopefully this trend continues but maybe by me posting I have jinxed myself.

Tom,

I never mention that the longer lever makes faster shifts. But stated that the longer lever made it a nice shift. Respectively... If you take a longer lever such as Backdraft's lever, all you have to do is push the lever forward and it will go right in 3rd gear. I'm not talking speed shifting. Thanks

Bill,

Mr. Bondurant said the exact same to some of our members whose cars he drove at London this year.

I switched away from Bob Jordan's shifter (which is a piece of sturdy jewelry) and back to the regular Superformance lever because the shorter lever lured me into a quicker pace which I thought was not in sync with the natural rhythm of the TKO. This is just for street driving or an occasional track day. I am the exception in that most everyone loves the Jordan shifter. I had the same result with a Cooper S short shift kit. But there it was the emission controls delaying RPM decay.
