I'm not happy with my 1-2 shift. It's notchy as hell and killing my 0-60. Has anyone had there tko modified by Liberty gear or similar and been happy with the results? How about a different shifter? I'm sure the trans is set up correct.

A shifter helps a bit, you get ride of the plastic bushings in the original shift and get steel ones snugs it up a bit.

Todd.....

I have heard - (have no personal experience with this) - that shift quality will be really degraded if your tranny fluid is TOO SLIPPERY.... sounds crazy -- but some of these trannys have a syncro issue that causes shifting problems if you're using synthetics or the wrong fluid type etc.

I had quite the long talk with the Detroit locker people at a show they had a booth in -- about using synthetics with posi units... and they're saying DO NOT USE THEM IN THEIR REARENDS... just use 90wt.

So just thinking the old "keep it simple" when looking for an issue and start out with the little things first.

I'm running synchromesh as designed. I haven't heard many complaining about the 1-2 shift. The new engine redlines at 6800 and I found 2-3 shift to grind a few times at El Toro as well in the 0-100-0 They are known for high rpm shifting problems as well. Maybe I can just get the new guts and swap them out. A t56 magnum would be optimal but I'd have to slice up the tunnel and it just wouldn't be economical.

Seems you're suffering from "mid plate" tolerance issues....

Todd, you might be a good candidate for that new RS600 trans coming out this fall... assuming the 1-2 shift isn't still an issue. They say similarities to the TKO but zero cutting required for install. I think you saw that thread on team camaro.

ive had this issue in a fwd car with big power.. and it was solved by running AFT fluid in the manual tranny .. quick, crisp shifts.... and if a t5 can run on ATF then so can your tko
