TKO 600 Modifications - Lateral-g Forums

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

Maybe these guys can give you some info , there's a guy by the name of Grey, the company is the Driven Man. Ive talked to him a few times, nice guy. They have an option for the TKO-600 its called the extreme 600. Perhaps they adress some of the issues your having.

I had a conversation with Brad at Liberty gear today. They will tear it apart and do all their magic to it for about $500. It's about half price if I buy the parts and do it myself. Different synchros, forks, polished shafts, etc. The real problem is it's a 6 week wait right now. I want to run at Buttonwillow on September 25th and don't want to be out of commission that long in the fall. More than likely a winter mod unless I decide to tackle the project. That or I'll just have Rodger at Ironworks cut up my baby to fit a 56 magnum.
