I have just bought a new, modified 600 from these folks: WELCOME TO LIBERTYS HIGH PERFORMANCE. The car is in Dennis Olthoff's shop for some major work and will have the new transmission installed when I get it back in about a month. I will post my impressions after I have put a few miles on it. I am guardedly hopeful.

My prediction is that you are going to be very happy with the Liberty version of your TKO 600. If you did the upgrade and removed the old pieces, compared them to the Liberty replacements and how they worked / were timed, you would have no doubt in your mind about where the problem lies.

This is a Tremec issue yet again and right on par with their third gear mainshaft / countershaft misalignment that precipitates the premature third gear failures. Good shifters can mask the 2 - 3 shifting problem somewhat but they can not correct the bad internal design of the shifter rails. Liberty's upgrade does!
