Did the "T" bar mod today. Went 5 and a half turns, till I felt some resistance. Very unexpected results. Part throttle shifts are now right on time, and nice and crisp. It now tries to go into 4th, but can't, it just free revs instead. After a couple of miles with the trans now properly warmed up, it goes back to it's old behavior, which was and is just staying in 3rd, making no attempt to go into 4th. So now I'm thinking that it's a K-2 piston issue, but reverse is also dependent on K-2 and reverse seems fine. So still no 4th but I'm still glad I did the T bar mod anyways because the first three gears are working splendidly now.

So what is the final verdict here? Tjts1 isn't sure if he wants to sell his trans. I can get a gasser trans for next to nothing anyways, and now get the benefit of a lower first gear ratio to boot. Can I use a gasser 722.3 trans?
