Shift Kit for a 727

Kinda hard to guess. Does it kickdown into passing gear correctly? If not maybe the throttle pressure (kickdown) linkage needs to be adjusted. That affects shift firmness on Mopars. If that's not the problem maybe they forgot to do some mod on the valve body they were supposed to. Could also have not adjusted the front band correctly. Hate to tell you but I've seen several posts where guys had problems with TCI transmissions. That's why allot of guys say TCI stands for "turns to crap instantly".

But hey at least yours has lasted for a good while. That's a plus. I have read 3 posts in the last 4-6 weeks where guys bought new ones and they either wouldn't go at all or performed very poorly.
