Its never slipped. Every blue moon it elongates 1-2 but that's about all it does... ONE time it banged into 2nd. Also, when I slow to take corners, and accelerate it doesn't move quick, kind of like it didn't downshift. But this all happens far and few.
136k. I just changed filter and7 qts. The fluid was dark and magnet was nothing different from any other broken in trans. No shavings, just a metallic sludge.
might as well change the shift solenoids too while youre there.
Id do that and put a transgo shift kit and call it a day....if you're doing it yourself. however if you are paying shop time, it would probably be more cost effective to swap the whole unit out
it comes with different shims and springs you can make it shift hard or just a little over stock, honestly i throw as many shims as i can fit in there and it never shifts too hard for me
