Would a MT-90/Heavy Shockproof mix cure that? Or aid
Well if the trans isnt shimmed tighter then stock its going to break. Thats basically what "built" transmissions are. There blueprinted stock gear boxes.
Im acually running 1qt 80-140 and 1qt 80-90. It shifts like butter. Im going to flush it out this weekend, and refill it with the same stuff. Theres so much hear say on the internet who knows whats true or not.
Jacks recommends the heavy shock proof/vavoline 80-90. TRE says that the shock proof is a bad idea in the trans. Some people run it, other people say no.
I got 80-140 weight coastal and 80-90 chevron syntech i get from work, and it feels great.
