12 speed trans

Recommended Posts

I pulled the top off my trans to finally find out why it would not always shift into high range, Hit and miss all the time. Put all new rails and pistons with o-rings in, no help. I found the housing to be worn where the high-low shift rail goes through. Does anyone have the housing they want to sell? Mack dealer is having a hard time finding one.

Live every day like it's your last, because one of these days, it will be.
