I have been having issues with my transmission going into reverse and I just called a tranmission shop that ios charging me $1200 to rebuild.

I told him my problem and he said something that an a cap is the problem...... ok my question is what part is this? acap, a cap? I talked to him over the phone but I dont know what part this is or how its called correctly as I cant find it anywhere

Any help?

 

If you want a good answer, go talk to the shop manager in person.....face to face !
Talking about issues over the phone is not going to resolve your reservations at this point.
So, I'd advise ya to get it straight from the horse's mouth......!
