I'll tell u......i'v never built a tranny before until i got screwed on a deal by a local so i started doing my own with the help of Rick at A&A and he gave suggestion on my first basic build and from then on all my tranny parts were from A&A(drums,sprag,etc.)That last tranny has been in the car since 06 and has been 1.28's@3350 lbs so i'm very happy with the sells/service
