This is a warning to everyone not to use AAMCO transmission. I paid $1600 to have my tranny rebuilt , but it still shifts like a dump truck (oh, and it's not a dump truck tranny). I brought it back and complained and the "mechanic" told me he didn't notice a thing. Didn't notice the grinding going into second gear? Cripes.
DO NOT USE AAMCO, they rip you off!
