Another member was critical about sun valley, my experence with them has been very good as far as used parts go. I recomended them to friend in LA
(house here in OR house in LA) who needed a transmission for his 85 190E (I sold him the car)
he went there to get a rebuilt unit and ended up buying a used tranny for 550 they pulled it apart for him and checked it out, put in seals or gaskets? new filter,and reverse pack.It shifts very well........
