Join the "I've been ripped off by AAMCO club. They rebuilt the transmission in my Isuzu Trooper and it sounded terrible from the minute we drove it off the AAMCO property. They kept assuring us that nothing was wrong. Finally out of frustration, we took it to a dealer for a diagnostic and they told us the transmission was full of metal. At that point AAMCO, in Fredericksburg, VA, did the work again. Once again the transmission sounded broke from the second we drove off the lot. We kept taking it back to AAMCO, and they would drive it around and say, "We don't hear anything, but don't worry, if something does happen we'll take care of you." After months of this routine, we went back to the dealer and once again, they said the transmission needed rebuilding. However, at this point the original AAMCO repair is out of warranty and the AAMCO dealership told us to pound sand. Furthermore, the individual who told us the transmission was fine and that he would "take care of us" if it wasn't, has retired to New Mexico and the current management refuses to contact him or give us his phone number.
I guess there is a reason AAMCO only wanted to charge 1/2 of what the dealership wanted for the original repair.
