I took my truck to AAMCO in Bear DE for a diagnostic check of my transmission for $105. The next day I get a call from Dennis telling me that the test was inconclussive and needed to do a more extensive test to determine EXACTLY what’s wrong with my computer. That test was $189.00. He seemed honest, so I agreed to the test. The next day, he told me that I needed to rebuild my transmission for $3900 (assuming nothing else was wrong inside once they opened it). I took my truck to DELTRANS on Old Baltimore Pike (about 4 miles away) and they told me that my transmission was fine and the problem with my truck had nothing to do with the transmission; it was a knock sensor in the engine. They only charged me $89 for a complete diagnostic. I still wasn’t sure, so I paid another $95 to the dealership for a diagnostic of my transmission. They also told me that my transmission was in PERFECT condition and told me that the problem was related to the knock senson. When I confronted AAMCO, the manager, he told me that he was not going to re-imburse me because when a person gets fired at the end of the week for doing a BAD job, they still get paid. He also said that because I gave a bad review on AAMCO.com, he was not willing to work this problem out. Basically, if you have AAMCO rebuild your transmission, you have to worry if they actually rebuild your transmission or if they do, did you actually needed it done.
