The first experience with AAMCO was in Memphis, TN. They rebuilt my 2008 Ford Fusion transmission and gave us a 12,000 mile / 1 year warranty for the bargain price of $3200.
After 18 months the transmissioned failed again and the AAMCO in Keller, TX, said the case was bad and should have been replaced in the first place causing the 2nd failure.
We thought AAMCO might work with us but since they are all independently owned and operated and one of the requirements for ownership is that you do not have a conscious and can sleep at night after marking up parts 300% and charging over $100 an hour labor for work that is slipshod at best, no deal. In fact they charged $4000 but graciously offered a $465 discount.
For $6500 you can get the lifetime warranty!
Poor customer service; don't care attitude; unbelievably bad group to deal with. Stay away!
There are good people and good certified garages but AAMCO is not one of them.
