I brought my 2001 Mazda Miata to them for a loss of power and engine shake on March 15, 2013. Thy had the tech Andy Seevers take a look at it, and came back with the transmission was slipping. The quote was $2,800 for the repair. This seemed high to me, nor did I ever noticed the transmssion slipping, not ever feeling/showing on the RPM gauge. I picked the car up, paid the $65.00 diag fee. I took the car over to Mazda South, and was told by the dealer that the u-joints were gone, and would be $956 to replace the drive shaft. I picked it up there, and took the Miata to AAMCO, who told me the u-koints were gone and would be $950 to replace the driveshaft, with new, replaceable u-joints. AAMCO could find no problem with the transmission. I talked with Jonathon at JC auto, and he could not give me a reason other then the mechanic took it for a test drive, and thought if felt like the transmisson was bad. I was really disappointed in this, I took it to them from S. Austin after reading the great reviews. Use at your own risk, it seems their mechanics are trying for more repairs for higher commision.
