Zero star review. Took my suv in as it was having difficulty down shifting. Shop diagnosed it not to be transmission-related but cylinder misfires. Accepted their offer to do the non-transmission related repairs (change spark plugs) at a cost of $700. Problem was not solved and engine continued to misfire. I brought it back in to give them a chance to "make it right". They did not apparently QC the original work, did other work, and that cost me another $800 that was only peripherally related to the original diagnosis. I am now out $1500 and the engine continued to misfire, after which I brought it into my regular mechanic. They qc'ed the original work and found two broken and two loose spark plugs, confirming that the original work was defective in terms of parts and installation. I provided an opportunity for the owner at Mister Transmission Kris Carlson on many occasions to make it right - that is my biggest issue in that he accepted zero responsibility or accountability for any of the faulty work done in his shop. He did not respond to my BBB complaint, would not respond to my several phone calls or subsequent emails. Complete lack of business integrity. AMVIC process appears equally ineffective. Every shop tech or mechanic can have a bad day. The zerostar review is based solely on the subsequent avoidance of the owner to take accountability for defective parts and service, AND the subsequent additional service and parts that did nothing to fix the original problem and was not needed. Please be wary of this business if dealing with them. read more
