Unable to give even an estimate over the phone. Once you take your car to them, it's either pay for the tow service (if required) without having them even open the hood or they completely tear-down the transmission and rebuild it. When I asked what needed to be done I was told they would only do the necessary work in order to keep costs to a mimimum for me. When I picked up the truck ('97 Jimmy 4x4) it was over $2K and the repairs were limited only to a complete teardown and rebuild.
Pros: Quality work, on time
Cons: Overly priced, shady get-you-in-the-door techniques
