I went to a Cottman Transmission in Sacramento 10 yrs ago to check a 727 tranny that a Cottman in Atlanta had rebuilt just before I moved, because it still showed "morning sickness" (drain back from torque converter overnight). I thought I was getting a warranty look, but they gave me their standard "free inspection" scam. After the guy pulled the pan, he called me over and showed me "your clutches are failing", about all he could say in English. He had thrown a piece of cork gasket in the pan. I told them "put it back together". They did, re-using the same gasket and oil they had drained. I had to pull the pan later to install a new gasket to stop the leaks. I suspect that transmissions shops ruin more than they fix, like all the A-604's they put Dexron in, giving Chrysler minivans a bad name. That Cottman had cars stacked outside to the yahoo, always sitting there whenever I drove down Arden Way. I suspect they were being held hostage until the owners paid for new clutch plates. I reported them to the CA inspectors.
