I dropped my car off last Friday at an Imports Only auto shop for an oil change and some minor transmission work. The had detected a small transmission leak and recommended replacement of a transmission plug, and pulling the pan and replacing the pan gasket. After work was completed, it will now not go into gear. They said the replaced the parts, and then topped off the tran fluid. They saw no shavings or anything in the bottom of the pan. Anybody have any ideas? Please help!
