My 1971 Corvette 350/270 H.P automatic transmission lunges when put into gear.
My corvette lunges forward or backward right when it is put into forward or reverse gear. If I didn't have descent brakes the car would go right through the garage. Otherwise the car rides smoothly while driving (stopping and starting while in gear). It's just when I put the transmission into gear. I wasn't sure if the tranny needs a complete overhaul, or just a torch converter issue. I wanted to get some advice from someone who possible has had some experience with this before I go to a mechanic. I'm completely in the dark when it comes to transmission, and would greatly appreciate any information before seeking professional help. Thank you!
