1991 cutlas transmission slams hard when slowing to stop at 11 miles mph 3 rd gear only tested it in 1st 2nd
Sounds like it isn't downshifting properly. I would just be guessing at what the issue is, best to have someone qualified to look at your vehicle to see if it is the trans itself, the valve body in the trans, and or the linkage, etc.
I was experiencing the same problem. It is the Torque Converter Solenoid not disengaging the torque converter as it should when you slow or come to a stop. My Ace Mechanic unpluged a small electrictal plug on the front right under the hood going into the transmission disabling the Solenoid and the problem was solved. You will experience reduced fuel economy on the highway (since the torque converter does not lock in for overdrive)... otherwise no more problem. The Torque Converter Solenoid is inside the transmission... inside the valve body... not a simple replacement. Best Regards, Zak4208
