Transmission, Automatic
Clunks when Shifting from Park to Drive
The 86 model and some 87 automatics used rivets to secure the torque converter drive plate to the hub/input shaft inside the front of the transmission it is a triangular flat -- these rivets can become worn and allow some movement -The Porsche approved fix is to replace the rivets with bolts which is how all the other transmissions are made .
