A new final drive to transmission gasket (Part No. 1627494) currently available through WDDGM has been released. When installing these gaskets, the listed service procedure must be used.

2. Clean both gasket mating surfaces on the transmission and final drive and inspect these surfaces for nicks, machining lines or warpage. Also ensure that the bottom edge of the final drive housing does not interfere with the transmission pan.
3. Position the gasket onto the final drive unit, and install the final drive as outlined in the appropriate Buick Chassis Service Manual.
