Default Transmission rumbling when accelerating.

1990 740 turbo. Rumbling and vibrating when accelerating. Automatic transmission. Universals are fine. Seems to be the transmission. Oil level was low due leakage at rear seal. I added fluid. No change.

Check the driveshaft center bearing and mounting donut. Also check the transmission mount as well as the motor mounts.
