Our rubber support mount for the front transmission
case is used on the following vehicles:
Porsche 356 Pre-A (1950-1955)
Porsche 356 A (1956-1959)
Porsche
356 B (1959-1963)
Porsche 356 C / SC (1964-1965)
This rubber mount for the transmission front end is
used on all 356’s from 1950 to 1965 whose transmission is equipped with dual
front support mounts. This concers the vast majority of 356 produced except for
a few 356 B Coupé and 356 B Cabriolet Hard-Top models from 1960 that are
equipped with a single front transmission support mount. Only a few Type 741
4-speed transmissions are affected by this (early 741 transmissions with Serial
Numbers N° 32001 >> 34999). Porsche soon came back to a dual front mount
system which is better able to withstand transmission case torque.
It is necessary to replace transmission mounts on all
356’s. These rubber mounts dry out and flatten with age and deteriorate with
tar and oil projections. This caused the front end of the transmission to droop
or sag which in turn renders clutch action more difficult and shifting of gears
less precise.
