Reliable SM420 Transmission for Sale

The SM420 is a heavy-duty manual transmission, introduced into the competition by General Motors in 1947 which lasted for two decades before the production stopped in 1967. This SM420 Transmission for sale at our store was a favorite among off-road enthusiasts and truck owners. The SM420 was also used in the military as well.

Features of SM420 Transmission

  • Durability and Strength: That makes the SM420 suitable to off-road and other heavy usages because the transmission is practically immune to wear and tear. It is assumed to bear more torque loads and other severe operational conditions as compared to the other components of the car.
  • Manual Control: Similar to most of the manual transmission types, SM420 has the features of direct selection and shifting of the gears. Manual changing is done using a shift stick that is provided on the interior of an automatic car.
  • Non-Synchronized Gears: It comes with a 5-speed non-synchronized manual transmission- the SM420 and has no synchronization for the first gear and the third gear. This means that in gear changes, due to the frequently high Engine Revolutions Per Minute, the driver has to double clutch to synchronize the revolutions of the engine to that of the gears.
  • Simplicity: The appearance of the SM420 is very simple and does not have any of the flash in modern automobiles but it provides a mechanical feel between the engine and the gearbox which people prefer.
  • Off-Road Capability: With time it may be modified for off-road use as it is well built to handle the amount of torque that comes with off-road exercises.
