Clark 401V
401V is a 5-speed manual transmission created by Clark and used in Chevrolet and GMC cars.
Synchromesh engagement of second, third, fourth and fifth speeds results in quick, clashless gearshifting. Mainshaft, countershaft, reverse idler shaft and all gears are machined from alloy steel, carburized and hardened for durability. Shafts and gears revolve on roller or ball bearings or fluted bushings for high efficiency and long service life. Power take-off openings are provided on both the right and left sides of the transmission case. Drum and band type parking brake is mounted at the rear of the transmission case.
Drive gear on the left side provides 381 RPM at 1000 engine RPM. Drive gear on the right side provides the same 698 RPM at 1000 engine RPM.
This transmission usually requires 14 pints of lubricant.
