The Transmission Page

 

 

The 1964 Chevy C60 dump truck that I am restoring has a New Process 540C 5-speed manual transmission. This 5-speed transmission is a selective synchromesh type with five (5) speeds forward and one (1) housed in a cast iron case. A 9½" x 2½" band type parking brake is mounted on the rear of the transmission and standard S.A.E. six bolt power take-off openings are provided on both sides of the belly of the case.
