Transmission, Shift Arms and Trunnions

The 3-speed manual transmission was rebuilt using new bearings, seals and gaskets. The blocking rings and synchronizers were in good shape so they did not need to be replaced. Gary N. of Tri-County Motor Parts located in Glens Falls, New York assisted in the rebuild. He has many years of experience working on engines, transmissions and rear axles and currently is building engines for dirt track racing and muscle cars.


The original shift arms and trunnions were very worn and had developed excessive free-play. My favorite machine shop owner/operator, Josh W. of Kingsbury, New York and I came up with a simple solution.


Below are the trunnions before being turned down. Notice the wear.


Rather than fabricating from scratch it was determined that the trunnions could be turned down a minimal amount to make them true. Bronze bushings were pressed into the shift arms completing the upgrade.


All of the components were sandblasted and finished with Dupli-Color Engine Enamel.
