hi y'all,
working on little things now. on the speedo cable driven gear. i have removed it from transmission. it is a 12T. is this a press fit into this housing which threads into the transmission?? problem is speedo not working. i have run cable with drill motor and both odo and needle move. if i connect cable and driven gear to tranny-remove cable at speedo--observe cable not turning when driving down road. right now i think either the teeth on driven gear are wore down or gear on trans shaft are wore.
not sure i want to crawl under truck and observe with rear wheels turning,truck in gear and engine running to see if exterior end where cable goes is rotating. any suggestions where to get driven gears??
also i have been trying to ID transmission. I have 51GMC 1/2t LB with 228/6cyl and 3 speed on column. i cannot match the casting numbers with other websites to ID. casting number on linkage side is 3686832 GM 23, casting number on passenger side is E31 GM 591616. Stamped number on rear driver side is J0I4450. ANyone know what kind of tranny this is?? Think is Saginaw 3 speed but not sure.
