Transmission info
« on: October 20, 2014, 10:40:03 PM »
Hello all. I recently bought a 1980 c-10 and have a few questions as it is my first rebuild project. The vin has it as having the inline 6 engine, but getting the serial number off of it and calling gm and doing further research, it's a 305 from a 78-79 camaro. Currently the transmission slips out of gear and goes into neutral. So I know that I need to get a new transmission, and do not want to necessarily want to rebuild it because I'm not sure how old this transmission is, and have never done a rebuild on one before. Since this is not the original engine, does the TH350 tranny that's in it come stock for the engine, or the truck? Also, do the transmission mounts go to a certain engine to a certain tranny or is it generally a one size fits all deal? I am currently in okinawa japan and will be back stateside in march/April and am planning on doing a cross country trip, roadkill style. Any info would be greatly appreciated.

Might be a simple fix..... step one is to disconnect the linkage at the transmission then go underneath and rotate trans into drive by hand (feel the detents) and drive it and see what happens. The linkage just might be out of adjustment. Ill let you figure out how to get in gear without getting run over :))
