Gentlemen,

I have a 3 on the tree 1984 C10 with the original 250 inline 6. I bought it used in 1985. This truck is as basic as it gets. The only option installed was a step bumper.
The original 3 speed was replaced with what I think is an earlier model 3 speed (long story).
The current 3 speed is in need of a rebuild, but I'd rather rebuild and install the original transmission model. I am having difficulty determining the model 3 speed that would have been installed at the factory. I can't start looking for one until I know exactly what I'm looking for.
Any help will be appreciated.

Should be a sticker on the glove box door that gives the RPO code for the transmission the truck was built with. Post it someone will tell you what transmission you need.
