The Stovebolt Site Forums The Shop Area Engine Shop 1960 Synchromesh 5spd? gear 5 = OD?

Hey guys,So I've been reading my factory owners manual for my 1960 C-10 and under tranny options there are 2 5spd OD options. where these an option on the half tons? Or where they just on the bigger trucks? If anyone has any info on these trannys and know what they fit or if they'll fit a half ton with the 235, let me know. I'm still trying to figure out my tranny options. I really really just want to find a tranny I can just bolt up, no mods. ( I currently have the factory 4spd with the short tailhousing.) thanks! -Danny

Danny:

The factory transmission options for the '64-'66 Chevy Series C10, C20 & C30 and K10 & K20 trucks were 3-speed (manual, column shift), 3-speed w/overdrive (manual, column shift), 3-speed wide ratio (manual, column shift), 4-speed (manual, floor shift, SM420/SM465), Powerglide (two speed automatic) and Turbo-Hydramatic (three speed automatic). This information is per the General Motors Silver Book. I don't believe there was a 5-speed w/overdrive tranny option available. I hope this information is helpful.

The only 5 speeds available at that time were in the real big trucks & would be impractical in a pickup. You can put in the 3 speed with o-drive but they are pretty hard to find & create problems with controls & linkage. The best one to use is the S-10 Borg-Warner 5 speed, especially since you have the floor shifter already. It takes some mods. but they are simple & there is much info. on this websight & plenty of guys to help. I,ve done 2 of them & they work great. I,m going to put one in a 49 Ford panel soon behind a flathead V-8.
