Who Made the 3 spd and 4 spd Transmissions?
The Greg dropping by here from the 3rd Gen section. Guys can you learn me something, I am trying to figure out who made the manual transmissions in the 1st Gen trucks, the wiki just says:
3-speed synchromesh manual 4-speed synchromesh manual and gives no linky link to click on unlike for the 2-speed Powerglide automatic can you teach me something please Last edited by Gregski; 10-18-2015 at 01:27 PM. |

Re: Who Made the 3 spd and 4 spd Transmissions?
There were 2 3 speeds, once Muncie and one I think Saginaw. One has a longer tail shaft than the other and I believe one has a syncro'd first and the other doesn't but off the top of my head I can't tell you which is which and I have at least one of each. The 4 speed was a Muncie SM 420. Hopefully someone smarter than me will jump in here shortly.

Re: Who Made the 3 spd and 4 spd Transmissions?
In addition to the 3 speeds from Muncie and Saginaw, Borg-Warner also produced a manual 3-speed used in the trucks. I believe the warner was the shorter. Only difference I remember between the muncie and saginaw is the mounting holes on the extension covers
Most of the 4 speeds were muncie or Saginaw. I cannot remember if a 4 speed was made by warner or not.

"The SM420 is an impressive, heavy-duty truck transmission designed for and used in ½, 3/4, 1 and 2 ton trucks. The SM420 was made by General Motors from 1947 to 1967. Military specification versions were made through the early 1980s. The SM420 is found in GM trucks, busses, heavy equipment and various military applications. The "SM" in the transmission's designation stands for Synchro-Mesh, in the tradition of other GM gearboxes, though we have heard that it may refer to Stewart - Muncie, a merged transmission division of GM."

Re: Who Made the 3 spd and 4 spd Transmissions?
The stock Muncie 3 speed was the MC318 and it was not synchronized in 1-2 gear.
They did use several Borg Warner 3 speeds...... T-16 HD but that was in 1968 in GMC. Borg Warner T-89 HD synchronized 3 speed was correct for 60-66. Saginaw wasn't used in the 1st gens from the factory that I'm aware of. Powerglide was the auto trans until the TH400 was optioned in late 65 or 66...... And the 4 Speed was the Muncie SM420 as listed above. The SM465 came into play in 68.

Our first new truck was a '69 GMC (straight six) with a column shifted Saginaw. We removed the 3 speed and replaced it with a floor shifted Saginaw four speed. They are the same external case and dimensions. K

Re: Who Made the 3 spd and 4 spd Transmissions?
I can tell you that my 1965 C10 had a 3OTT and first was NOT synchronized. What a pain that was the first time I drove it. I decided right then and there that it was gonna Go - Go - Go!
