This was a bonus lying in back of my burb i just got. Can anyone tell if this is an over drive unit from a 67,68 maybe? I have a 67 swb/cst that HAD o/d, but the trans is mia. Thanks, Eric

can you give me the part number off it?

That is a GM 64-69 Saginaw 3spd overdrive trans.. The overdrive unit is Borg Warner R-10 overdrive assembly....fairly rare to find these days..
Years ago I used to take those apart for the overdrive unit and put them on the Saginaw 4spd's to have a 4spd overdrive

Definitely a 3 speed overdrive but notice the front shift lever--looks like it's from a 350 turbo automatic!!! That doesn't look right to me.

Neither of the shift levers look correct to me. I agree the one looks like a th350 shift arm.
The number on one side is:3858986
on the other side is GM6 3919365
on the tail shaft R10Q-1
W.G. div.
These are the best i can tell. The date code looks like 67. Thanks...
