View Full Version : I need help identifying this transmission

07-19-2017, 02:19 AM
I bought this 4 speed a few years ago and was told it was pulled out of a '63 GT Hawk. I would like to drop it into my Hawk, but heard that it could be a 62 model and finding a bell housing might be an issue.


Thanks in advance

If that center to center measurement across those Lower bolts matches your 3 Speed Clutch Housing, it's the Ford pattern, not the Chev. with the weird '61 Housing needed.

It appears to be the later Ford Case T-10 and will fit, but just measure it.

That input shaft looks awfully long, might it be from an AMC product? Keep on Studebakering

Look at the stamped number on the flat boss it will tell you a lot more.

This is a mid 62 through 64 T-10. It will fit the standard late Studebaker V8 bell housing. Make sure you polish the input before using it. 61 and early 62 transmissions used a GM main case needing a unique GM pattern bell housing. I think all of those transmissions were close ratio. 61 was for sure. When the change to a Ford case happened, a wide ratio was also offered. The close ratio has a 2.20 1st gear and the wide ratio has a 2.52 1st.

Also, by the looks of those shift rods, it appears to have an aftermarket shifter. Hurst, maybe? If so, lucky you.

Interestingly, my 62 Hawk has the Chevy bolt pattern with the wide ratio, identified by a groove cut around the spline. Must be one of a very few!

Is there any way I can tell if this is close or wide ratio?

Also, Im not sure what kind of shifter is on this thing. There are no obvious markings on it. The previous owner said it came out of a corvette.

Thanks again for the information!

It is indeed a T-10 from a 1963 Hawk. It's a wide ratio transmission with a 2.54 first gear. Look at the splines on the input shaft, see the groove (or ring) in the shaft, that single groove tells you it's a 2.54 first gear wide ratio trans.

I don't see the groove in that pic. Mine has the groove cut right thru the splines in about the center, probably about a 16th inch deep.
