T90B or T85C?

Once again thanks for all the input and advice. This forum is the best troubleshooting guide out there! As a town driver the tranny does well and has plenty of pull but get it on the highway up to 60 mph...I can fully understand the need for overdrive! When I look for an overdrive tranny does it have to be out of a Stude and I assume I should be looking for a T-89? Info from the internet: T-10/85/89 all had the 9 bolt side cover, but the T-89 shift arms were (stagered) not inline like the T-10 & 85. The shift arms on my tranny are slightly offset, the rear is lower.

Not trying to beat a dead horse here but with less than a year owning a Stude I'd rather ask the "dumb" question rather than find out the hard way I was wrong!

Well I have been known to sell a part now and again, trade for something once in awhile and on occasion just give something away. Of course, in the grand tradition of carrying on the business founded in 1939, I do prefer to the former as opposed to the later.

Know anybody that needs one? Feel free to send them my way and know I greatly appreciate your kind tolerance and continued patronage.

Anything can be made to fit anything, but pretty much, yes, it needs to be Stude.

The Studebaker T89s have unique input shaft dimensions. It is also one of the few with a short tailshaft and fixed rear yoke. Most of the BrandX versions used a long tailshaft and a sliding yoke.

Fortunately, the T89 is relatively common. Make sure you get one with a governor and solenoid and ideally, the kickdown switch and relay. They are expensive to buy separately.

To: bomarkham,----Well Thank You. I just may take You up on that offer. And whether You realize it or not You accomplished something that I always new You could.......
You managed to express a thought without directing any sarcasm towards good old SN-60 (I think!) Thanks!

As Jack said you most likely have a T-89 with a T-85 case, which is what they used on most T-89's wih lower ratio gears.

Your original error was looking up the Trans. type as T90 which is for a 6 Cyl., with the V-8 Engine in a Truck, you would have the side cover, H.D. T-89 Trans.

The Rear Seal is different than T-85, or T-89 with Overdrive.

My Champ and every other one I have seen in Australia (rhd) have a T87D. A three speed with the gearstick through the top of the case.

They must have not wanted to use the U.S. type setup because they would have a problem with a column shift on a Right Hand Drive so they took the easy way out, a floorshift for a Dodge or Ford maybe, we never used those here on Studes.

Let me know if you want one. I would be happy to ship it over!

The seal that SI has listed for a 63 Champ (P/N 1541097) is a perfect fit for the T85/89 non-overdrive transmission. It doesn't look anything like the 49 year old seal I pulled out, but it doesn't leak any more!
