67649I need a truck 676593 speed transmission with attached overdrive. The transmission I need says T 86 E-1A. I think the overdrive will show R10. Does anyone have this to sell to me? Please also read my follow up post on this series of posts, it gives more detail. The overdrive I need comes from a late 40's to mid 50's truck. The pictures show the overdrive I need. Unfortunately, there are quite a few variations of the T 86 E-1A which complicates this.

What is it going in? Do you need a long or a short tailshaft transmission?

I have a very good T86 out of a 64 Daytona which is a long tailshaft transmission, for sale in Andover, MN.

The T86 case was used in a number of different transmissions, so that number doesn't narrow it down enough.

Yes, the T86/R10 was used for almost thirty years in cars and trucks, but there are variations; 6/V8, 6-v/12v, early and late bolt patterns and tailshafts.; tell the experts here exactly what model and year vehicle and what engine you have and they'll tell you what years, makes and models will interchange. Those trannys are thick on the ground, so one will be found for you. I've got a '56 V8 car tranny; worked well when pulled.

I had no idea this could get so complicated but here goes. I mentioned initially that I need a T86E-1A. The vehicle is a 6 volt 1953 2R5 with a 1951 car Champion engine. I say car because the engine's serial number is 758205. Attached to it is a truck bell house of (I'm guessing) late 1940's to mid 1950's vintage I believe I need a short tail overdrive. The transmission I took out of the truck is a T86E1 and is not made for overdrive. That transmission's input shaft has a 5/8 inch diameter tip which is about 1 1/8 inch long. The ten splines are 1 1/2 inches long and the splined shaft is approximately 1.124 inches diameter. The rear part of the input shaft is 1 1/2 inches in diameter. As for the bolt pattern, the horizontal bolt holes are 5 15/16 inches apart on center. The vertical holes are 5 11/16 inches apart on center. That is what I have. Does anyone have an overdrive/transmission that will work in my truck?

Some Trannys with T86E Cases will actually BE T-90 Truck Transmissions with a Lower 1st. and 2nd Gear and SOME will have the Champion small Six Input Shaft that you need.

So counting the Low Gear Teeth may be one of the Few ways to know exactly what you have, after of course weeding out the Long Tail slide-in Driveshaft Yoke Car versions.

If this pickup is going to be a "Cruiser" and not a "Hauler" a Car Trans. should work fine, the only problem there is that small Six Cars got the tiny little T-96 Borg Warner, not very strong and probably won't bolt up to your Truck Clutch Housing.

Yes, until you or someone does a whole lot of Measuring on the Replacement Unit it WILL be confusing, but can be figured out.

If using it as a truck, the wide ratio T90 version is the one to have. If it's a hobby vehicle which will not be loaded as a truck, then the closer ratio car T86 will work just fine.

Does anyone else think a '56 car T86 overdrive will work with his truck bellhousing? It's short tailshaft, fixed yoke and the 12-volt solenoid can be swapped for a 6-volt.

I used a car sourced OD tranny in my (ex) '53 2R5, the only big deal was getting the drive line shortened. With that truck 4:88 rear end the OD was a nice addition! I believe the transmission came from a similar vintage Champion.

Why not just get a car bell housing and the car transmission? Seems like going from a car engine to a truck bell housing and then back to a car transmission is asking for problems.
I have an OD trans and bell housing from a 50 Champion that I would part with.

It takes quite a bit of studying the Two different Models Chassis Parts Catalogs to determine what works and what does not, unless you have quite a lot of "hands on experience" with many years of Studes.

The suggestion in Post #10 would be a good and simple one all except... the Truck Clutch housing is just SO majorly different and so are the Rear Mounts that it makes this "Simple" swap very difficult requiring "Fabrication Skills".

I can remember several R Series Trucks that came into the Dealerships I worked at with V8 Car Engine "Conversions" that were so bad the owner gave up and brought them to the factory trained experts to replace half of the parts with New CORRECT 1955 and on Pickup parts.

I guess it was because AL Gore had not yet invented the Internet, so they had NO help! :D

Can anyone give joe and me guidelines of how the overdrive cases for '40s cars and trucks differ from the later versions? I've got a complete R10 but no idea of the year.

Some of these models of transmissions have a threaded lug on the bottom for the clutch lever support and some are not threaded for different applications. However it would not be too difficult to thread the casting if need be. The electrical components in the OD are interchangeable between 6 and 12 volts, and spedo cable drives can be modified to fit.

I have the transmission you need. How soon do you need it? I usually come to Minnesota for a short time in the summer. I will also be going to South Bend.
you can write me at studepickups at optonline dot net. This is a truck transmission with the shaft that will fit the Champion engine. I am curious about what is wrong with your transmission?

The transmission you describe here is for a Champ Pickup.

I have a three speed od tranny from the pickup that I bought from Joe Hall to use in my CE when I was planning to use the stude v8. I'll sell it for a lot less than I paid him for it.;)

If your truck has a champ motor the V8 has a different input shaft. I rebuild transmission for your application or can sell you an input shaft that I alter to fit the passenger car transmission. Call me at seven one seven-three 0 eight 1800 for more information.
