Stutz will not bolt to your flywheel housing. I'm sure the tail shaft is a different spline. The T86 is pretty tough. I always had Hurst Mystery shifters and I came home with no low or reverse ever so often. Once I got married, the transmissions must have gotten better, because I don't think I lost a cluster gear after that. With normal driving, a T86 will last a long time. A T89 is better. They ever put them behind the 390.

Is it possible to get a car OD and use my existing trans to make it work?  Either disconnect the OD portion and connect it to my current tranny or use the input shaft from the truck to make it work?

I have a car overdrive transmission in my truck. I took the tranny apart and put the truck input shaft in it. I have the overdrive solenoid wired to a toggle switch. I turn it on and off as I need it. It's a heavy enough transmission for me, I race with it, but I've only got a hopped up 239.

Dennis, How hard was it to do that work?  Could you guide me through it?

It's not that hard. If I remember, take the side cover off and pull the gears out. I think the input shaft pulled out into the transmission, that's why I removed enough gears for clearance. Put the truck input shaft in , put the gears back in, you're ready to go. I have a 3.92 rear, and in overdrive it gives me the effect of having a 2.43 rear. At 65 mph it's great.

Not to confuse the issue, but, I have always thought the tin top cover overdirve was a T-86. Then I got a T-85 in a trade with a few spare parts. There was a spare side cover for a T-85 that clearly was marked T-86. Now I'm confused.

Before trying to swap input shafts count the teeth on the gear. I'm not sure they're all the same.

The T85 has quite a few similarities to the T89. It is also is a stronger transmission. The T85 and T89 both use a 9 bolt side cover. The T86 was the one with the tin cover, The T86 was limited to about 300 cu in engines. The T85 was used in the police interceptor and the T89 was used in the 60's on 390s. Before you try swapping parts, you need to get a Ford parts book. They made a dozen input shaft/cluster gear tooth count combinations. The weak part of the T86 was the cluster gear, but the good part was it only got low and reverse. I just had to remember to park where I could go forward until I built another transmission.

Does anybody know/recall if  the T89 has a synconized 1st gear?? I know the T85 sure don't!!!

Only second and third got the brass synchros. You had to double clutch a T89 to get it into first when you were rolling.

Dennis or anybody else,

if I get a car OD and do the input shaft swap do I have to do anything to the other end, output shaft, to get it to work with my driveshaft?  I know I will have to shorten my drive shaft but anything else?
