I have a 58 f100 with a 292 in it that I want to put a OD behind.  I love the three on the tree and want to keep it, so I have located three potential OD that might work.  They are a unit out of a 55 f100, one out of a 63 f100, and a t86e-1.  I dont know if any of you have any experience with this but was hoping somebody can point me in the right direction.  I know that the trucks had a larger input shaft then the cars but seeing that these are out of trucks I think I am in the clear on that.  If you need any other info let me know.  Thanks in advance.

The 1955 and 63 units should be similar or the same. Either should work but the 55 will have 6 volt solenoids while the 63 is 12 volt.

To work in your truck the trans must have the 1-3/8" input spline. The 1" and 1-1/16" car units have shorter input shafts that won't reach the pilot bearing or engage clutch splines correctly.

The transmissions with tin top cover are weak as are the ones with square side cover. The best have a side cover that is curved at the bottom. I have seen one in a truck but most had the square side cover. NO POWER SHIFTS with the square side cover or tin cover  units or you will be looking for another one.

Thanks so much John.  I will try to get the 63 seeing that I have a 12 volt system.

All 3 are probably a version of the T86 and they are tougher than most people think. I bought my first one almost 50 years ago and the earlier ones took a lot of punishment. T89s are stronger, but harder to find. The only difference in a 6 or 12 volt is the solenoid. I have used governors interchangeably. You will also need a relay. They are on eBay all the time but none of them ever go real cheap. I have used a power seat relay from a Chrysler. The relay is actually like two relays. The heavy winding preforms the shift and then a lighter winding holds it in gear. You will also want a kick down shift or possibly a toggle switch to shift from OD to direct for more power.

I expect the two 55's are about the same, probably T-86's. The T-89 is the truck version of a T-85 and like the previous post said, are tough as hell but relatively scarce. If you have a truck the input shaft may work. My T-89, that I'm attempting to put in a '56 Ford car has an input shaft that's 1/2" too long. My choices are to find a car input shaft that's 6" long or get it cut down. Measure the one you've got (if a T-89) and see if it's 6". If it is and you need a 6 1/2" I'll trade with you. Mine is a 10 spline. I've got 2 T-89's that I've made one from.

not to high-jack this but how do you tell the difference? I just bought an OD Y block tranny that has the big truck input shaft on it but that was all the info i could get from the seller..

If you are asking how to determine a T86 or T89, The T86 had a tin cover on top. The T89 has a 9 bolt cover in the side that houses the shift forks.

so the T-86 was a toploader and the T-89 was a side loader.. good to hear cause the one i grabbed was a side loader..

I wonder if the "inferior-to-BW/T85", Ford "paper" transmissions fail under power shift due to an excessive drive train power application, or due to the type of gear over-sliding impact/damage that the Hurst "Syncro-Lock" shifter was designed to prevent?

Missed out on the 63 and not sure about the 55, still working on it.  The t86E looks like it might have been out of a studebaker and I dont even know where to begin figuring out how to make that work.  Will keep you all posted.
