Drivetrain Swapping Input Shafts On T5

I have a T5 out of a 2000 v6 that I am trying to modify for use in a '93. I ordered the '93 input shaft and it came with the bearing on it, but no outer race. When I pulled the longer original 2000 input shaft out, the bearing was much smaller on it, and the retainer and race from the old shaft would not fit over the new bearing. I am wondering what my best course of action is. How different are the bearing retainers from the 86-93 vs. 99-04? Is it just the length or is the area in the retainer deeper to compensate for a longer bearing & race? I can find the part # for the smaller bearing from the 2000 shaft, but I don't know the # or size of the one on the '93 shaft. Do I need to swap out the retainer for the 86-93, and if so what specific bearing do I need to use? Thanks. Left one in the pic is the '93 and the right one is the '00.

My zspec used an A1 bearing....that was the part number. Unfortunately, I can't remember if that was the bearing on the input shaft or inside the input shaft at the end.
I can't remember for sure....go to

Seems you're right about the A1, I looked it up and found the application. I'll order one of those and as well a new retainer. Thanks!

The number of gear teeth on the input shaft may not match the cluster gear you currently have... The gear ratios have to be the same or it won't fit.

T5 identifier information.

On the tail shaft of the transmission, there will be a stamped aluminum tag. The tag will have a number on it that you can cross reference to the chart below. There is no other way to find out what type of T5 it is without disassembling it. All the rest of the numbers on the outside of the T5 case are part numbers which are not unique to any particular T5 model.

Remember that 94 - 97 T5's have a longer input shaft (about 11/16” longer) and can only be used with a 94-95 bell housing unless you modify or replace the input shaft.

T5's used with a 4 cylinder have a 3.93 first gear, reduced torque ratings and an input shaft pilot diameter that is smaller that the T5 used for V6 & V8 engines. The pilot diameter is .59" compared to the .668" used on V6 & V8 T5's. It requires a different pilot bearing to be used with a V6 or V8. The pilot bearing you need is for a Ford Ranger diesel from AutoZone part #14672


I don't know how you feel about the DYI thing when it comes to gears, some people don't like the idea of working on transmissions. If the DYI transmission fix idea isn't something that you would rather leave to someone else, here are some resources:

See to download a FREE service manual for T5 or Tremec 3550/TKO
You will need the Adobe Acrobat viewer which is also a free download –

See or for parts

A T5 rebuild kit with syncros, bearings and other small parts costs about $160. It does not include any gears or shafts. also has a video on how to rebuild your T5 or Tremec. It costs about $20, and is worth every penny of it.

I did a Tremec 3550 rebuild, and it wasn't that difficult. The video was an immense help, and I would recommend viewing it. At $20, it will give you an opportunity to look and decide for yourself if you think that it is something you want to try to do.
