Get Saturn parts shows it. http://www.trademotion.com/splash/in...?siteid=214643 Look it up by part number.

Automatic transmission overhaul kits may have it as it is probably available as an aftermarket make fit part.

From a Saturn Parts Supplier (local Chevy Dealer) I bought the 1/2 syncro and also bought a 2nd Gear. I bought the 2nd Gear because the parts diagram indicated it included the needle bearing (Showing it was part of a "kit")

Nope. There was only a 2nd Gear in the box.

The needle bearing might be standard??
I haven't measured anything yet...

The OP is inside of an automatic and will have to find one of the trans rebuild parts places that will talk with him.

Anyone Know who Built the TAAT Transmission for Saturn/GM

[OldNuc]

Not a clue as to the OEM supplier. It is the same bearing 91-02 so maybe the easy fix is to go buy a core at the pick and pull that still has fluid in it.

These guys seem to be part of Trademotion, but they show availability ($27.83) . . .

I think that is the same dealer I posted above. They have several names and use the trademotion catalog system.

A while back I ordered a CKP through Trademotion, but the order was filled by MileOne. Is the Trademotion catalog tied into ALL the warehouses?

[OldNuc]

Yes, they all use it. You can find some will show availability where none exists. I check availability by checking here, http://www.gmpartsdirect.com/ If GMPartsDirect shows no availability then you are usually out of luck. There are none on dealer shelves either. http://www.partsvoice.com/

For the cost of the bearing finding a core trans at a pick and pull is probably cheaper and once it is apart it is no longer mixed metal at the scrap yard. Might end up with a bearing and $$ left over.

For reference purposes, the old part number was 21001512

I'm fairly certain they built the transmissions themselves.

TAAT stands for:

"TransAxle Automatic Transmission"

I'm also guessing that if one were to measure the diameter of the shaft that goes into this part and the diameter of the bore that is goes into, and measure the height of the 21003631 bearing, you might be able to find a double needle bearing that would work by cross referencing it with specs from other bearing manufacturers as I can't imagine that they designed a custom bearing set all on their own (possible but unlikely). I'm going to try to do this and see if I get lucky.

In the mean time, I found one on eBay and bought it. Currently waiting patiently for it to arrive.
