T case leaking problem

[Teddy]

I managed to create a little problem for myself. When ever I changed out my speedo gear I pinched the o-ring and now it leaks. I thought I'd be smart and just silicone around it, but it doesn't work for long. I need to get another o-ring, but I'm not sure what the part is called the o-ring goes on. Anybody know?? I would imagine ... speed o meter is in there somewhere?

If you notice that your speedo assembly is leaking ATF (after a day or two), you probably tore the o-ring on the speedometer adapter. This is a very common occurrence. Be sure to generously lube the o-ring area with ATF when you are inserting it into the t-case to help ensure it does not tear again. You can obtain a new one from the dealership or from such places as ACE Hardware, an auto parts store, etc. Just find a place that has an o-ring selection. Here are the specs for it:

Outside Diameter = 1 7/8-inch or 44mm
Inside Diameter = 1-9/16-inch or 40mm
Wall Thickness = 3/32-inch or 2mm

Thanks Paul, you were all over that one. I'll see if Advance Auto Parts can't help me out.

no prob. You could probably find it at a dealer, but the auto shop would probably have it cheaper. With those dimensions, you should be all set. I'll see if I can find a PN for ya just in case.
