Rear Main Oil Seal

if you need another case I have one.

Also, the fluid was right up, and not the colour of transmission fluid.

The NP246 takes AutoTrak II fluid, which is blue (when new...).

Thanks Steve,

That's actually one of the reasons I felt that my transfer case may have been recently rebuilt. The fluid was still nice and blue. Anyway, I've got AutoTrak II ready to go.

I may be stumped by the silliest problem, the transmission filter seal.

I've done filter changes on my 99 Lesabre, and never had a problem getting the seal out. This one, I'm stuck.

Ideas?


EDIT: No sooner do I ask for help, it comes.

Check out this video. At about 3:14 they show a method to remove it.

Thanks Wade,

I saw that and had been trying to use my picks. Surprisingly, the pick left a slight indentation on the aluminum so I held back on that. Later I got a small screwdriver and wedged it in the indentation I had made and tapped towards the center and got it.

I hate those little seals, they’re a PIA to remove.

There is a trick out there that involves a piece of threaded pipe with an elbow. Screw it in, give it a wack, and it's out. I didn't have any piper at home.

If you check the T-Case fluid and you used AutoTrak (blue) and you notice its over-filled and Red like mine was you may have a internal Trans seal failure. Mine was 2 quarts over (1 GAL) and it didn't leak a drop.
