There's some seepage at the shifter rod....where it goes into the body of the trans.

I went to Napa today and they ordered the "part"...$1.69.

I can't find a schematic anywhere....I'm hoping that it goes in from the outside and that it's something I can do......
with my limited brains and limited patience.

For a long time, I was "chasing" a brake fluid leak. Right now, there are only two fluids in the truck...oops...three including the differential.
So, as I chased an elusive brake fluid, the trans fluid was fooling me. 65 and I STILL can't tell one from another. Even when brake fluid is so caustic.
What the $#&^%@?

Anyway, any tips on the trans shifter rod seal removal/replacement?
