Changing seal/O-ring @ trans. linkage?

[76jime]

Newbie here with a question. How do you change the seal/o-ring around the bolt that connects the linkage through the trans? Is it done from inside (removing the pan) or the outside. It's a 76/400 Jimmy with a TH350 trans.
Part #?
Thank you for your help.

Unfortunately I don't think you can get it out from the outside without damaging something. IIRC the valve body must be removed to get the manual shaft out of the case.

you can pop the seal out with a screw driver and then use a socket to seat the new seal it is not very hard at all and does not requrie tearing into the tranny

From the picture, that seal looks like it would be LOADS of fun to try to dig out with a screwdriver...

if you can't get to it with a screw driver you can take just the shaft out and not have to remove the valve body, when the pan is off remove the clip that is on the shaft then remove the nut. the shaft will slide out and it will be eaiser to change the seal.

OK, I'm going to take the pan off and remove the shaft from the inside. More work, less risk. I'd hate to gouge up the trans. case removing/installing a $3. part.
Thanks again for the help.

You can buy a tool specifically for removing that seal...makes it tons easier, especially if its in the truck. Maybe even try "borrowing" one from a trans shop - they are small enough, and can't be expensive.
