Please fill out the following to ask a question.

MAKE:Chevrolet
MODEL:K5 Blazer
YEAR:1983
MILES:120,000
ENGINE:350 cid
DESCRIBE ISSUE....The transmission started leaking from the 2-4 servo cover after replacing the servo gasket and servo cover gasket it still leaks. Is there a certain way to reinstall the gasket? or could there be a bigger problem I'm not seeing? Thanks for the help.

I show 700r4 2-4 servo as a series of O rings - attachment.
Am I looking at wrong component?

The only other rings I saw were the flat metal rings attached. The only rubber seals that I had seen where the 2 that were replaced

The lasted one you sent was for the 4L60e. I'm wondering why it's still leaking from the same spot. It leaks from the 3 o'clock position from the cover.

I just remembered that. Sorry, I'might justhe frustrated. I had already fixed 2 leaks previously and then this one shows up.

one of the members here is our resident trans expert - he owns a trans business - He will see this and ad his professional insight when he stops by. Maybe some tips on installing the seals or what may have gone wrong...
Tell us what were the other leaks - maybe the big picture will help him get a better idea of what going on.

I had to repair the lower cooling line, because someone had tried to fix it before and flared the end cockeyed and I had to replace the grommet for the dip stick.

I will check the cover and the servo to make sure the gaskets weren't pinched. I'm just hoping the case didn't get cracked somehow.

Is there a way to remove the cover without ruining the o ring?

yes once you pop out the lock ring the cover should move to were you can get to the o ring with a small pick get behind the oring and pull it out some while rotating the cover and it should pop right out
