M5OD Rubber Plug Replacement
My M5OD is leaking at the rubber plugs that are known for leaking. Can these plugs be replaced without dropping the transmission or removing the interior carpet?
I just put a new carpet in my truck and it took me a while to get it to fit just right so I really dont want to pull it up.

Rolling the carpet back will be the best decision. You can get it back in probably nicer now that you know the tricks. I didn't like the metal plugs most are using so I cleaned my rubber ones good and put a GOOD coat of sealant around them and it has been leak free. While you do that you can drain the fluid and replace it easily with the trans cover off. You might be able to reach up there from under the truck to access those plugs but I doubt you could see them well enough to do a proper seal job. I wouldn't attempt it that way. Also check the wear on your shift forks and replace them while you are in there if needed. Reuse the current gasket after cleaning it. Sandy

Here's a writeup I found while doing some research. Seems to be simple enough, yet I'm still dreading the day I have to tackle this project.

Yeah, it's simple. Biggest thing I found is go to the carwash and vacuum the hell out of the carpet first. You won't believe the crud that's in there.

Yes and Yes. 10 bolts to get cover off to do the job properly, and the rubber gasket will be fine also. Just wipe it off. You don't need to replace the rubber plugs plus they are not available new. You just seal the old plugs good with RTV after cleaning them up. Put the trans in neutral before you pull the cover and set the parking brake. Sandy

As for the plugs, why not get the metal freeze plugs that are available for short money? That's what I did several years ago and no leaks since then.

So I changed the fluid in the transmission yesterday and it was plenty full, in fact a small amount of fluid ran out of the fill plug when I opened it, so I guess they aren't leaking after all. The fluid on the side of the trans must be from an engine oil leak or something. I think the rear main might leak a little but the engine oil level doesn't seem to drop on the dipstick. I'll keep a close eye on all the fluid levels for a while just to make sure everything is ok.
