Transmission Drain Plug “Rotten”

“2mchfun”, thanks for your comment. Not sure what angle you are looking for? I’m trying to show the condition of the plugs, and commenting on the shape of the pan and raised drain plug which will keep a lot of old oil and debris in the bottom of the pan if drained from the drain plug only. I think both my points are well represented by the photo.

If you look earlier in this thread, “Joe333x” posted a picture of the internal structure of the pan. “Koditten” suggested that the pan would need to be removed to get all the oil; that seems like a good idea given how much oil and debris would inevitably remain in the pan otherwise.

I’ll have to ask if removing the pan is part of the transmission fluid drain/fill services at the dealership. In my original post, the dealership declined to perform that service based on the condition of the plugs and replacement plugs not being available.

Koditten-I hope you are right and those plugs clean up easily. I’ll let you know what happens. Since I now have replacement plugs, I’ll hand them to the dealership to use if needed and request the old plugs back to check the condition myself.

Thanks everyone.

 

If you think those plugs are bad - wait til half the bolts holding the pan break off.

 

Yes, one can see the condition of the plugs in your photo. I just wanted to make sure you weren't getting confused on the location of the fill plug since the overflow plug appears to be slightly elevated due to the camera angle. As already stated by others, not much wrong with servicing that transmission as is. In fact, I wouldn't return to the same dealer who basically lied to you in the first place. If they can't work with some slightly rusted plugs, no way are they even close to being a capable mechanic. You have been warned.

 

This!^

 

Just to add to this, the hose is 5/8” OD.

 

^this, I wouldn’t remove the pan unless absolutely necessary because this will definitely happen.
When my truck was 3 years old, I read about this problem on this site. I carefully removed all the bolts and replaced them with new ones with never-seize on them.
Hopefully if I have to remove it, the bolts will come out without twisting off.

 

As others have already commented, I wouldn't try dropping the pan, if your drain bolts are like that, you most certainly will break bolts. I broke one doing mine with very low miles. Here's my thread on that if your curious. https://www.tundras.com/threads/my-transmission-pan-adventure.110777
There is magnets in the pan to catch any large metal debri and there is a vacuum bag like filter for smaller particles.

 

Another option is to replace the factory pan, bolts, and gasket with an aftermarket high capacity option such as a PML or B&M branded pan.
