Hey guys trying to figure out how to remove the drain plug on a transmission. A previous owner couldn't get it out and after several methods grinded it flat. Only think I can think of is welding a nut to it and wrench it. I can't get a good weld on it though for some reason. Any other ideas? Picks to follow.

if the 17mm internal hex is still present you might be able to use a 3/8 internal pipe wrench to bite and remove it. 3/8 pipe is essentially 17mm OD.

I've had to get lots of help to remove some of the screws from the spring plates in the brakes. Typically, the last resort for this is to do what you're saying and weld a nut on then use a wrench to remove the screw. Anyway, at the beginning of figuring that out we were having a lot of trouble with getting the nuts to "stick" to the screw. Two things helped: use an older nut that has the plating mostly worn off. Of course, clean everything up really well with brake cleaner, too. The other thing that was not as clear was that we had to use the largest nut possible. Too small and the weld sucked.

Good luck

Got it!!! Sucker didn't want to go. Drilled a dimple on the edge of the circle and took a punch and beat on it for a bit to rotate it. Same idea as remove the lock ring for the steering rack.

Going to buy 2 new ones and put a small amount of anti-sieze on them. Any one find plugs without a 17mm allen on them? Maybe a standard male hex?

years back someone found a male-hex plug of suitable size from a BMW, search for it

sounds good, appears to be a M24x1.5 tapered. I'll see what I find and maybe post it in here for others.

Found this one:

stainless in aluminum - use antisieze!

Here's an aluminum option, though I trust the BelMetric one more, probably:

The originals are steel correct?

I like that one as well. Prob going to try it as it has a magnet as well on it.

Congratulations getting that f*cker out!

Some BMW manual transmissions use the male hex. Maybe start with an early/mid 90's 3 series?
Dunno about the anti-seize tho. Teflon tape for me...
For years, never had an issue installing or removing, or with leaks.
Then suddenly the trans oil started leaking past the threads. Coinciding with the arrival of synthetic gear oil?
Teflon tape to the rescue.

@Nowanker : Wow, I really like that idea. That one's going in the brain bucket for future use. (No sarcasm, I really think that's a genuinely great idea)

Cheers

Looks like BMW part # 23117527440 might be the one.
ECS has them for $13.
