Trans Drain Plug...never a problem again!

Well, today was interesting. I was going to change the oil and then do a fluid change on the trans also seeing that I was going to install my B&M trans cooler. Well, I got under there and low and behold the prior owner had mutilated the drain plug bolt head something terrible (I just got this Tahoe 2 months ago). I tried everything I could but no luck. So I had to take the pan down the old fashioned way, full of fluid. Once I got it out and cleaned up I tried again to get the plug out but it wasn't going to budge. To solve the problem and never have to deal with it again I hammered a 9/16 socket on the damaged bolt head and welded it to the flange.....problem solved! The plug came right out. Now the next time I have to drain the pan, all I have to do is put an extension in there and take it out. This worked so good I may weld a socket on the drain plug for the crankcase on the next oil change. I got the B&M cooler installed with no issues and no leaks. What a day!

I use this for that issue.

That's an interesting idea. I've heard of welding a socket on to remove a difficult bolt, but I've never heard of leaving it there and reusing that bolt with the socket still welded on.
lol jesus christ. or you could do what I did and just replace the plug for $6 from the dealer, and don't torque it down like an asshole next time.

I didn't torque it down like an asshole......try reading the post. The prior owner did it. I actually have a new plug sitting on my work bench but decided I wanted to leave this one in because I plan on draining the fluid and changing filters often through the next series of oil changes because not knowing the full history of the vehicle I wanted to cycle the fluid in stages. And before I get blasted on that.......I am doing that based on advice from guys on here saying doing it a little at a time over a series of oil changes.
I'd be afraid of catching the socket on something, and loosing not only the pan, but all the fluid and burning the tranny up to boot.
If you look at the elevation of that short socket you would have to rip out the front suspension to catch the socket on something, there is no issue.

Oooh! Whoops! I totally missed that! ........

Still doesn't change what I meant one bit :high5:

same here.

I've got a Hughes deep pan. No problems now, but my factory bolt was a bitch too, never got it out.
