Transmission worthless?

[dc9137]

Well...I've had a pretty discouraging weekend. As part of my rebuild, I pulled the engine and transmission today. I've never done it before so I was pleased with myself for getting it done without breaking anything, but I was not happy with what I found.

First, I'm pretty sure they just threw in an old engine and transmission at some point because it was just barely attached. None of the exhaust was bolted on, most of the fittings were disconnected and all of the bolts were pretty loose. I was planning on rebuilding it anyway, so I wasn't totally upset by it.

The transmission on the other hand...One of the mounts on the transmission is completely broken. See attached pics. I'm afraid this means the transmission is useless to me without a new case. Can someone with more experience weigh in for me?

If the engine is as bad as I think and I need a new transmission, my project truck may get turned into a parts truck and I'll be on the lookout for something in better condition.

I would not think that would make a big difference for just one. There also may be a way to fix that if you know someone who is skilled in metal fab.

Don't worry about it. That one broken ear will not hurt anything.

not a problem

you still have some part of the mount left. just put an oversized washer under the bolt when you put it back togather.

I have an exhaust manifold bolt on my cummins 6bt in my motorhome that basicly did the same thing, I put a little bit bigger washer under it and it has been ok for about 10k miles. and thats on an exaust manifold that gets real hot and also has an exhuaust brake and it has held up.

The transmission currently mounted to my M1008 has an ear broken off in a similar manner.

As was mentioned above, I'd just use a suitable washer on that bolt when you reinstall it... Replace the transmission later.

A good welder can repair that. He can build it up, then you can drill a new hole.

Thanks all. That definitely makes me feel a little better.

Certainly. Aluminum castings are easily welded. 4043 is the correct filler metal.

Have it welded up if you want the best fix.

Quick and almost as good fix would be the oversized washer (ground to fit).

Just run it as said with a washer. Dont waste time or $ getting it fixed. You will be fine.

My M1008A1 came with only 3 transmission mounting bolts. Two were loose. No idea how long it was run in this fashion, and I put almost 700 miles on it this way before discovering it.

So, chances are you will be just fine with a bolt/washer combination.

Having said that, you asked for opinions. If it was a truck I wanted to keep in the long run, I'd have the flange welded while the tranny was out of the truck.

One of mine is broken too.

While you have it out it is a easy fix for any weldor put a bolt or rod the right size in place and add metal till fixed then remove bolt and clean up the area.

It's already been said but if it's just one bolt, no problem. Any decent shop can fix that.

Good Luck!!

Just to make you feel even better than the advice already given. Chevy eliminated that bolt behind the #8 cylinder with the 2000 model year engine. Everything since doesn't have that mount even there anymore. You are fine.

but yes one ear wont hurt and enough of it is still there for the bolt to catch.
