Cracked 4l80e bellhousing
Hello,
I recently pulled a 6.0/4L80e from an otherwise stock truck with the intention of putting the 4L80e in my Camaro. It's a 2wd 2005 Silverado 2500HD. While planning my attack, I saw several cracks in the bellhousing. After getting the transmission out, I noticed two of the ears had broken off. I have a TIG welder and plan to fix it, but I have several questions:
What would cause this on a completely stock truck? Nothing seemed out of the ordinary when driving the truck around...
I plan to put this behind a turbo 6.0 - is welding the bellhousing going to be an effective repair? I have been searching and see that some people have welded bellhousings, but none at this power level.
Any help would be appreciated.

I've heard the weld is stronger too, but I read online somewhere that aluminum is different.

It will weld just fine and as long as you are a fairly decent tig welder it shouldnt be an issue. I always bolt another bell to them when I weld them so everything stays put. I use a removable one off a 4l60e it works well and is very light and easy to manage...

I dont know what the cause is but I have seen that a whole bunch on the newer 80's that are bolted to the back of the 6.0L engines. I am not sure if its a corrosion issue or what. Maybe one of the 80 gurus will chime in and enlighten the "class"

Put a Reid bell on it I get my adaptors for like 80$ including all bolts and then get a Reid bell and bolt it on problem sorted then do the transgo kit till it smokes then have it built up and you will have a killer box!

Samething happened to one of my cousins in his truck. One of the bolt in positions of the case cracked to where it wasnt bolted in from one of the bolt in positions. They started to feel vibrations soo they took it to a performance shop and ended up finding out the tranny was loose from all bolts lol
