Something put a hole in my transmission UPDATED w/PICS 8.12.2007!!
Hi,
I was at the local track last night, and something let go in my trans, putting a hole about the size of a finger through my casing right near where the shift linkage connects to the trans (LS hydro trans). I am pretty sure I can see the diff. now. The funny thing is that I didn't hear anything strange when it happened (apparently, it was right off the line because I oiled down the entire track!). I knew something was wrong when my cabin filled with smoke from the oil covering my exhaust. the car is still driveable, In fact, I put some duct tape over the hole and drove the car home, 50 miles away from the track. Every gear works fine, no noises, no nothing! So I guess my question is, what could have let go inside my tranny that would put a hole in it but not affect its ability to shift gears? (Mista Bone, help me out!). I'll try to get pics up later. Needless to say, I need an LS case, and who knows what inside, I'll have to pull it out and apart. It will be my first time inside of a transmission. Hopefully it will be covered in my manual. Anyone with a trashed hydro LS or just the case, PM me!
UPDATE:
I pulled the trans out of the car today and took it apart. This is what I found:

I have circled the hole in the case as well as what seems to be the cause of the hole. The reinforcement tabs in the case broke off and took others with them. I found the remnants of the aluminum bits throughout the case, mostly at the bottom of the case though. Although there is a fine mist of aluminum throughout the trans, everything looks pretty ok, although this is the first time i had cracked open a transmission. the only thing that creeped me out was the grooves present on each gear. I don't know if they are supposed to be there or not, although they are uniform, on the same spot on every gear which leads me to believe they were there from the factory (?). I have to search for more pics of these gears. I thought for sure something let go in the diff. considering where the hole in the case was. Here is one of the gears that I pulled from the mainshaft:
Again, you can click on it to enlarge it. You can see the grooves in the tips of the gears that I was talking about. Very uniform.
Does anyone know if these grooves are normal? If they are, I plan on either getting a new case or welding the current one closed and adding an LSD. This trans was great before this happened, no grinds at all!
Hopefully It can be saved...

I don't know jack about transmissions, but I am fairly confident that this one can be fixed, I drove it 50 miles low on fluid with no weird noises. I have to get it out of the car so I can assess the damage, but if most damage is to the diff, it won't really matter in the grand scheme of things, i'll just replace it with the obx.

It's obvious you didn't need whatever fragged anyhow.
