Bell Housing Flashing
Without the gasket, the pan hits the mold flashing on my tranny's bell housing. I sanded the flashing away and rounded the edge of the pan a little. It probably would have been fine with the gasket though.
The cooling fins were hitting my UCF skid. I had a machine shop mill them down to the level of the drain plug surface. In hind sight, I may not have needed to.
Since I can't weld aluminum, I had the machine shop TIG weld the bung in. Since welding shrinks it a little, I ran a 1/8-27 Pipe (NPT) tap to get it back in shape. Aluminum is soft, so it doesn't take much.
I believe the angled side (where the corner is missing) is the best area to mount the bung. It clears the drive shaft and internal parts of tranny. I used Permatex High Temperature Thread Sealant (59214) on the sensor threads.
FYI, the machine shop wanted to know if the pan was new or used. If it had been holding fluid, they wanted to bake the oil out, which would have cost more money. Good thing it was new.
They welded both sides of the bung!
Mounting Surface Isn't Flat
Yep, again. I can see where the mill didn't touch one of the sides of the mounting surface. It's about 1/32" off. The machine shop said they couldn't get it held down well in the mill to deck it. So I was hoping for the best. Turns out it is fine!
Drain Plug Threads
The pan came with the drain plug screwed in, but only partially. They couldn't get it in all the way because the threads were slightly messed up. I wonder how that got by Q&A. I cleaned it up with a 1/2-20 tap.
When the dipstick is inserted one way it rubs on the inside corner of pan. If I rotate the handle 180 degrees it's fine. The casting has a texture to it. So I polished up that corner to prevent any aluminum getting rubbed off.
Also, know this. My dipstick would never stay seated in the tube with the factory tranny pan. It would pop out a little. With this deep pan, it stays seated. I have read other people have this problem too. I guess the damn stick is a little too long and after you quit pushing on it, it springs out of the tube an inch or so.
Here it is complete. The arrow is pointing to the polished area.
