Mark,
I second everything SoMnDMAX said. I also installed my Allison deep pan this weekend and heard no humming or whining afterwards. I hope it went away after a short while.
I don't know why, but I ALWAYS spill fluids when I work on the truck. Even with a Fumoto valve, I'll spill from the filter or something.
This time I was gently twisting the tranny pickup assy. off and it popped off and soaked my Polo shirt (dumb idea) and hair. I just happened to remember a few adjectives I learned in the Navy, but had forgotten for a while. Oh well, I needed a shower anyways!
The good news was even though I've been driving it like a 16yr old with a Mustang, the fluid was crystal clear, pan was clean, everything looked great inside.
Regards, Steve
