Deep Sump Trans Pan Chevy Duramax Allison 1000

Everything went well. Some uncertainty with exactly which screw the rear support support bracket for the filter was supposed to go. A photo of that exact spot would have helped as three existing screws are there. The real problem was when I wanted to bolt in the new pan, I discovered BD Diesel had the wrong o-ring gasket in the kit. This one was about 5 inches too long. Discussed with the technical help desk, who sent out a new gasket, but I needed the pan back on and truck drivable that day. So I cut the o-ring to the right length with a 1/8" overlap at the joint at 45 degree angles. So far its working okay, no leaks. But lesson learned is check gaskets are correct before starting the job. So far it looks like the tranny is running a bit cooler now.
