I’ve never done this myself. Aren’t the tranny pans on these GM trucks notoriously difficult to get off because of the exhaust pipe or something?
Nbs trucks 01-06 are easier than nnbs 07-14
Exhaust is tighter to pan but not that hard imo

Well- after more back and fourth I’m not doing an afm delete. Just getting a new long block that doesnt have afm, and its got a ‘step up cam’ for towing. Gonna have that replaced next week, have it tuned, and then I have to drive down to SoCal. Should be fun. Kinda down to the wire though.

once you have the pan out you can add a drain dorman sells a kit

On my last truck I just drilled and welded in a bung I bought off the rack at the local car parts place. It came with a gasketed bolt, just like OEM. Simple. Worked great.

The one you linked protrudes above the bottom of the pan, so it doesn't fully empty. If fluid still dumps out when I remove the pan, there's no point in the drain. And that nut doesn't appear to be a locking nut. If it vibrates loose, you leak fluid. If the plug has enough removal torque to overcome the retention torque of the nut, it spins, rendering it useless. It's a no for me.

Point taken, it has a drain bolt with a o-ring like a oil pan drain bolt which is smaller so it won't over torque the larger part of the adapter, not everyone has a welder :) it's a slow seller but no complaints from anyone.

What!?! If you don't have a welder, you should at least get a weldor (a friend who welds).

I wasn't saying it's bad. It's just not for me. I'd like it better if it used a prevailing-torque lock nut to keep it from loosening. You can't use thread locker, either. It'll make the sealing washer crack. Don't ask me how I know that.

Or just buy an aftetmarket pan that has fins or tubes to help cool the fluid and a drain plug in it. Then just punch a hole in your stock one and let it drain then throw it away after removal.

that's what I did I bought the B&M deep pan that holds 2 extra quarts, cast aluminum with cooling fins and a drain plug.

lol, if I need something welded I just go by any of the muffler shops or my preference is the hardware store/farm supply/machine shop/fabricator that has everything under the sun and if they don't have it they can make it, love that place. these guys >>> there like a harbor freight on steroids

20 minutes to change the suspension air comp. is BS.

Maybe on a brand new model. But on a 10 yr old with corrosion dirt etc.....

Let me just say it took 2 hours to get the old one out and i looked like a cartoon character after with the amount of sand grit etc in mi hair face etc.

Fuse is blown so I have to get a new one at NAPA tomorow...

Mine's 11 years old. :shrug:

Corrosion? Are you in MI or FL? I saw Naples and never considered rust a factor.
