My stock pans flanges are in pretty bad shape and I would like to have a drain on the pan, so Im considering an aftermarket pan of which there are a bunch out there.... But with the cross member coming over the pan and the deep 'bump' on the 4x4 models, its really hard to tell which one will fit correctly... Mine would be the one on the far left..... any links or anyone else find a good fit ??
Yes, im definitely considering welding in a drain plug, just figured I could kill 2 birds with the flanges and bolt holes being pretty well banged up.... thanks for the info ND and the link Uranger Ohhh an that kit is a drill only, no welding.... very nice
Wheres the ideal spot for the drain add-on ? My local parts store actually has the trans drain kit, if you can believe it With the extended pick-up tube nearly touching the bottom of the deep sump pan etc etc.... Gotta do some net searching, im sure someone has this all figured out
Be careful with some of the aftermarket drain plug kits; some have been known to provide a chronic slow leak.
My situation was slightly different from yours. I have a '76 F-250 460 2WD C6.
For whatever it might be worth, here's what I did.
Purchased an aftermarket heavier than stock gauge steel pan to reduce the flange distortion problem.
Located the lowest part of the pan that wasn't over anything and didn't have any component close inside the pan.
Drilled appropriate hole for a purchased 1/8" NPT "bung".
Brazed the bung onto the pan. Brazing doesn't melt the parent metals yet results in a sturdy connection.
Slotted the inside of the bung flush with the inside bottom of the pan so all (most) of the fluid would drain.
Painted the outside of the pan and installed with double gaskets.
The photos were made with a flush hex drive plug to minimize distortion during brazing. The plug used finally was a 1/8" NPT square head with a magnet.
So far, no leaks, and it drains well.

Reason: more information
Thanks for the info Ozzie, I ended up using the 1/2" insert kit yesterday, let it sit all night and water tested with no leaks .... Didnt put it on the lowest portion of the pan, cuz I didn't want to interfere with the deep pickup tube on the 4x4 models... so I played it safe... I cheated and used a very small dab of Versachem #2 non setting sealant on the insert threads and nylon washer..... that stuff is amazing, Ive yet to have any fitting leak when using it... knock on wood...
