Default dorman tranny pans with drain plug

Anybody using one?

I bought a weld in plug of fleabay it`s like a pipe fitting and no matter how tight i torque it to it drips , even tried Teflon no bueno.
So im replacing it with a dorman unit, and was wondering is hot tranny fluid just to thin to use a drain plug?

I've never heard of aftermarket one one that didn't have trouble not leaking. It's really easy to drain the pan by disconnecting the tubing on the side before you drop it...... And given that you only do it a few times in the life of a vehicle ..... There's no need for the drain plug.... You got to drop the pan anyway to change the filter

Back before you could just buy a Dorman pan, we used to weld in drain plugs
You are possibly not using enough Teflon tape, or your weld is porous
Braze them in we did, less porosity that way

I had used the little two piece threaded plug off flea bay and it's holding tight so far. The 1\4 inch plug in a brass bush type.
I'm sure there's a way to make it hold.
Brazed in would be foolproof I would think

Well my welds are not porous and i did weld both sides of the pan.
I`m just thinking the reason the OEM guys dont do this is because of how fluid hot tranny oil is and will always leak?

The OEM guys (Ford et al. do it)
There are a bunch of factory Ford trans pans out there with drain plugs
They do not leak if done right / welded right

I have been using an ATP pan w/drain plug for seven leak free years. At the time, I felt the ATP was a better pan than a Dorman made one by the weight provided by each manufacturer.

The ATP was a little deeper than the original, adding almost an extra quart of fluid.
