Where to put trans drain plug?

I have a '93 4L60 (TH700R4) and have decided to add a trans drain plug so the next time i have to mess with the trans I can reclaim the fluid a little easier. I can see where there might be some interference depending on where i locate the plug kit. Should i locate it on the bottom or would one of the sides be OK. Anyone have any experience in doing this? Just figured i would get some opinions before i just pick a spot.

The plug kits I've used (B&M and Motormite) project ~1/2" from the pan, more if you use the hex-headed pipe plug that comes with the kit. The first one I used got put on the bottom of an AOD at the rear, but I used an allen-head plug that didn't stick out nearly as far as the one in the kit. The rest got put on T-350's on the front of the pan where the factory put them in 1970 cars.

Neither way lets all the fluid out, but both ways let out enough so you don't pour it all in your ear when the pan tips. I won't put one on the bottom again, because if it hits something, it might rip out the bottom of the pan, and I'll have to walk home in a seriously foul mood.

You just need to find a flat spot on the side of the pan that has 3/4" or so of clearance before there's any kind of solid object on the inside. Drill a hole so you have room for the big hex-nut inside the pan, deburr the hole, then install the kit. My first try on the AOD ended up with the plastic "gasket" cracked, so the rest just got a dollop of Permatex #2, and the plastic part went in the trash.

The pan on my 4l60e already had an "innie" dimple in the bottom that is for a recessed drain plug. I just bought the add-on plug kit and drilled a hole in it and welded in the plug bung.

So I'm saying there is a factory style pan - maybe deep pan or something - that has the location and recess already designed in.

The Dimple in the bottom of Pan is for the circular magnet that collects metal wear material. Not for a drain plug, all factory pans that came with drain plugs are on the side.

don't have a dimple in my pan, but i do have a square magnet. I really am leaning towards mounting the drain plug on the side. I will tape the nut inside the pan once the VB is back in place in an attempt to verify i will not have any clearance issues. I was gonna try drivers side towards the back first.

Newer Trans may use square magnets, I'm not sure.

Guys,

Thanks for your help, I ended up putting the plug on the passenger side of the pan between the accumulator and TV. I'll let you know if I run into any issues.
