I did my first ATF change ever on this rig about a year ago (See "European Economy Car Caveman, Unfrozen") and I was not impressed. What I wanted was a drain valve! Dangit. I know B&M or somebody makes a kit that involves drilling a hole, but I wasn't sure if it was failure-proof enough, if I wanted to tighten it some more, would I have to remove the pan? Here in the Underground Lair of the Squankum, we have a general philosophy when it comes to the missus's vehicles: F*** LEAKS. She drives far and wide and is not enthusiastic about checking things.
So, my dream involved a Fumoto valve. I've been content with simple drain plugs for decades, but I decided to try a Fumoto on one of her cars, hoping it would encourage her involvement with O&F maintenance, and I was the one who wound up spoiled by them. (On her cars, which see the most miles and O&F changes.)
At a minimum, it will just remove the annoying SPLOOSH! tussle when dropping the pan for maintenance, and that's good enough for me.
Got a used pan, had a friend weld in some thicker steel inside, drill it, tap it, and... oops, pan warped. I made a few feeble attempts to push, beat, and hammer on the pan to get it back into shape, no dice. I started pondering building an elaborate rig out of thick layers of plywood and glue and screws to put in my 20T press to make encourage this thing back to something flat... and the price of that was on my mind when... I discovered in the fine print of the description of the above Dorman pan... it comes with a drain plug! And not a rubber one.
Pan overall seems pretty decent. Stamping steel and powdercoating it (both sides, they did, for some reason) seem within China's "core competencies", as bizspeak would describe it nowadays. (I would use the words, "Something they can't F up.")
Drain plug hole is 12mm x 1.25. Comes with a bolt. Had to clean it up a little so a copper crush washer would mate against the limited surface area I had to work with on the bottom of the pan where the hole was (that's why I didn't use Fumoto's felty paper washer) and the powdercoating got into the female threads on the inside, but I cleaned that out and everything screwed together just fine.
Now if I feel like draining just a quart every 5,000 mi or some weird idea like that, I can do it. It's a weird idea, but this vehicle had 200,000 mi on it before I became crew chief, and while it wasn't neglected, on the issue of the transmission, maybe it was, records are good but not complete. What I found in the pan and on the magnet the first time I did the job horrified me. (But I'm new to this stuff.) This time, about 38,000 mi later, not so bad. I dream of adding a spin-on filter mount in the return cooler line someday, maybe when the engine's out and I replace those lines anyway.
The only auto trans car of my own, of a certain self-regarding German car manufacturer, has a drain plug on the torque converter, too, and it irketh me that I don't have this feature on this big machine.
Here's what Moroso has to say about their fancy gasket:
Manufactured from 40 durometer rubber that is vulcanized to a rigid steel frame
The extra-strength design will not leak, blow out or get sucked in like stock or inferior quality aftermarket gaskets
Gaskets require no sealant, which allows for quick removal and installation of transmission pans
Rubber/Steel gasket outlast cork compsites to provide years of dependable service
Full 3/16" thick
I know that everybody in Dodgedom is very happy with the factory's reusable gasket. That gasket wasn't on this car when I started working on it. I haven't seen one, and it's just a few dollars less than this one, but I'm sure it's good, too. I just found this Moroso on the intartrons and fell in love. 1,000 mi later, it's dry, and no RTV tussle was required, hooray!
