Transmission Pan Painting Question

[Ncostello]

I have my pan off the transmission and had a 1-1/4" dia x 3/4" tall round machined piece beautifully tig welded to the bottom. I then drilled and tapped it to M14x1. 5 such that a Ram 1500 OEM ($4. 00) oil drain plug fits up. It has a nice seal already on the bolt flange and the tip comes up flush with the inside bottom of the pan. Looks real nice... almost factory. Overkill yes... but I like the idea I'm using OEM Dodge stuff.



Anyhoo... the welding process burned off the paint on the inside of the pan. That and buffing/sanding.



Should I just leave it, strip the inside and repaint, or just repaint the damaged area inside? I'm bead blasting the outside and repainting anyhow and could easily do the whole inside too. I just didn't know if Hi Temp paint would stick well with ATF on it constantly.



I doubt it would rust being in ATF constantly... but I'm not sure. At least Dodge painted it once and thought it would be OK.

I'd clean it and leave it alone. What you want to avoid is any possibility of paint flaking and plugging the filter.

It would have been better to start with a late model pan they are a bit deeper and do not need to be painted. I am sure there are many stockers going to waste after being replaced with a mag hytec.

I may end up getting a PMI or MagHytec pan eventually. But for 200K this pan has done OK and I really didn't have time to find another. I NEED to get this thing on the road But there was no way I was going to slap the pan back on this time with no drain!



I was on the trail I thought for a great deal. Mopar makes a "deep" steel pan with drain for 727's. Which will work on the A518. But from what I've read this pan is no different than my pan depth wise. Reason is I guess the A518 pan was made deeper than stock 727 pans. Rather... the Mopar Performance 727 deep pan "is" the A518 pan with a drain. And chrome if you like. And the raw steel pan is much more expensive than chrome. Go figure. Seems the A518 valve body is deeper than the 727. . hence the deeper pan. So if you use the A518 deep pan on a 727... you need a spacer... which Mopar provides.



I was really hoping the Mopar pan would work. Thinking I'd get 2 more quarts, bare steel, drain, $60. But it does no good. Its really intended for actual 727's.



Anyhow... I know there are alot of alternatives. I just needed a drain.
