The transmission pan on my 05 frontietr corroded through, leaking about a dinner plate sized pool overnight. I have a pan on order but in the meantime is there some kind of goop I can slap on until then? Even better can I by some miracle make it controllable until spring or may it gush out at some point? I d like to believe that the oil seepage will prevent further corrosion.
 
The problem with attempting a temporary repair is the area has to be clean and oil/ATF free. That means sanding it and removing the oil, once you sand it to prep it, it will leak more. You can try cleaning the surrounding area and not the rust itself. Get a piece of lead flashing, and JB weld the flashing to the cleaned area of the transmission pan, making a tight seal, and keep your fingers crossed and hope it doesn't leak, or leak worse.

Several years ago I repaired an oil pan on my Aerostar [thanks to member eljefino] using this method. But I was able to allow the oil to drain overnight before cleaning the area and applying the JB Weld. You don't have that luxury unless you drop the transmission pan, in which case you could probably do a much better repair until you get the replacement pan.
 
If enough ATF leaked out to damage the transmission you are looking at several grand in repairs. Your counting that you know the rate of leakage and it will not change. Thats not something I would be comfortable with. Your in ME, probably already very cold. If you cannot put on the new pan when it arrives, pay someone to do it. Not even sure I would drive the vehicle until it has a new pan.
 
Smear a big patch of JB weld and window screen over it...

But it has to be 100% oil free to stick.

Just go get another pan from a trans rebuild shop

That really is the best way to handle it. There is no way to get all the ATF out w/o dropping the pan, and any repair done to the pan is a hack job at best. In the case of my oil pan I was able to allow it to drain overnight, and planned on junking the vehicle as soon as the replacement vehicle was at the dealership. So if it leaked out and destroyed the engine I didn't really care.

He didn't say anywhere the trans is damaged
 
I would be tempted to do a temporary repair as was mentioned by others.
Only you know how bad it really is.
This could work for one Week (max) until your 'new' pan is delivered.

When the 'new' Pan arrives, I would change it.
Do you have a garage or someone who would let you use theirs ?
Use a Space Heater to keep your hands from freezing.
Take it one step at a time and do a good job OR you'll be redoing in the Spring.

I would also use a good quality Rubber Gasket.
NO Silicone/RTV Sealant because it may not setup correctly.

I always coat my Engine & Trans Pans with Fluid Film.
Read other threads on here about Oil Undercoating.

Good luck.
 
Early 2000's Ford Trucks had oil pan corrosion problems that cost big bucks to replace due to the high labor hours to remove/replace the pan. Someone came up with an epoxy/polysulfide repair that could be accomplished without removing the pan and it lasted several years. You can Google this to get some ideas.

I might be tempted to try this Permatex product: https://www.permatex.com/products/adhesives-sealants/permatex-spray-sealant-leak-repair/ .... In order to get the pan squeaky clean, you would probably have to drain the fluid, then apply a shop vac to an access port to develop negative pressure and eliminate any leaking fluid. Just an idea. I don't know your situation and if this might work.

I was making the point that if he miscalculated how fast the ATF was leaking and lack of ATF caused transmission damage, the $100 to $200 he might pay to get the new pan installed will seem cheap.

When I was a kid old men used to tell me "close your mouth, open your ears". Now-a-days I find I am the one telling them to shut up and listen/read.

Too bad you didn't listen, high and mighty one.
