I don't think I'd put sealer in an automatic transmission. There are a ton of tiny little fluid passages in the valve body that control when and how it shifts. I'd be afraid it'd gum that up. Honestly if you have a cracked cooler line, the line will probably cost what the can of sealer will, or pretty close. As for aftermarket coolers, I dunno, pretty much anything should work better than nothing.
Sealer is a very bad idea.
I would top your fluid off and wait & see what happens. I don't think a leak is likely.

I'd bet it is NOT a crack or leak. Transmissions have a relief valve that allows fluid to escape when the trans is overpressured...as in very hot and under heavy load. I had a F350 dually Powerstroke do this once backing an RV trailer into a camping spot. Scared me. Took truck to dealer in Maine and a smart mechanic checked it out and told how transmissions are built.
It takes a lot of pressure and heat, but you can bet there is a relief mechanism in your (our) transmissions to prevent it from detonating under load.

The more I think about it, I have to agree. Especially if it seems to be working fine. Transmissions don't tend to work well if they are hemorrhaging, at least not for long. Still, if he's doing a lot of towing in hot weather up hills, this is a pretty good sign that he needs to get an aftermarket transmission cooler installed.
Something like http://www.jegs.com/i/B-M/130/70264/...oductId=758370 mounted in front of the radiator would work nicely. I'd also consider getting a tranny temperature gauge, not horribly expensive for the gauge and a single-gauge pod on http://www.egauges.com/

not 100% true. my tow packaged 95 did not have tow hooks or skid plates. it did have a factory wiring harness for a trailer and a factory hitch. it had larger brakes and a radiator with lines running to the transmission too

my 96 has no tow package.
It defintely has a trans cooller. there has to be a wat to fix those lines depending if that where its leaking from. I tototaly bent my 96 to the point where i have to open the back door to get the front open. the lower control arm mount is done. the upper arm smashed the cooler in and out lines against the side of the oil pan where they run. tubing tubing bender flare tool and compression fittings. fixed it. PS dont launch xjs without beefy control arm mounts. Or you will have to buy a 95 with new problems. lol
