that's mighty peculiar, I haven't seen one without it. But there's also not really anyplace for it to go. maybe it went missing during a former oil change?

i vaguely remember this problem from the fluid change last summer. no way of fixing it at the time. should have left a note for myself. anybody know of a place to get one? advance doesn't carry them, so its a safe bet the other chains don't either.

Im sure the dealer can get you one for a couple bucks. You could order it online but but paying for shipping would be silly.

i agree. i'll stop by one today. if it is outrageously priced, i found this one on amazon

Not all dealers are inflexible with their prices. My dealer actually has matched internet pricing a number of times for me. Just ask nicely if they can sell it for $9 because you found it cheaper elsewhere. If all goes well you should be walking away happy.

Or rip open an old hard drive and use the super strong rate earth magnet. I use them everywhere, including on the engine oil filter to trap fine particles.

You just assume everyone has old hard drives laying around. Lol

you know, i probably do have one or two lying around, but it would probably be easier just to go to the dealer instead of finding them. they said it was $11, so i'll go ahead and grab it. now i get to look forward to dropping the pan again next week. do you guys have a pattern for tightening the bolts? 1st time around, i went in a circle. eventually it started leaking. this last time, i made up a cross-pattern to try and tension it evenly. looked underneath this morning and saw a little fluid. 3rd time's the charm, maybe?

I usually go in a crisscross pattern in small increments and not over-tighten the bolts. Make sure the pan mounting surface is flat and that the bolt holes have not been pushed in, indicating that they were previously over-tightened.

well, did the repair on friday. the magnet is much smaller than i expected.
but i still have a small leak out of the pan. i've let the truck sit since friday evening. hoping the gasket and sealant have set and the leak goes away. this is getting old.

Did I read right that you used a "sealant"? Tranny pan gaskets are installed dry.

Is your leak out the drain plug or around the pan. My dorman pan needed a plastic gasket 65270 part number.

Definitely the problem. Only use one gasket type.

Perhaps you were thinking of cork gasket adhesion compound. It's a tacky substance used sparingly that keeps the gasket in place while you torque the pan down.

However with our stiffer neoprene gaskets it's not necessary. You just start a bolt in each corner and the rest should line up without any finagling.

used the stuff at the counter at aap. don't think it was permatex. maybe more generic, but the same kinda stuff.

Could have been an old style shellac. Anyway, tranny fluid has a high amount of detergents and eats through this stuff. You have to check the pan mounting surface for flatness on pane of glass. The neoprene rubber gaskets that are used in these trannys are leak free if it's done right. My truck's pan had elongated bolt holes from a previous owner over torquing the bolts. I was able to hammer them back down and I haven't lost a drop since.

I used the high temp form-a gasket (the red one) and put a small amount on my gasket to hold it in place.
I've had no issues.
I'm getting ready to drop the pan and install my new dorman pan with the drain and a tranny cooler.

or maybe i'm just jinxing myself. the culprit seems to have been improper torque specs on the mounting bolts. they were way looser than they should have been. I guess next time i'll clean the oil off my screwdriver-type socket wrench. I got tired of my hand slipping and figured it was good enough - which technically it was since i could drive the truck. it just wasn't right. I've never had a problem just tightening bolts by hand and not worrying about how many inch-pounds or foot-pounds are needed. until now. a torque wrench is your friend.
