tranny pan

Get a HeliCoil kit they are available individually in all thread sizes. The drill size you need will be printed on the package. Take your time and follow the directions. Neoprene or composite gaskets are better than plain cork. A lot of pan leaks are actually leaks that start somewhere else and just look like pan leaks.

Mopar now sells a reusable plastic oil pan gasket with o-rings on both sides. It is a LOT easier to install too since it is molded plastic. It is about $11. Also, if you get one, make sure the sealing surface on your pan is good and flat.

Definitly take a look first and double check that it is the pan before you go through all that work. I made that mistake myself. I thought that my pan was garbage and kept resealing it and it was the dipstick tube o ring that was leaking.

Glad you posted that!

I agree with the helicoil, tube Oring, and gasket recommendations above, but there's one other factor I bet is part of the problem...

If you do the pan, look at it closely, and you'll probably see that the bolt holes are pushed in toward the transmission, because people have over-tightened the bolts...

Lay the edge on a two by four and center the ball end of a ball peen hammer on a hole (on the tranny gasket contact side of the pan lip). Tap gently to push the bump back towards the "outside"... Repeat until they're all better. Then, next time-

DO NOT OVERTIGHTEN the pan bolts !

sweet dude....that would have been hell to figure out. the guy that i bought the truck from seems to be the kind of guy who would just overtighten everything....only build it once....so that is most likely one of the problems.

Those leaky dipsticks are no fun.

Not really. I resealed the pan 4 times, plus I took it to a shop and told them to look at the dipstick tube because I thought the o ring was bad. They said" Oh, its in there nice and tight, theres nothing wrong with it". Needless to say, i'll never go back to that shop again. So when I rebuilt it thats the first thing I replaced, and guess what, it doesn't leak.
