I have an ATF leak coming from something directly above the tranny mount. I cannot determine exactly what is leaking. I have ruled out the trans pan (just resealed). Any things that commonly leak here?

tran output shaft seal. also check the seals at the transfer case sector shaft o-ring and the 4wd switch o-ring.

hmmm, my 4wd lights have not been working

do you know if autoparts stores carry the seals, or is it a trip to the stealership

the leak seems to be coming from the area right behind the shift linkage plate on the trans. there looks like there is a sensor screwed in there. which one is that?

that is the 4wd switch, there is a o-ring above the threads if the lights dont work the switch could be bad, but it doesnt come with an o-ring.

If the switch is leaking and not working it is probably because the bellows or diaphragm (or sometimes a piston) inside has blown and hydraulic pressure is on both sides of it. That will stop the action of the switch and it will probably leak through the not totally sealed outer housing of the switch, and it will happen to almost any pressure switch eventually.
