I have an 88 f250 and i just got it back on the road a while ago after it sat for 6 years. I noticed that the front differential leaks, the transfer case leaks and something else is dripping off the tranny that i cant really pinpoint exactly what it is. It looks like engine oil but i am not low on oil. Am i going to need gaskets for the tranny and transfer case? How do i figure out the substance dripping off the tranny.

 

Well clean it all off first and check all the pan bolts for tightness. Then you can pinpoint where its coming from.
