was wondering what kind of leak would cause this



this has been like this for a while..i never see anything actually dripping from it but it usually appears moist

 

Is it transmission fluid?

 

i should have specified..it's a manual transmission...as far as i know it has never been changed...i am the 3rd owner of this truck (my dad bought it used years ago)...i checked the level of the gear oil level about 6 months ago and it seemed to be ok..i've been meaning to change it out but i have so many things to do on it it just keeps sliding down the to do list (new exhaust, tires, brakes, rotors, shoes, etc, etc, etc,)..this is one of a few leaks i need to address, i'm wondering what i was looking at..(i also have a rack and pinion leak, master cylinder leak, and a leak at the rear left brakes)

 

The fluid looks to be somewhat fresh. Do you have a puddle where it sits while resting? Do the old smell test. Grear oil, engine oil, R&P oil, coolant?
At least you've got it high enough, easy to slide under.

I love those Daks, had a '95, new off the lot. My stepson called a hour ago, the
water pump is leaking. (3.9). He has been running it since '05.
Had a '89, 3.9 also, wife's truck, sold it '04.
