    Coolant Leak

    Does anyone have an idea about where this coolant leak is? I traced to dripping from the drivers side of the truck coming off the rear main on the transmission. It is very hard to see, but it is for sure Antifreeze. It is leaking enough to worry me and needing to get it fixed. Thank you in advance.
