I'm going to ask you guys, too; I have a '94 GMC K-1500 pickup truck with a 5-speed manual trans.
What, besides GM's fluids, should I use when I change the transmission, transfer case, and front diff fluids.
Keep in mind, my region has temp ranges from +100 down to -40. I do light towing, though not long distances, generally. Mostly, the truck drives around town with the occasional excursion to somewhere else. The towing is done in town, but am considering pulling a trailer with a 1100# load next summer for a total distance of 350 miles.
I'll continue to use 80W-90 in the rear diff. I'm concerned if the electric actuator will be able to function in the front one with the same grease.
