This one's new to me. I took Heavy out to pick up a friend. Today it had snowed, but it wasn't freezing cold today, maybe about 30*. The roads all around my house were covered in slush & I had a hard time picking up traction, so I put it in 4-hi. After the truck was warmed up, I got on the main road to get to my friend's house. I've got to admit, I had been laying into the pedal a little bit, but nothing extreme, just having a little fun. I just happened to glance @ my trans. temp gauge & it was borderline to 200*. I let off the throttle & the temp started dropping dramatically & landed on 150*. All throughout the ride, I monitored the performance; taking it easy, laying into it a little, normal driving, etc., & the temp fluctuates between 150*-180*. It wouldn't always increase
when I accelerate, no matter what driving condition. I shut off 4x4 & it didn't make much of a difference either. When I came to a red light, it would drop a click under 150*. Then I'd take off from the stop, & it would increase to over 150*, raise, drop, raise, etc. I got to my friend's house & let it sit for about 1hr. When we got back, the needle was under 100*. I had to put it back in 4x4 to get out of his parking lot & about 10mins. of driving, the needle started to fluctuate again. It would get back up to 200* & then do the same thing all over fluctuating between 150*-180*. The cooler doesn't appear damaged & it's not leaking any ATF, but I did noticed it's caked with slush & ice. I haven't check the sender for the gauge yet, but I figured if there was anything wrong with it, the gauge wouldn't work @ all. Has anyone else had this problem? Can anyone help? Before this happened, the needle would never go above 100* & now it's doing this. What's your takes?
