Hello, 2015 F150 5.0 / 6 speed. At times I get a hard 3rd to 4th shift. Truck has about 170,000 on it, and shifts fine most of the time. I have put 130,000 of those miles on it and noticed the change in shifting I'd guess about 10,000 or so miles back. Fluid has been changed. I also here a noise that appears to be coming from the transmission at times when I accelerate hard (passing someone), that sounds like a belt slipping. I know that isn't the case, just the best way I can describe the noise. The noise may only happen a couple of times a week, and not reproduceable. Just wondering if anyone else has ran into these issues and found a simple fix. TIA.

 

Same. Sounded like belt squealing
