Tranny trouble?
01 QC 4x4 only upgrades are exhaust and Air Dog. While cruising at a steady speed rpms will bounce around like 1/4 or more at a time, this is happening more often. Then had a major spike in rpm while cruising around 45 mph it was like I hammered on the pedal but of course that wasn't the case. I have had the APPS replaced with an aftermarket from Genos Garage not sure if that could be causing this too. Truck has right around 97,000 miles. Thanks for any help
