08 1500 High Idle Probs.
I have a 2008 Chevy 1500 LT 5.3L with the 4 speed transmission. Im not sure if its just the transmission only being a 4 speed but anytime I go 65-75Mph my RPMs are roaring at 2500. Other than that it shifts really smooth in lower gears and there are no codes coming up for the issue. I just feel like 2500Rpms is just way to high. Could my overdrive be going out?
