hi i just got a 4x4 1500 auto 5.9 and i don't know if its normal for the rpms to drop immediately after i let go of the gas. it drops down to idle rpms. can someone help me out?
What do you expect it to do when you let off the gas? If the RPM's stayed up that's where I'd be worried. Your torque converter is just letting go and you're coasting. That's what it should do.
