Engaging the Tow/Haul Mode doesn't eliminate OD from being engaged, at least my truck doesn't. Hitting the Manual button does, regardless of Tow Mode. Have you tried that? I mean, when you are traveling at the higher rpms that are bothering you, switch to Man, then back to auto. And then back out of the gas almost all the way to see if the final torque converter lockup can be achieved, because that is what is not happening if I've understood your post correctly; it has the final gear, just not locked in torque converter.TxCwbyUS said:I know that there is something wrong with my 2008 Nissan Titan XE ProX4.
With less than 800 miles on it, I can be driving along at 2000 RPM/70 MPH/and getting 16.8 MPH Average. When I stop... shut off engine... then restart the engine, continuing my trip, it takes 2450 RPM to keep me at 70 MPH, and then I am averaging 12.5 - 13.9 MPG Average on the Hwy.
95% of the time I am in the Higher RPM Range, this is not good.
When engaging the TOW button, which takes the engine out of overdrive, there is absolutely no change in RPM's, or feel of the Titan.
I took it in to the dealer, they hooked up their machine, but no code was given, thus they say nothing is wrong.
I KNOW THERE IS SOMETHING WRONG. WHAT CAN BE MY NEXT STEP? AND, IS ANYONE ELSE HAVING THESE CONCERNS?
All else fails, have a tech ride with you and the portable scan and duplicate it for him since no codes are posting. They have done this for me on the "cruise disengagement thump".
