Not Kicking in to Overdrive...

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?

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.

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".

I'm going to agree with the above poster here, in that it sounds like your torque converter isn't locking. And it should at that speed. On the lower gears, you should be right at 2000 RPM at 70 mph. No more.

There are some times when I'm still on the gas, that it seems that the converter doesn't "want" to lock, and I'll just back out of the gas a little and she'll lock right up. And then, there are some times it will lock up as I believe it should. The computer controlled lock up with its "load sensing" isn't perfect, but the longer I've owned it, the more I've learned its little "quirks", and I would write a longer post, but I've reached my "quotes" quota! haha

Make sure the trany is in D. There have been some people with center console shift that kept putting it in 4th and never knew it. If not then take it to the dealer.

I HEAR YA ON THE ISSUE. I JUST GOT BACK FROM SNOWBOARDING AND DRIVING THE TITAN IN THE MOUNTAINS. IT'S ABOUT A 150 MILE TRIP FOR ME TO VAIL,CO OVER A FEW MOUNTAIN PASSES. IT WAS SHIFTING FINE HALF THE WAY UP. THEN I WENT TO PASS A FEW CARS AT ABOUT 75-80 MPH. THE MOTOR WAS TACH'IN AT 4,500-5,500 RPM'S. MY TRUCK WOULD NOT SHIFT INTO FIFTH GEAR. AFTER I PASSED I WAS MESSING WITH IT. I TRIED WIDE OPEN THROTTLE AND JUST LETTING COMPLETELY OFF THE THROTTLE AND EVERYTHING IN BETWEEN. IT WOULD GO INTO LOCK-UP IN FOURTH GEAR FINE BUT WOULD HAVE TROUBLE FINDING FIFTH GEAR. IT WOULD GO IN EVENTUALLY BUT NOT LIKE IT SHOULD AND DEFINITELY WOULD NOT GO INTO FIFTH UNDER WIDE OPEN THROTTLE. A BIT SCARY!!:eek:

AMOUNG THE GUYS WITH ME WAS OUR TRANSMISSION TECH FROM THE DEALERSHIP I WORK AT (CHRYSLER/JEEP/DODGE DEALERSHIP). WHEN IT STARTED DOING IT HE JUST LOOKED AT ME WITH A CONFUSED LOOK. HE HAS WORKED ON QUITE A FEW TRANSMISSION'S IN HIS TIME FROM ALL DIFFERENT MAKE'S AND SAID "THAT'S WEIRED". AFTER HIM ASKING ME A FEW QUESTIONS HE SAID "YOU BETTER TAKE THAT IN TO THE DEALERSHIP THAT AN'T RIGHT"(IT'S STILL UNDER WARRANTY 15,000 MILES). HE SAID IT SEAMS LIKE IT MIGHT JUST BE A VALVE BODY ISSUE BUT ALSO SAID HE WAS NOT THAT FAMILIAR WITH THE NEW NISSAN TRANNY'S. HE ALSO SAID THAT A FEW OF THESE NEWER FIVE AND SIX SPEED TRANNY'S THAT SOME OF THE MAKES ARE USING DO NOT SHIFT INTO FIFTH AND SIXTH LIKE A NORMAL SHIFT (WHAT WE ARE USE TO). BUT MAN THIS WAS RE****ULOUS. I COULD NOT BELIEVE HOW LONG THE TRANNY WOULD HOLD OUT BEFORE THE SHIFT. I SET UP AN APPOINTMENT, WE SHALL SEE WHAT THEY HAVE TO SAY.

DON'T GET ME WRONG I LOVE MY NISSAN BUT NOW THE NISSAN COMMERICALS MAKE SENSE TO ME, "COME ON NISSAN SHIFT"

With the engine and drivetrain fully warmed up and on a flat road, it should lock into overdrive after 38 MPH. Mine locks at that speed everyday.

Mine too, except its at 42mph. I have the 2.94 rear ratio, and I believe you have the 3.36, correct? That may be where the 4mph difference is. I say to you guys having this trouble, TAKE IT TO THE DEALER! If you are correct in what you are saying, then it is not right. Take it to them repeatedly if necessary. Oh,......it will NEVER find 5th or torque lock out under WOT!!! No vehicle with electronic controlled transmission will unless it has been doctored. It simply senses too much load and throttle pressure to allow that. There was an owner at my work who had his locking in 3rd under load and he was having to back completely off the throttle for a full second before reapplying pedal pressure to get it to shift. It finally did throw a code after repeated visits over this issue and they were able to resolve it.

No, I have the 2.94. A cold air intake will change the engine load somewhat.

Sorry, I thought that it was you that had done the swap out for big tow gears on a non big tow. Who was that?
