I maintain 4 Toyotas, and all of them do this very thing.
I have learned to live with it.
I have taken them to Toyota dealers, who say there is nothing wrong with them.
I have taken them to independent transmission shops, who have changed the oil and serviced the transmissions, and they were not any better.
So now, I let the car warm up for a few minutes, and it shifts a little sooner.
God bless your efforts.
By default, your automatic transmission has a torque converter that is the main focus to your car\truck changing gears. I had one break on me in a Nissan Sentra and was glad I was close to where I was going because I would have otherwise been stranded.
If you live in a mountainous area and do a lot of traveling going up and down hills, your best bet, as long as you are above 58 mph(like going thru Denver on Interstate 70 and going west thru the Rockies, then it is okay to leave the overdrive on. I would, however, recommend that going up an incline of more than 30* then you may want to turn it off until you have reached a sustainable speed. If you are towing more than 800 lbs on a trailer on an incline of more than 20* then you would want to turn the overdrive off as the torque converter putting your vehicle into overdrive with a heavy load can cause the converter to snap within the transmission and you would be dead in the water.
If you live in a more plain-like state then the only time you really NEED to turn off the overdrive is if you are hauling a large amount of cargo any real distance or rarely get over 4300 rpm due to such short traveling distances. Overdrive function is primarily used to cut down on the amount of fuel needed in order to take long journey on Interstate or State highways that allow for speeds faster than 55 mph.
Hope this helps.
Does this happen with the overdrive off or on? If it happens with the overdrive on, then suggest you try it without the overdrive and see if your indications change. The overdrive normally starts to operate in that range. While both are transmission problems the overdrive isn't as hard to repair.
check on craigslist.com they normaly have alot of motors and parts on there. go to there car & truck parts and when you search for your car, only search for nissan. youll get more post doing it that way
THAT IS THE OVERDRIVE IN THE TRANSMISSION
THE CAR MIGHT NOT WANT TO SHIFT TO HIGH GEAR OR OVERDRIVE SOME OF THESE CARS USE THE COMPUTER TO SHIFT IT TO OVERDRIVE AFTER IT GETS WARM THE THERMASTAT PLAYS A ROLL IN THAT WHEN THE ENGINE IS WARM THE LOOP IN THE COMPUTER CLOSES AND THE CAR WILL SHIFT TO HIGH/ OF THAT WON,T FIX IT THEN THE COMPUTER IS AT FAULT OR THE SENSOR IN THE TRANSMISSION IS BAD
I would start with replacing your tranny fluid. black is no good. your tranny should hold about 7 qts of fluid. The tranny fluid runs through your radiator to help keep it cool. If your thermostat is stuck closed your eng coolant won't circulate and the coolant will get hotter inside your radiator. thus making your tranny fluid hotter and breaking it down. After time it will turn black from getting too hot. Let your car warm up to normal operating temperture then grab your upper radiator hose. It should be very warm. If not your thermostat is stuck closed.
