make sure you not in LOW Range 4-wheel drive
That could do it!
ALSO THERE IS A VACUUM LINE GOING TO TRANSMISSION THAT SOMETIMES GETS WORKED OFF. CHECK THERE AND THAT WILL PROBABLE BE THE PROBLEM
My f150 shifts from 2wheel to 4wheel on the fly, but to use 4low you need to be stopped with your transmission in neutral to engage the low range in my transfer case.
what are you wanting to take the transmission out completely or what?
i have a 200 f150 p/u if I put my foot into it it will accellerate and shift as it should until 60 mph. at that time it will over rev and I have to slow down and dissengage over drive.
the shift siliniod for AOD transmission is bad. it cost about 30 bucks and is usually special order
The transmission may shift hard due to it beginning to fail. However, it may also be due to low transmission fluid.
Check all the linkage from the transmission.
It's underneath the truck. It leads from the transmission to the diferential
When was the last time you changed your transmission fluid? As the fluid gets older, transmissions start to shift harder, and you notice the shifts from gear to gear a lot more. It could also mean that your transmission needs repair.
you have problems with your overdrive, or it may be a sensor on your transmission. I would recommend a simple transmission fluid change along with your transmission oil filter (it might be clogged) and a lot of times it fixes your sudden changes in gears.
Yes.. I Have a 1990 F-150 4X4 and it is a 5-Speed Manual Transmission
The switch is located on the driver side of the transmission. right where the shift linkage joins the tranny.
Basically it is 5th gear in this transmission. With overdrive on, it will allow the transmission to shift to 5th gear, which will let the truck move faster with less engine rpm's. More fuel efficient. If you are towing or hauling a lot of weight (over 1000 pounds), it is better for the engine and transmission to turn overdrive off.
