You dont
Your Transmission Range (TR) sensor is a prime suspect. Return to shop that re-did your transmission and explain the problem. The TR sensor may be bad or just need adjusting.
Shifts the transmission in/out of overdrive Shifts the transmission in/out of overdrive
pulse generator is bad
I have a 1997 ford e 350 van with automatic transmission when the transmission shifts form 3rd gear to overdrive at about 50-55 mph it falters and bucks and I have to let off on the gas so it can pick-up speed, when I have overdrive off and put on overdrive when 3rd gear shifts to overdrive at 50-55 mph it shifts smoother but if I give too much gas again it bucks and falters till I let off gas so it can retain speed slowly.
My 1984 corvette transmission is not shifting into overdrive. It shifts first thru third fine.
If you are on a highway maintaining over 45 mph. OK, but If vehicle continually shifts in and out of overdrive you are better off leaving it in 3rd
Overdrive is the normally allowed position , but unless you are going fast enough it will not shift into overdrive because it acts as the " top " gear ( on my Explorer I have to be going 50 miles per hour / 80 kilometers per hour before it shifts into overdrive )
If it shifts smothly into the gears before o/d it is not the cable.
The button does not switch from Overdrive to Automatic. The button just turns the overdrive off. Overdrive is not a separate drive system as your question implies. Normally you leave the car in overdrive mode. That way the transmission shifts into overdrive at highway speeds, thus saving fuel. If you are saying the transmission is stuck in overdrive and it will not disengage then seek out a A/T professional.
four wheel drive low ========================================================= I know that on my Ford EXPLORER the automatic transmission shifts into overdrive around ( 50 miles per hour / 80 kilometers per hour )
According to the 1995 Tracer's Owner Guide (page 241): Overdrive is the usual driving position for an automatic overdrive transaxle(transmission). It works the same way D (Drive) works, AUTOMATICALLY upshifting or downshifting as the vehicle speeds or slows. However, Overdrive also shifts into a fourth gear (an overdrive gear) when your vehicle cruises at a consistent speed for any length of time (like on the Interstate). Overdrive will increase your fuel economy when you are traveling at cruise speeds (usually 50mph or higher). But, Overdrive may not be appropriate for certain terrain such as hilly or mountainous roads because the transaxle (transmission) automatically shifts back and forth between 3rd and 4th gears while doing this type of driving. Therefore, it is recommended if your car is continously climbing hills/mountains (which requires additional power) then you should shift to D (Drive).
Mine has the same problem. The transmission guy said not to worry about it.
