Should you drive in overdrive on the highway?
Should you drive in overdrive on the highway?
Overdrive improves fuel economy, and makes for less wear and tear on the vehicle when you are driving at highway speeds. Having the overdrive off is fine if you are driving in hilly areas, but if you are on the highway, it is best to have it on because you will get better gas mileage.
What makes a transmission go in and out of overdrive?
But the transmission “decides” what to do based on what the engine is doing or what you are doing with it. E.g. a faulty brake light switch can make a transmission go in and out of TCC lockup. So too can a faulty throttle position sensor, or a vacuum issue or other things as well.
Why does my transmission whine when I shift gears?
If the whining noise seems to change with gear shifts or is coming from your transmission it could be an indication that it is time for new transmission fluid.
What kind of car goes in and out of overdrive?
Goes In and Out of Overdrive and burns up the Transmission! We recently purchased a 1991 Minnie Winnie (Winnebago) which rests on a 1990 Ford E350 chassis. It only has 58k miles. While driving on the freeway or highway, the Overdrive starts to go in and out; downshifting and upshifting willy nilly.
Can a transman go in and out of overdrive?
Transman, no, one can use overdrive where it is not shifting in and out most of the time. But if it is shifting back and forth, lock it out. In my state there are too many hills.
Why does my truck shift in and out of overdrive?
The truck has 115,000 miles. Mostly highway with no towing. Tranny was serviced (flushed) at 30K and at 80K. Fluid level is good and color is normal. The issue is it shifts in and out of overdrive repeatedly if I climb a hill or put load on it.
Why does my 4L60E shift in and out of overdrive?
The issue is it shifts in and out of overdrive repeatedly if I climb a hill or put load on it. It only does this at a narrow speed range at roughly 45-50mph at 1200-1300rpm. If I am driving faster (on the highway for example) and I hit a hill it doesn’t do it. All other shifting occurs normally during acceleration and deceleration.
What are the side effects of transmission shifting?
The most common side effect of this is a confused transmission and a schizophrenic TPS. Besides, a new TPS and a roll of aluminum foil is astronomically cheaper than going straight to suncoast to replace your entire transmission… especially if the new trans is just going to be fed the same confusing data as the old one.
What to do when transmission goes into overdrive?
Wrap the two smaller wires going to the alternator with tin foil as far up the harness as possible. Some have just twisted the two wires around each other in what is called a “twisted pair” for 8-10 inches back. Others have wraped the two wires with a small wire and created a shielded wire. The wraped wire must be grounded.
