It's not recommended to use overdrive on a constant base. It stresses too much the engine as well as transmission.
You should leave the car in overdrive at all times, unless driving conditions dictate otherwise. The overdrive is intended to optimize fuel consumption.
job done...motor comes out the top, leave the trans in place.
That means you are either in overdrive or you have a defect in the dash lights that is turning on your overdrive light. Wiki can explain what overdrive is better than I can, but it's not a bad thing. You should probably just leave your vehicle in overdrive for better fuel economy.
All you have to do is unplug the battery for about 10 minutes. That will reset the system, then drive the car or leave it idle for about 15 minutes. If it comes on again, then you have a problem and you should do a diagnostic test.
NO, leave the overdrive on. Only turn it off when pulling a heavy load or in a mountainous area. Overdrive improves your fuel economy.
Overdrive really wont affect you in a town or city, so you can just leave it on. On the highway, it helps reduce the strain on your engine, so just keep it on all the time.
Overdrive is the normally allowed position Until you are travelling around 50 MPH / 80 KPH it won't shift into overdrive anyway If you are towing something , or driving in hilly country where the transmission is always downshifting , then you can shut the overdrive off and the O/D OFF light will light up in your dash
yes. it will only shift into overdrive when it is needed.
1992 Toyota what? Corolla, Camry, Celica, Tacoma, etc. And what size engine. Not to be harsh, but how do you expect an answer when you leave out critical information, and even put the question in the wrong place.I moved the question to the Toyota section and I will answer when you provide enough information.
if it is an automatic leave it in overdrive. the transmission knows when to change into the overdrive gear. if it is a manual listen to the motor. if you have in overdrive and it bogs down while accelerating then down shift to a lower gear.
Overdrive is the normal position - if you are in hilly areas and find the transmission keeps shifting back and forth between overdrive and drive , you can use the overdrive cancel switch to shut off the overdrive feature and if you are towing something you also want to shut off the overdrive
