The small sun gear freewheels, and the larger sun gear is held by the overdrive band.
Turning off the overdrive is basically preventing the truck from shifting gears past 3rd. It's useful when you're going up or down steep hills. answer Dodge Ram trucks come stock with an overdrive, or O/D, function that enables them to switch between three and four gears. When the overdrive is off, the truck operates on three gears, allowing it to pull more weight and giving it more power. When the overdrive is on, the truck operates on four gears, using less power and less gas.
I have 1987 magna elite automatic the overdrive button when applied does not engauge , however all other gears are fine and operate . What may be the diagnosis please affa
Overdrive just lets the car use the lowest gear. Without overdrive you are probably only using 3 gears, and with it you are probably using 4.
On a 1998 Ford Explorer, Overdrive Band Failed Off means that the vehicle did not shift into Overdrive properly. The band for this gear should be serviced soon.
It could have 3 forward gears or 4. Some automatic transmissions have overdrive. Overdrive is another gear that allows for better fuel economy on the open road.
If you have an automatic gearbox, 4. Plus two extra overdrive gears, in 3rd. and 4th. gears. The total will make 6 different gears. European Volvo 960 with 2.0 liter turbo engines have manual transmissions with 4 gears plus manual overdrive. The later S90 was also available with 5 gear manual (reverse was synchro!)
Select the " D " with the circle around it for overdrive Select the " D " if you only want to use the first ( 3 ) gears and no overdrive

Three plus Overdrive
Three. Or (with overdrive) four. Plus reverse, of course!
You have to use it when you are driving in mountain areas where to have high speed is not a good idea. The overdrive function does allow the transmission to switch to higher gears.
when ur driving in the city it is adviced to put gears in drive rather than in overdrive position..the reason being overdrive is a system that allows your gears or drivetrain to use the lowest gears /ratio for fuel saving cruising, with it off , it holds to a higher gear ratio so you have more power and torque to tow or climb hills..but it prooves to be horrible while driving in the city..
