Your transmission can be severely damaged if you drive while your D light blinks. If the light comes on, you should have it checked out as soon as possible. Until you can get your vehicle to a mechanic, only drive short distances if you have to drive.
Most likely an overdrive light blinking is a telltale sign that the transmission on the vehicle has gone bad and will need to be repaired or replaced. Oil Changes, Brakes, Batteries + more!
What does the OD light mean?
Posted: Jul 10, 2021. The O/D Off light will turn on if you switch the overdrive function off. The O/D Off light means that your vehicle has disabled the overdrive functionality and hence your transmission cannot shift to the highest gear to facilitate acceleration on an upgrade or deceleration on a downgrade.
Too much torque demand during deceleration can damage the transmission and clutch. Some overdrives act as an auxiliary transmission unit, and effect the ratio of each gear in the transmission, but the overdrive in your Villager is merely a fourth gear.

How do you fix OD on a car?
The O/D off button allows you to prevent an automatic transmission from shifting into those top gears in certain situations, such as when driving through rolling hills, going down steep grades and hauling a heavy load or trailer.
Is OD light supposed to be on or off?
When this indicator light is off, it means your vehicle is setting the o/d On state to allow you to accelerate over the limit again. Many people often mistake the O/d off state when the light is off. But the opposite is when its indicator light is on.
Should I have OD on or off?
For most driving situations, you should leave it on. This allows your vehicle to use all of its available gears including the highest ones. Overdrive maximizes fuel economy and keeps NVH (noise, vibration, harshness) at a more tolerable level. There are no downsides to having it on.

O/D Light Flashing Even When Tranny Fluid is Full
Make sure they also change out the tranny pan filter as well. If the flashing overdrive light continues, then a solenoid might of been damaged. Replace all control solenoids until the flashing O/D light goes away.
When you use overdrive gearing, your car’s engine speed decreases. Using overdrive saves fuel and reduces engine wear. Our gas-saving tips can help you use less fuel and save money.
Does turning OD off save gas?
No, provided it is engaging at the proper speeds. Overdrive is actually a higher gear that allows you to travel at the same speed with lower engine RPMs, thereby increasing your gas mileage. No, it actually burns LESS gas, and that’s part of the point.
Does overdrive make your car faster?
Whereas a vehicle will normally operate at lower gears with greater output and torque, overdrive inhibits acceleration and maximum power. The vehicle is considered over-geared or overdriven, making it so that top speed and performance are sacrificed for greater fuel economy and a more effortless driving experience.
What are the advantages of overdrive?
Generally speaking, overdrive is the highest gear in the transmission. Overdrive allows the engine to operate at a lower RPM for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway.
How does overdrive work in a car?
Overdrive as a definition is simply having a faster transmission output shaft speed than the input rotation speed of the input shaft from the engine. This means torque is effectively being multiplied in a positive sense so being ‘overdriven’, creating a more effortless driving experience.
How do you use overdrive in a car?
Is overdrive Good for hills?
When driving in hilly country, it’s a great idea to drop a gear or two, or deselect overdrive, to avoid continual up and down shifting, and to provide engine braking on downgrades. Overdrive, in your case, is simply fourth gear, the uppermost gear.
Use low gears to keep traction, especially on hills. Don’t use cruise control or overdrive on icy roads. Be especially careful on bridges, overpasses and infrequently traveled roads, which will freeze first.
Which gear is best for uphill in car?
If you’re using a manual transmission, use second or third gear when you head up a steep incline – and don’t change gears once you’ve committed to the climb. Failed Climb: Put the vehicle in reverse to allow for natural engine braking and keep tires turning.
