Hi There, The blinking D light indicates that there is a problem with the transmission. This may be something mechanical such as a shift solenoid or possibly some electrical such as a transmission speed sensor. This may also indicate that the transmission fluid may be low as well.
The rule of thumb is that if the check engine light is flashing, you can’t keep driving the car. It’s an emergency. Often it indicates an engine misfire. If you keep driving, you will likely cause irreversible damage, mostly to the (expensive) catalytic converter.
The D4 flashing light implies that there are potentially-serious problems with the transmission, so action should be taken quickly, either by inspecting the problem yourself or visiting a trusted mechanic. This will not only save you money in the long run, but it will also keep your car running for longer.
If the check engine light indicator is a steady light, you should schedule an appointment with your mechanic to get your car diagnosed and repaired. If the check engine light is flashing, then the matter is likely urgent; consider getting a tow to your trusted mechanic.
A flashing CEL indicates a severe problem, one that requires immediate car repair. In other words, if your check engine light is flashing, pull over and call a tow service. Continuing to drive your car with a flashing CEL can cause irreversible damage to internal components.
What does D4 D3 2 and 1 mean?
The D4 is a normal range in which the transmission shifts and uses all 4 gears. The D3 is moved to fourth gear, which is great if you need to change leg gears to climb steep hills. 2 allows only the first two speeds and 1 only allows the first speed.
What does a shift solenoid do?
A transmission shift solenoid is what controls the flow of transmission fluid. … It will determine the ideal time the transmission should be shifted and the control unit will send power to open the shift solenoid to allow transmission fluid to flow into the valve body.
Can an engine misfire fix itself?

If you turn the key to the ON position (or key in ACC position) but do not start the engine, you may notice the check engine light flashes 10x times. This happens if you recently disconnected the battery or used an OBD-II scanner to clear the codes.
If it blinks five times, the readiness
set, the test cannot be completed. So, at some point the readiness codes were cleared.
Can low oil cause misfire?
While what happened is interesting, going a long time between oil changes won’t cause a misfire. A misfire is an electrical problem, something caused by an oil problem is mechanical. As long as the oil level didn’t drop to some dangerously low level, there would be no mechanical problem.
What does it mean when the check engine light flashes 3 times?

D3 can also keep the transmission from cycling between third and fourth gears in stop-and-go driving.
Is it bad to drive in D3?
actually no damage at all. For my car to cause damage driving around in third gear (5 speed manual) I’d need to be doing more than 90, and in the equivalent gear to your third (my fourth) I’d need to be doing around 130. Depending on where your redline is, you’re likely higher.
