The D4 light is not only a gear select indicator, but a malfunction indicator for the powertrain control module (PCM). If it blinks as you describe, the computer has detected a fault in the system and has stored a code(s). The diagnosis procedure is no different than it is for checking the ECM trouble codes.
What does it mean if your D4 light is blinking?
Problem Description
If the transmission shifts roughly, the failure is very likely mechanical failure of the transmission. If the transmission performs normally, a faulty sensor, or dirtytransmission fluid may be the case.
Why is the drive gear light flashing?
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.
What is the difference between D4 and D3 in a Honda?
D4 is the “normal” automatic transmission mode and uses all the gears. D3 is very similar except it does not engage 4th gear, only gears 1–3 are used. 2 is 2nd gear and 2nd gear only, no 1st. Best used perhaps when the road is slippery or another similar situation when being locked in second gear would be beneficial.
Do Honda Accords have transmission problems?
Honda Accords have been known to down-shift erratically, sort of jumping and skipping into place. In some cases, the car may even come to a complete stop out of nowhere. These problems usually start to pop up after 100,000 miles on manual-transmission Accords. Once again, you’re looking at transmission failure.

What happens with low transmission fluid?
When your transmission fluid is low, your car won’t generate as much hydraulic pressure, leading to what’s known as gear slippage. Gear slippage commonly manifests as a failure to accelerate properly. When your transmission fluid is low, you may notice your vehicle reaching high RPMs while moving sluggishly.
How do you check transmission fluid levels?
Check the Level
With the engine warmed up, leave the car idling in park on a level surface. Pull out the dipstick, wipe it clean, replace it slowly, and then pull it back out. Check the fluid level—how high the fluid comes up on the dipstick—against the “full” and “low” or “fill” marks on the dipstick.
What does a flashing D mean on a Honda Pilot?

Does D4 use more gas?
Registered. D4 unless your going up a hill and it keeps shifting between the two, then put it in D3 till you get up the hill. Otherwise it will use more gas as it is almost always running at higher RPMs.
What does D4 on a car mean?
Drive (D4) — Use this position for your normal driving. The transmission automatically selects a suitable gear for your speed and acceleration. You may notice the transmission shifting up at higher speeds when the engine is cold. This helps the engine warm up faster.
Which is faster D4 or D3?
It is best to use D4 on the highway when driving at speeds above 40 mph or 60km/h. There is usually less braking on the highway; hence D4 provides a faster speed than D3. It is better to drive at D4 when traveling outside the city than to use D3.

Why do Honda transmissions fail?
The most common cause of failure in a Honda automatic transmission is a malfunctioning torque converter, which can cause shifting problems in automatic transmissions. The torque converter in an automatic transmission serves the same purpose as the clutch in a manual transmission.
Can transmission fluid get low without a leak?
Can you lose transmission fluid without a leak? – Quora. No. There is no combustion, so it can’t just burn up.
