What does flashing D4 mean on Honda Accord?
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.
Should I drive in D4?
You really should only use D4. Unless you’re going down / up really steep hills, then shifting into a lower gear to help you slow down / go up might not be too bad. But for regular driving, shifting an automatic like a manual isn’t a good idea.
Why is my Honda Accord check engine light on?

Is it better to check your oil hot or cold?
1. Park your car on level ground to ensure you get an accurate reading. Turn off the engine and wait 10 to 15 minutes for it to cool down. Manufacturers used to recommend that you check your oil when the engine was cold, to give the oil a chance to settle in the oil pan.
What if the oil level is too high?
When there is too much oil, the rotating crankshaft will cause air to make contact with the oil. Once that happens, the oil becomes very foamy and frothy while circulating through the running engine. This means that the oil is now contaminated and will reduce its effectiveness at lubricating the engine.
Is it OK to slightly overfill oil?
Overfilling your engine oil can cause serious damage to your engine. There is no need for action if the engine oil level is slightly above the max-level. This foamy texture of the oil acts like a bad lubricant, and the oil is not pumped effectively.
What damage can too much oil cause?
Engine damage – Too much lubricant in the system can cause pressure on the crankshaft to increase. This can result in oil entering the crankshaft exhaust pipe, running through into the combustion chamber, blocking the suction hose with oil soot and potentially leading to engine overload.
What happens if oil is overfilled?
When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.
