10 Most Common Transmission Problems

Ever notice that while driving that the car hesitates or refuses to go into gear? ... but after shifting into gear the engine's RPMs will surge, but the car won't move as fast as the ..... It's slow to shift gears and accelerate in Reverse, D4,D3,2 and 1.

D4 is where you want to spend most of your time as this is the overdrive gear. About the only time you will need to run in D3 is if you are climbing steep grades or, if equipped with a tow kit, pulling a load.

In your Lincoln LS, you will have 3 transmission options to choose from. The first is the SelectShift, which operates similar to a manual transmission but without the clutch. The other 2 are the D4 and D5 options that you are referring to. The number after the D is really a reference to how many gears it will shift through. D4 = 4 gears, D5 = 5 gears. All that being said, it really should operate closer to a 4 gear transmission with an overdrive gear when the car is in D5. Think of it like the "drive" and "overdrive" in other cars. I have heard that to maximize fuel economy, use D5 for highway driving and D4 for city driving.

Here's the manual.

If the D4 light is flashing, you have a transmission control failure and you need to get your transmission and transmission control system checked out.

use d4. d4 is for normal driving. d3 is to down shift the transmission in case you wanna pass. use d3 only if you want to down shift because if you leave your car in d3 on the highway, it doesnt allow the 4th gear to engage, causing your engine to run at higher revs, not only wasting more gas but also making your engines life last less. hope this helps. if you need more help, let me know. goodluck

drivre in D4

you need to check the codes for the trans first.
have to contact the honda dealer for a radio code.
needs a clock light bulb.

D4 - this gear means that all four automatic gears will be able to work (1,2,3,4)
D3 - Three gears will be able to work (1,2,3)
D2 - Two gears (1,2) - L2 means the same thing
D1 - One (low) gear (1)

For your car, drive it in d4. this means that all forward gears will work, including overdrive (4th gear). It will be fine to leave your car in this gear.
