I have an '05 Quest with automatic transmission. The shift stops are P-R-N-D-3
While in D (Drive) mode I used to be able to hit the overdrive button which put the gear in 4. Likewise while driving in 3 (3rd gear) I used to be able to hit the button and downshift into 2 (2nd). Neither of those are working anymore. What could it be?
Most likely the turning on and off might have trigered or burned out your relay switch located in the front of your engine. The overdrive button on your nissan was only ment to be used sporadically and not as a stick vehicle ( According to your expression ). You can purchase this relay in your nearest nissan dealer. Good luck.

What trans? AOD? This is 1992 F Series, all I have.
Shift Controls, Automatic Transmission
The transmission shift control linkage or cable transfers the transmission operating mode from the selector lever to the transmission. The indicated transmission position on the steering column is transferred to a shift lever on the bottom of the steering column. On vehicles equipped with cable-operated shift systems, the indicated position of the transmission selector lever is transferred to the transmission through the shift cane, then to the cable, and down to the transmission manual shift lever at the transmission. On vehicles equipped with shift rod assemblies, the rod transfers the indicated transmission selector level position through a bell crank assembly to a control rod. The control rod transfers the indicated position to the transmission assembly.
Automatic Transmission Manual Linkage Adjustments
With the engine stopped and the parking brake applied, place the transmission selector lever at the steering column in the D (DRIVE position) for C6 applications and in the (D) (OVERDRIVE position) for AOD and E4OD applications, and hold against the D or (D) stop by applying a three-pound force to the selector lever knob.
Loosen the shift rod adjusting nut at point A. Refer to the following illustrations.
Shift the manual lever at the transmission into the (D) (overdrive) position for E4OD, by moving the lever all the way rearward, then forward two detents.
With the selector lever and transmission manual lever in the(D) position, tighten the nut at point A to 17-24 Nm (12-18 ft-lb) torque. Use care to prevent motion between the stud and rod.
Remove the three-pound force from the steering column selector lever knob.
Operate the shift lever in all positions to make certain that the manual lever at the transmission is in full detent in all gear ranges. Re-adjust the linkage if required.
On F-Super Duty Chassis Cab and Motorhome and Commercial Chassis recheck for correct operation of the automatic transmission selector indicator (PRN(D)21). Refer to Section 11-04A, Steering Column, Shift Rod Within Tube.
CAUTION: Under no circumstances will it be permissible to adjust linkage in any position other than the(D) position for E4OD applications.
From inside the vehicle, place the column shift select lever in the DRIVE position (C6) of the OVERDRIVE (AOD and E4OD). Hang a three-pound weight on the selector lever.
Raise vehicle on a hoist.
Remove the shift cable from the transmission lever ball stud.
Pull down the lock tab on the shift cable body.
Position the transmission shift lever in the DRIVE position (C6) or the OVERDRIVE position (AOD and E4OD). This is three detents from the front-most lever position with the first position counting as one.
Connect the cable end fitting to the transmission lever ball stud.
Push up on the lock tab to lock the cable in the correctly adjusted position.
Lower vehicle down from hoist and remove the three-pound weight from the column shift select lever.
After making the adjustment, check for park engagement. Check the transmission control lever in all detent positions with the engine running to make sure correct detent/transmission actions. Readjust if necessary.
Usually this is a button on the end of a shifter or on the dash around the gauge cluster but in this instance there is no button and your car is most likely driving in safe mode and you will have to take it to have it checked for engine/transmission codes to find out what the problem is.
Over Drive..... Generally speaking, overdrive (OD) 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. When it is switched on, an automatic transmission can shift into overdrive mode after a certain speed is reached (usually 70+ km/h [43+ mph] depending on the load). When it is off, the automatic transmission shifting is limited to the lower gears. For an automatic transmission, it is almost always best to select overdrive and allow the transmission to control engagement of the overdrive. (It may be necessary to switch it off if the vehicle is being operated in a mountainous area or when towing a trailer.) With a manual transmission, overdrive should usually be selected when the average speed is above 70 km/h (approx. 43 mph).
Sounds like the shift kit is warn out in the transmission. The overdrive line may not be able to provide enough hydrolic pressure to engage the gears to move the truck. When you switch to regualr drive, that line is able to build the hydrolic pressure to engage the gears. At a certian speed (for the transmission, certian hydrolic pressure) there is enough pressure to engage the gears in overdrive, but go below that, and you have to start in drive again. If this is the case, there is no easy fix for that and I recomend taking it to a transmission shop to have your shift kit examined. Opening up an automatic transmission requires specalized tools, clean shop enviroment, and knowlage more then the average back yard machanic has.
Honda transmissions,as well as most other overdrive transmissions,should be driven at all times in drive 4,or the overdrive position,with the exception of severe driving conditions,such as towing a load,extremely hilly terrain,or long uphill grades,the trans should be taken out of overdrive,and placed in the drive 3 position.This is to prevent the perpetual shifting back and forth of the trans from 3rd into 4th,back to 3rd,back to 4th,back to 3rd,that would eventually damage both the 3rd and 4th gear clutch discs and components.
