Drive gear too much play in shifting gears and I don,t have owners manual

What type of vehicle? Most manufactures have an override button that will enable the vehicle to get into gear if there is a failure in the electronics. Have a look in your owners manual to see if your vehicle is equipped with an override and how to engage it.

Owners of a Toyota 4Runner might panic when the gearshift begins to have problems. Knowing a couple of the things that often go wrong in a 4Runner can help a driver diagnose or even repair the gearshift himself. Following are some of the more common shifting problems with 4Runners, and a bit of information on what to do next.
Shift Solenoids

• One of the leading causes of gearshift issues in automatic 4Runners is a bad "shift solenoid." In automatics, shifts are controlled by shift solenoids, electrical coils that change gears automatically. These solenoids can go bad over time and cause stuttering between gears, or prevent shifting beyond a certain gear. Shift solenoids can be purchased and replaced on your own. By consulting the owner's manual, you can determine the location on the valve body of your vehicle and check shift solenoids for breakage or rupturing. Replacing these on your own isn't terribly difficult, as long as you are certain the shift solenoid is the problem. Tutorials are available in car repair manuals and sometimes are posted online.
  

Transfer Case

• When a 4Runner begins to have shifting problems, the transmission is often fingered immediately as the culprit. A driver might change the transmission fluid and filter, only to find that the car slips into the same shifting problems. Four-wheel-drive vehicles utilize a transfer case that ensures shifting between two-wheel and four-wheel drive. If a vehicle has a difficult time shifting into two-wheel or four-wheel-drive high, but works on four-wheel-drive low, examine the transfer case. Common problems include linkage breaks and worn gears.
  

Shift Lever Seat

• Sometimes, the gearshift on a manual simply doesn't feel right. The vehicle might come out of gear too easily or have a problem upshifting or downshifting. The shift lever seat is the well in which the stick shift rests. After years of use, pieces might break off, bend or rust, causing problems with gearshifts that don't stay where they should or have a hard time getting there. Fixing your shift lever seat is quite simple and takes about 45 minutes. Once the boot cover and plate cover have been removed, you need only examine, remove debris, grease up, and reassemble. Such a fix can cost serious time and money at a mechanic, so try it on your own if you have the time and the proper equipment. The proper equipment includes a screwdriver and/or wrench to remove the boot cover and plate, a soft cloth to remove dirt, and grease for lubricating the shift lever.
  

Good Luck.

I don't think Hang On has a DIP switch for gear shifting or speed, it sounds like you may need to calibrate or replace some of the controls. Here is a link to the owner's manual.

Pretty much all the time!

D3, D4, and D5 are all just *DRIVE* like on any automatic transmission, EXCEPT
that the number next to the D is the "highest gear the automatic transmission will go into".
The Acura just gives you a choice, in case you don't want to go into a higher gear (like if it's slippery traction or a steep hill, etc.)

1 means: Manual gear. FIRST GEAR ONLY.
2 means: Manual gear. SECOND GEAR ONLY.
D3 means: Use automatic transmission, but engine will never shift above 3rd gear.
D4 means: Use automatic transmission, but engine will never shift above 4th gear.
D5 means: Use automatic transmission, but engine will never shift above 5th gear.

On any suv with 2 and 4 wheel drive options 4 low generally means that the transmission is in 4 wheel drive low gearing option so that the most possible torque is transferred to the wheels by way of what would be called a granny gear. What you will need to do is check your 4 wheel drive settings to see if the transmission has been put into this option which is either on a separate shift lever or a push button either on the shift handle or on the dash. Your owners manual should also direct you to where the selector is at.

Try changing your gear oil. Make sure you look in the owners manual to get the correct kind of lubricant for your car.
