How To Put Hummer In Neutral [Inc. H2 & H3]

Putting a Hummer's transmission into neutral gear is pretty straightforward in most modern cars - step on the brakes (A/T) or clutch (M/T), then slot in the lever to neutral. However, what do you do when your Hummer has a dead battery or is in a torque lock? How do you put Hummer's transfer case into neutral? Here's what our research has uncovered.

If your Hummer's 12-volt battery dies, or if you accidentally put the vehicle's A/T shifter into torque lock, then you need to press the torque lock release button under the shift boot.

If you need to flat tow your Hummer, then you will need to shift the transmission to neutral first. Next, set the transfer case to 4H.

Finally, press the 4H and 4L Lock buttons simultaneously for 10 seconds until the "N" indicator stays steadily lit. At this point, both your transmission and your transfer case are in neutral position.

Would you like to know more about the detailed steps in putting the Hummer's transmission as well as transfer case into neutral? Do read on. We'll give you tips on how to use these modes properly, particularly when the shifter is torque-locked or when you need to flat tow the Hummer.

According to Hummer's owners' manuals, vehicle owners must use the following steps to put the transfer case in neutral safely. Haphazardly shifting the transfer case to neutral can cause major damage to transfer case components, the transmission, and even to lives and property.

  1. Set the parking brake properly.
  2. Start the Hummer's engine.
  3. Shift the Hummer's transmission to neutral.
  4. Set the transfer case to Four Wheel High by pressing and releasing the 4H button.
  5. Press both the 4H (extreme left) and Four Wheel Low Lock (4L Lock, extreme right) buttons simultaneously for 10 seconds.
  6. If the buttons are pressed and held properly, the transfer case control's "N" indicator light will blink before remaining steadily lit. The transfer case should now be neutral.
  7. Put the transmission in gear to test if the transfer case is indeed in neutral.
    • For A/T - Press on the brake pedal while shifting the transmission lever to reverse and to drive. If there are no problems, then you should not feel any backward or forward movement tendencies from the vehicle.
    • For M/T - press on the clutch and brake pedals and shift the transmission to first gear. Release the clutch and brake pedals gently to check for any vehicle movement. Again, the vehicle should be straining to move forward or backward at all.
  8. If step 7 is successful, then you can turn the engine off and shift the transmission lever to park  (A/T) or first gear (M/T).

To resume normal driving operation, you need to put your Hummer's transfer case out of neutral and back into one of its full-time 4WD modes. Here are the steps.

  1. Set the parking brake and step on the brake pedal.
  2. Shift the Hummer's transmission to neutral.
  3. Turn the ignition to the "on" position, without starting the engine.
  4. Press and release the button for your desired transfer case position.  Normally, you would want to select 4H if the Hummer is on level ground.
  5. Start the Hummer's engine.
  6. Shift the transmission to reverse or drive and gently release the brakes to check if the Hummer is back in normal driving operation.

All Hummers come with a full-time 4WD system, meaning all four wheels have power all the time. Here are the Hummers' 4WD transfer case operating modes.
  • High (4H) - This mode is optimal for smooth or paved driving surfaces, but it can also be used in mild off-road situations.
  • High Lock (4H Lock) - The High Lock mode works best for paved surfaces with low traction, such as muddy, snowy, icy, or sandy roads. Keep in mind, however, not to use 4H Lock as a substitute for the 4H mode to prevent excessive tire wear and drivetrain damage.
  • Low (4L Lock) - The Low Lock mode is built for low-speed, low-traction surfaces. Some appropriate driving situations include climbing a boulder, moving through deep snow, fording deep water or mud, or even driving up a steep but low-traction slope.
  • Rear Axle Lock - For H2 and H3 only - adds more traction to escape certain off-road situations (e.g. the vehicle is stuck in a muddy rut). Before locking the rear axle, the transfer case must be in 4L Lock.
  • Front Axle Lock - For H3 only - gives the Hummer H3 even more off-road traction than if only the rear axles were locked. You may lock the front axle only if:
    • The transfer case is already in 4L Lock mode
    • The rear axle is already locked
  • Neutral (N) - disconnects the transfer case; this mode is most useful for flat-towing.

Wrapping Up

To shift a Hummer's transmission to neutral, simply step on the brake pedal (for A/T) or clutch pedal (for M/T) then move the shift lever accordingly.

For A/T models that got stuck in the "Park" gear, you can press the torque lock release button under the shift boot before shifting to neutral.

Putting a Hummer's transfer case to neutral, on the other hand, requires you to press and hold both 4H and 4L Lock buttons simultaneously for 10 seconds.
