When shifting into or out of 4L some gear noise may be heard. This noise is normal and is not detrimental to the vehicle or occupants.
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift the transmission into NEUTRAL. While the vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case lever firmly to the desired position. Do not pause in transfer case Neutral.
Pausing in transfer case N (Neutral) in vehicles equipped with an automatic transmission may require shutting the engine off to avoid gear clash while completing the shift. If difficulty occurs, shift the transmission into N (Neutral), hold your foot on the brake, and turn the engine off. Complete the range shift to the desired position.
Shifting into or out of 4L is possible with the vehicle completely stopped, however difficulty may occur due to the mating teeth not being properly aligned. Several attempts may be required for teeth alignment and shift completion to occur. The preferred method is with the vehicle rolling 2 to 3 mph (3 to 5 km/h). Avoid attempting to engage or disengage 4L with the vehicle moving faster than 2 to 3 mph (3 to 5 km/h).
Do not attempt to shift into or out of 4L while the transmission is in gear.
