TRAILERING EQUIPMENT
SAE Class II hitch with 2 inch (51 mm) square receiver. Trailer may weigh up to 4,000 pounds (1,844 kg) with
proper hitch selection. See the Owners Manual for additional information.
TRANSMISSION
Enhanced calibration 6-speed automatic with overdrive and tow/haul mode. Electronically-controlled
transmission provides protection against over-revving the engine in low gear and a mechanical low gear
blockout is not required; if a driver manually selects low gear and fails to manually upshift to high gear, the
powertrain control module automatically protects the drivetrain. The transmission is calibrated to maintain
lower gears when driving aggressively. This enhances vehicle control while driving through corners and when
throttling up to exit a corner, keeping the transmission in one gear instead of upshifting and downshifting
avoids "hunting" for a gear state
TRANSFER CASE
Autotrac, 2-speed electronic with rotary control, includes neutral position for dinghy towing (2HI, 4AUTO, 4HI,
4LO, and Neutral setting)
