Jeep 2008 Wrangler - Manual (Page 284)

NOTE: Towing, coasting, or driving the vehicle for any
other reason with the shift lever in NEUTRAL can result
in severe transmission damage. Refer to “Recreational
Towing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
OVERDRIVE
For most city and highway driving. The transmission
contains an electronically-controlled 4th gear Overdrive,
and will automatically shift from DRIVE to OVERDRIVE
if the following conditions are present:
• The shift lever is in DRIVE.
• The O/D OFF switch has not been activated.
• Vehicle speed is above approximately 30 mph (48
km/h).
When frequent transmission shifting occurs while using
Overdrive, such as when operating the vehicle under
heavy load conditions (for example, in hilly terrain,
strong head winds, or trailer towing), turning off over-
drive will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
