On my 07 there was a switch to turn the OD off, I don't see a switch on the 15, is there any way to turn it off? Thanks.

 

Downshift to 4th with the auto stick.

 

JK's that have the auto stick feature, that has to be used to disable O/D as mentioned above.

 

Thanks for the replies, so If I use the auto stick and downshift to 4 and come to a stop, If I forget to shift down will I be trying to start in 4th? Or does it automatically shift down for you?

 

From the manual:

"When the shift lever is in the DRIVE position, the transmission will operate automatically, shifting between the five available gears. To engage AutoStick®, simply tap the shift lever to the right or left (+/-) while in the DRIVE position. Tapping (-) to enter AutoStick® mode will downshift the transmission to the next lower gear, while using (+) to enter AutoStick® mode will retain the current gear. When AutoStick® is active, the current transmission gear is displayed in the instrument cluster. In AutoStick® mode, the transmission will shift up or down when (+/-) is manually selected by the driver, unless an engine lugging or overspeed condition would result. It will remain in the selected gear until another upshift or downshift is chosen, except as described below.

• The transmission will automatically upshift when necessaryto prevent engine over-speed.
• Heavily pressing the accelerator pedal will generate an automatic downshift (for improved acceleration) when reasonable.
• The transmission will automatically downshift as the vehicle slows (to prevent engine lugging) and will display the current gear.
• The transmission will automatically downshift to first gear when coming to a stop. After a stop, the driver should manually upshift (+) the transmission as the vehicle is accelerated.
• You can start out, from a stop, in first or second gear. Tapping (+) (at a stop) will allow starting in second gear. Starting out in second gear is helpful in snowy or icy conditions.
• The system will ignore attempts to upshift at too low of a vehicle speed.
• Avoid using speed control when AutoStick® is engaged.
• Transmission shifting will be more noticeable when AutoStick® is engaged."

 

Thanks!
