Speed Control Performance - AOD, AXOD and MTX5

As noted in the Owner's Guide, it may be preferable to shift the AOD or AXOD to the "D" (overdrive lockout) or the MTX5 to 4th gear in mountainous areas or at high altidude to improve speed control performance.

On steep upgrades the vehicle may not be able to maintain speed while in overdrive, or 5th gear, resulting in a speed drop below the set speed. If the speed drop exceeds approximately 10-13 MPH, the speed control will automatically disengage and must be reset with the SET/ACCEL button. Performance will be improved by shifting to "D" (AOD or AXOD) or to 4th (MTX5).

If speed control performance is poor on moderate grades, the adjustment of the Bowden cable/bead chain should be checked and readjusted if necessary. The automatic transmission shift linkage should also be checked for proper adjustment.
