ALL
SYMPTOM
The transmission has intermittent harsh or jerky upshifts with steady acceleration, or the MIL comes on with DTC
P0716.
POSSIBLE CAUSES
Abnormal TCM adaptation values or a miscalculation in the TCM software causes the MIL to come on with DTC P0716.
NOTE
For the hard upshift concern, make sure the vehicle has at least 500 miles on the odometer because it takes that long
for the TCM to adapt to the customer's driving pattern.
CORRECTIVE ACTION
Update the TCM.
NOTES
•
This software update repairs two different symptoms: Intermittent harsh or jerky shifts with steady acceleration and
MIL coming on with DTC P0716. Any other conditions continue with normal system troubleshooting.
•
Have the service manager or service advisor explain to the customer that after the TCM update, it will take about
500 miles for the TCM to adapt to the customer's drive pattern.

REPAIR PROCEDURE
NOTES
•
Make sure the 12-volt battery is fully charged before starting an update.
•
Connect a fully charged jumper battery to the vehicle, and leave it connected during the entire procedure to maintain
steady voltage.
•
Do not use the GR8 because the vehicle requires a steady electrical current.
•
Control module failure caused by the improper completion of a software update (early key cycle, low battery voltage,
disconnected DLC cable, etc.) is not covered by warranty.
•
If an error occurs during the update or the i-HDS freezes, do not disconnect the battery or turn the ignition to
OFF. Reboot the i-HDS, and start over.
•
To prevent control unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power
windows, door locks, etc.) during the update.
•
Warranty reimbursement for technician labor is not allowed for routine checking/installation of any available
software update.
1. Verify the customer concerns for the intermittent harsh or jerky upshift with steady acceleration or the MIL or OBS is
on with DTC P0716.
NOTE
This service bulletin does not apply to vehicles with a hard downshift or hard upshift using the paddle shifters or
vehicles with under 500 miles on the odometer, Follow normal system troubleshooting.

500 miles for the TCM to adapt to the customer's drive pattern.
