Problem Possible Cause

The AutoShift will not shift untilyou lift off the throttle.

J1939 data link is not working. Check to see if theengine J1939 is turned on. Check the J1939 datalink harness, terminataing resistors. This is an OEMissue.

Place the AutoShift in "D" and button up theMaximum Start Gear. Then try it. If the AutoShiftstill does not shift the dyno has too much drag. TheAutoShift needs to have the rolling inertia from thevehicle. If the dyno has too much drag the rearwheels slow down to fast. This is why the AutoShiftwill not shift.

The only time the AutoShift will shift automaticallyis when the input shaft speed is 300 rpm over ratedspeed of the engine. The AutoShift may have theincorrect engine configuration downloaded into thePush Button Shift Control. This is corrected bydownloading the correct configuration into thePush Button Shift Control, using VEPS orServiceRanger.

The Push Button Shift Control may not have thecorrect software. The easiest way to tell is if theService Lamp is on solid, it is correct. The OEMshift lever or the OEM wiring may be the problem.

The AutoShift has what is called RPM/Load basedshifting. Simply push the upshift button while theshift control is still in "D". For more informationread the Drivers Instruction Guide.

Make sure there is an "N" on the Gear Display. Theproblem is with the Start Enable circuit. Refer toOEM wiring diagrams.

The problem is with the Start Enable circuit. Referto OEM wiring diagrams.

When the key is turned off the AutoShift seems tocalibrate forever. (X-Y Shifter) Several issues couldcause this.

• OEM wiring. Verify the OEM interfaceharnesses.

• Bad Power and Ground. Perform the ElectricalPretest.

• The incorrect transmission ECU. This can beverified using ServiceRanger.

• The X-Y Shifter. The sensors could be bad.

The Autoshift will not shiftacross the Dyno.

The AutoShfit is upshiftingautomatically in "H" or manualmode.

The OEM shift lever does notwork.

The AutoShift will not makeAutomatic shifts even afterlifting off the throttle pedal.

The engine will not start.

The engine will start in anygear.

Problem Possible Cause

Miscellaneous AutoShiftcomplaints

• Always verify the OEM wiring first.

• Check the installation of the AutoShift second.

• Check the AutoShift transmission third.

It is not fault code 5, it is fault code 25, whichmeans no code. The start up procedure for the dashpanel does not allow the 2 to be displayed.

Attempt to clear the code. If fault code 44 comesright back the Transmission ECU may have beenconfigured for a transmission that requires anInertia Brake. This must be confirmed using ServiceRanger. If this is the case the Transmission ECUwill need to be replaced.

Record the fault codes. Clear the fault codes. If thefault codes come right back as active codes.

• Always verify the OEM wiring first.

• Check the installation of the AutoShift second.

• Check the AutoShift transmission third.

After retrieving fault codesthe Gear Display that isintegrated in the dash isdisplaying fault code 5.There is no fault code 5.

There is an active fault code44. Fault code 44 is for theInertia Brake. Thistransmission does not havean Inertia Brake.

There are active fault codespresent.

During power-up, the service light will come on and go off. This is normal operation.But, if the service light comes on and stays on or comes on while driving, it means thetransmission has detected a fault and you’ll want to get to a service facility as soon aspossible.

In the event there is a problem with the transmission, there are three primary tasks thedriver should perform.

• Driving Conditions: Note the driving condition under which the problemoccurred.

• Transmission Conditions: Note the condition of the transmisison under whichthe problem occurred.

• Retrieve Codes / Reset System: Record fault codes and reset the transmissionas described below.

Retrieving Fault Codes

Retrieve transmission fault codes by enabling the transmission system’s self-diagnostic mode.

Note: You can also use a PC-based service tool, such as the ServiceRanger, to retrievetransmission fault codes.

1. Place the shift lever in neutral.

2. Set the parking brake.

3. Turn the ignition key on but do not start the engine. If the engine is alreadyrunning, you may still retrieve codes, however, do not engage the starter ifengine stalls.

4. To Retrieve Active Codes: Start with the key in the on position.Turn the key off and on two times within five seconds endingwith the key in the on position. After five seconds, the servicelamp begins flashing two-digit fault codes. If no codes areactive, the service light will flash code 25 (no codes).

To Retrieve Inactive Codes: Start with the key in the onposition. Turn the key off and on four times within five secondsending with the key in the on position. After five seconds, theservice lamp begins flashing two-digit fault codes. If no codesare active, the service light will flash code 25 (no codes).

Retrieving and Clearing Fault Codes

5. Observe the sequence of flashes on the indicator lamp and record thecodes. A one to two second pause separates each stored code, and thesequence automatically repeats after all codes have been flashed.

Clearing Fault Codes

The following procedure clears all inactive fault codes from the ECU’s memory.(Active fault codes are automatically cleared when the fault has been corrected.)

Note: You can also use a PC-based service tool, such as the ServiceRanger, to cleartransmission fault codes.

1. Place the shift lever in neutral.

2. Set the parking brake.

3. Turn the ignition key on but do not start the engine.

4. Start with the key in the on position. Turn the key off and on six times withinfive seconds, ending with the key in the on position.

Note: If the codes have been successfully cleared, the service lamp will comeon and stay on for five seconds.

5. Turn key off and allow system to power down.
