Reason for Version 2 of this Service Bulletin

The changes to this document have a black line against them in the left margin. Please destroy all copies of SB-07-1316

and replace them with Service Bulletin SB-07-1316V2.
Reason for this Service Bulletin

A seven-speed manual transmission is offered as an option for Vantage. This Service Bulletin introduces the technical

aspects of this transmission.
Manual Transmission with AMShift

The seven-speed manual transmission features a dog-leg configuration. This makes sure that the gears used most

frequently are aligned in a double ‘H’ pattern like a conventional six-speed manual.

The seven-speed manual transmission also includes the AMShift feature. This feature lets the driver change gear without

the need to lift their foot off the accelerator pedal when a gear change is made. This can also simulate the technique of

heel-and-toe downshifts and allow full-throttle upshifts under acceleration.

The transmission is also compatible with the vehicle Stop/Start system.

Workshop Procedure

When the Engine Management System learns and stores the clutch “bite” point, it adapts this point as the clutch

components wear. When a new clutch is installed, or existing components are removed and installed again, the

adaptions must be learned again to give the new position of the clutch components. When you do the clutch learn

procedure, this gives the system an accurate position to calculate when and how much engine torque is transmitted to

the driveline. This is important for the AMShift speed matching function to work correctly.

CAUTION: WHEN ANY WORK RELATED TO THE CLUTCH IS COMPLETED, YOU MUST ALWAYS PERFORM THE

AMDS PROCEDURE “CLUTCH ADAPTATION AMSHIFT”. IF YOU DO NOT, THIS MAY CAUSE DAMAGE TO THE

TRANSMISSION.

As AMShift uses input signals from the clutch system, the clutch adaptation values and learn procedures must be done

when any work related to the clutch is completed. This includes installation of new parts and when the same parts are

installed again, this includes the parts that follow:

•
Clutch removal or related hardware. This includes when you bleed the slave cylinder or master cylinder.
•
Clutch pedal sensor.
•
Pedal box assembly.
•
Driveline (Torque tube, drive shaft, and transmission).
•
When you have replaced the Engine Management System (EMS) module.
•
Sensors or switches for the AMShift system.
Clutch Adaptation Procedure

1.
Do an AMDS Operation Check (refer to Workshop Manual procedure 00.06.AD).

Note: There must be no Diagnostic Trouble Codes (DTCs) stored in the EMS before you proceed to the next

step. If a DTC is found this must be repaired before you continue.
2.
Open the Data Monitor in AMDS2 (refer to user guides).
3.
Set the Data Monitor to read DID 9a0a (Clth_flgLrngRst) in ECM_V8.
4.
Set the ignition to position ‘II’.
5.
Fully push and release the brake pedal at least three times. Push and hold the brake pedal down after the last

push.
6.
Fully push and hold the accelerator pedal down.

Note: The clutch pedal must not be pushed.
7.
Press the AMShift button to complete the procedure.

Note: The red warning triangle and the message ‘AMShift Service Required’ will show in the instrument

cluster when the reset procedure is complete. The DID Clth_flgLrnRst will momentarily go to “1” to show

the reset is complete.

Clutch Learn

CAUTION: MAKE SURE THAT THE CLUTCH ADAPTATION PROCEDURE HAS BEEN COMPLETED BEFORE YOU

DO THE CLUTCH LEARN PROCEDURE.

1.
Do an AMDS Operation Check (Refer to Workshop Manual procedure 00.06.AD).

Note: There must be no DTCs stored in the EMS before you proceed to the next step. If a DTC is found this

must be repaired before you continue.
2.
Set the ignition to position ‘II’.
3.
Start the engine and let the engine idle.
4.
Fully push and slowly release the clutch pedal two times. The pedal must be moved to its maximum and

minimum positions each time.

Note: The clutch pedal does not need to be held down after the second push.
5.
Set the ignition to off.
6.
Make sure the EMS has fully shut down – leave the vehicle locked with the key away from the vehicle for more

than 15 minutes.
7.
After 15 minutes, set the ignition to position ‘II’.
8.
The clutch is now adapted and the message “AMShift Service Required” will be removed from the instrument

cluster. The AMShift feature will be selectable with the AMShift button.
9.
Do an AMDS Operation Check (refer to Workshop Manual procedure 00.06.AD).

Note: There must be no DTCs stored in the EMS before you proceed to the next step. If a DTC is found this

must be repaired before you continue.
10.
Set the ignition to ON and do an AMDS Operation Check (refer to Workshop Manual procedure 00.06.AD).

The clutch learn will be successful if DID $9A$09 / Clth_flgRngAdpnDone = true.
Neutral Sensor Adaptation

Note: This procedure only needs to be done if a new ECM is installed or new software is flashed to the ECM.

1.
Make sure the engine is set to ON.
2.
Make sure the Stop/Start system is set to off.
3.
Test drive the vehicle and do 3 idle phases in neutral for approximately 10 seconds.

Note: The clutch pedal must not be pressed when you do the 3 idle phases.
4.
Drive the vehicle between each idle phase at greater than 10 km/h at varied speeds.
5.
Accelerate constantly for 10 seconds in a gear from the upper gear row (2nd, 4th, 6th) and lower gear row (1st, 3rd,

5th, 7th) for a positive torque adaptation.
6.
Do a 10 second constant deceleration with an upper and lower row gear for an overrun adaptation.

Notes: Brakes should not be used.

IMPORTANT – 1st gear must not be used to do the overrun.
7.
Leave the vehicle stationary in neutral with the engine set to ON and check the DID values with the SEL file

provided.

DID 9A$0C Gbx_stNPosMT==true (pass) under the conditions that follow (all must be true):

•
DID 20$00 nmot_w>600rpm and nmot_w
