TRANSAXLE QUICK LEARN PROCEDURE
The quick learn procedure requires the use of the
DRB scan tool.
This program allows the electronic transaxle sys-
tem to recalibrate itself. This will provide the best
possible transaxle operation. The quick learn proce-
dure should be performed if any of the following pro-
cedures are performed:
• Transaxle Assembly Replacement
• Transmission Control Module Replacement
• Solenoid/Pressure Switch Assembly Replacement
• Clutch Plate and/or Seal Replacement
• Valve Body Replacement or Recondition
To perform the Quick Learn Procedure, the follow-
ing conditions must be met:
• The brakes must be applied
• The engine speed must be above 500 rpm
• The throttle angle (TPS) must be less than 3
degrees
• The shift lever position must stay until
prompted to shift to overdrive
• The shift lever position must stay in overdrive
after the Shift to Overdrive prompt until the DRB
indicates the procedure is complete
• The calculated oil temperature must be above
60° and below 200°
(1) Plug the DRB scan tool into the data link con-
nector. The connector is located under the instrument
panel.
(2) Go to the Transmission screen.
(3) Go to the Miscellaneous screen.
(4) Select Quick Learn Procedure. Follow the
instructions of the DRB to perform the Quick Learn
Procedure.
PINION FACTOR PROCEDURE
The vehicle speed readings for the speedometer are
taken from the output speed sensor. The TCM must
be calibrated to the different combinations of equip-
ment available. Pinion Factor allows the technician
to set the Transmission Control Module initial set-
ting so that the speedometer readings will be correct.
Failure to perform this procedure will cause a No
Speedometer Operation condition.
This procedure must be performed if the Transmis-
sion Control Module has been replaced.
To properly read or reset the Pinion Factor, it is
necessary to use a DRB scan tool. Perform the follow-
ing steps with the DRB scan tool to read or reset the
Pinion Factor:
(1) Plug the DRB scan tool into the data link con-
nector located under the instrument panel.
(2) Select the Transmission menu.
(3) Select the Miscellaneous menu.
(4) Select Pinion Factor. Then follow the instruc-
tions on the DRB scan tool screen.
