(5) If at any stage of the cleaning process, the
cooler does not freely pass fluid, the cooler must be
replaced.
OIL COOLER FLOW CHECK
After the new or repaired transmission has been
installed, fill to the proper level with Mopar ATF
Plus (Type 7176) automatic transmission fluid. The
flow should be checked using the following procedure:
(1) Disconnect the From cooler line at the trans-
mission and place a collecting container under the
disconnected line.
CAUTION: With the fluid set at the proper level,
fluid collection should not exceed (1) quart or inter-
nal damage to the transmission may occur.
(2) Run the engine at curb idle speed , with the
shift selector in neutral.
(3) If fluid flow is intermittent or it takes more
than 20 seconds to collect one quart of ATF, replace
the cooler.
(4) If flow is found to be within acceptable limits,
reconnect the cooler line. Then fill transmission to
the proper level, using the approved type of auto-
matic transmission fluid.
TRANSAXLE QUICK LEARN PROCEDURE
The quick learn procedure requires the use of the
DRB scan tool and the DRB scan tool cartridge.
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 Pack Replacement
• Clutch Plate and/or Seal Replacement
• Valve Body Replacement or Recondition
To perform the Quick Learn Procedure, follow the
instructions from the DRB scan tool.
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. A procedure has been developed
called Pinion Factor. It allows the technician to set
the Transmission Control Module initial setting 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 blue CCD Bus
connector. The connector is located under the instru-
ment panel on the drivers side of the vehicle.
(2) Insert the DRB scan tool cartridge into the
DRB scan tool.
(3) The red and green lights on the DRB scan tool
will light up and then begin flashing. Wait until the
lights stop flashing before continuing with this proce-
dure.
(4) Press the number 4 key (Select System) on the
DRB scan tool key pad. Item number 4 will not
appear on the DRB scan tool screen unless you scroll
down. It is not necessary to scroll down to be able to
choose item 4.
(5) Press the number 2 on the DRB scan tool key
pad (Transmission).
(6) Press the number 1 on the DRB scan tool key
pad. Wait for the DRB scan tool to perform the fol-
lowing three tests before continuing.
• Bus Test
• Initialize
• Transmission Control Module Part Number
(7) Press the number 5 on the DRB scan tool key
pad (Adjustments).
(8) Press the number 2 on the DRB scan tool key
pad (Pinion Factor). Then follow the instructions on
the DRB scan tool screen.
