VERIFICATION TESTS ÐContinued

> Quick Learn should generally not be used as a
repair procedure unless directed by a repair or
diagnostic procedure. If the transmission system
is exhibiting a problem that you think is caused
by an invalid CVI, you should try to relearn the
value by performing the appropriate driving ma-
neuver. In most cases, if a quick learn makes a
vehicle shift better, the vehicle will return with
the same problem.
> Before performing Quick Learn, it is imperative
that the vehicle be shifted into OD with the
engine running and the oil level set to the correct
level. This step will purge air from the clutch
circuits to prevent erroneous clutch volume val-
ues which could cause poor initial shift quality.
> If an unused TCM is installed on a vehicle with a
HOT engine, Quick Learn will cause the TCM to
report a cold calculated oil temperature. This
requires monitoring the calculated oil tempera-
ture using the DRBIIIt. If the temperature is
below 15C (60É F), the transmission must be run
at idle or driven in gear until it goes above 15C
(60ÉF). If the temperature is above 93C (200ÉF),
the transmission must cool to below 93C (200ÉF).
> First gear is engaged in overdrive after Quick
Learn is completed. Place the vehicle in park
after performing Quick Learn.
The Quick Learn function should be performed:
± Upon installation of a new service TCM
± After replacement or rebuild of internal trans-
mission components or the torque converter
± If one or more of the clutch volumes indexes
(CVI's) contain skewed readings because of
abnormal conditions.
To perform the Quick Learn procedure, the fol-
lowing conditions must be met.
± It is imperative that the vehicle be shifted into
OD with the engine running and the oil level
set to the correct level. This step will purge the
air in the clutch circuits to prevent erroneous
clutch volume values, which could cause poor
initial shift quality.
± The brakes must be applied.
± The engine must be idling.
± The throttle angle (TP sensor) must be less
than 3 degrees.
± The shift lever position must stay in neutral
until prompted to shift into OD.
± The shift lever must stay in OD after the9Shift
to Overdrive9prompt until the DRBIIItindi-
cates the procedure is complete.
± The oil temperature must be between 15C
(60ÉF) and 93C (200ÉF).NOTE:The above conditions must be maintained
during the procedure to keep the procedure from
being aborted.
The Quick Learn procedure is performed with the
DRBIIItby selecting9Transmission9system then
9Miscellaneous9functions, then9Quick Learn9. Follow
the procedure instructions displayed on the DRBIIIt.
3.3.9 CLUTCH VOLUMES
The L-R clutch volume is updated when doing a
2-1 or 3-1 coast down shift. The transmission tem-
perature must be between 21-49C (70-120É F). The
clutch volume should be between 35 and 83.
The 2-4 clutch volume is updated when doing a
1-2 shift. The transmission temperature must be
above 43C (110ÉF). The clutch volume should be
between 20 and 77.
The OD clutch volume is updated when doing a
2-3 shift. The transmission temperature must be
above 43C (110ÉF). The clutch volume should be
between 40 and 150.
The UD clutch volume is updated when doing a
4-3 or 4-2 shift. The transmission temperature must
be above 43C (110ÉF). The clutch volume should be
between 24 and 70.
3.3.10 ELECTRONIC PINION FACTOR
The transmission output speed signal supplies
distance pulses to the powertrain control module
(PCM), which are used to calculate speed and
mileage. A pinion factor is stored in the transmis-
sion control module (TCM) in order to provide the
appropriate distance pulses for the vehicle. The
pinion factor is programmed into the TCM at the
assembly plant.
Using the following steps, the pinion factor can be
checked and/or reset using the DRBIIIt:
1. Select Transmission system, then Miscellaneous
functions, then Pinion Factor. The DRBIIItwill
display the current tire size.
2. If the tire size is incorrect, depress the Enter key
and then select the correct size.
3. Depress the Page Back key to exit the reset
procedure.
Notes About Electronic Pinion Factor Features
The nature of the electronic pinion factor requires that
certain features must be taken into consideration.
> If no pinion factor is stored in an installed TCM,
the vehicle speedometer will not operate, engine
speed will be limited to 2300 RPM, and catalyst
damage may occur.
> Selecting a wrong tire size will cause the speed-
ometer to be inaccurate and will also cause any
speed related features to operate improperly.
Note: After replacing the TCM, you must
reprogram pinion factor

1NOTE: Low fluid level can be the cause of many Transmission problems. If
the fluid level is low locate and repair the leak then check and adjust the
fluid level per the Service Information.
NOTE: Always perform diagnostics with a fully charged battery to avoid
false symptoms.
With the DRBIIIt, read the engine DTC's. Check and repair all engine DTC's prior
to performing Transmission Symptom Diagnostics.
With the DRBIIIt, read Transmission DTC's. Record all DTC's and 1 Trip Failures.
NOTE: Diagnose 1 Trip Failures as a fully matured DTC.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Repair as necessary.
Perform the Shift Lever Position Test. If the test does not pass, refer to Symptom test
for P0705 Check Shifter Signal.
For Gear Ratio DTC's, check and record all CVI's.
Most DTC's set on start up but some must be set by driving the vehicle such that all
diagnostic monitors have run.
NOTE: Verify flash level of Transmission Control Module. Some problems
are corrected by software upgrades to the Transmission Control Module.
NOTE: Check for applicable TSB's related to the symptom.
Perform this procedure prior to Symptom diagnosis.All
