TEST ACTION APPLICABILITY
2 The Transmission Fluid temperature must be above 21É C or 70É F prior to checking
fluid level. Adjusting fluid level on a cold transmission will result in an overfilled
transmission.
Check the Transmission Fluid Level per the Service Information.

leak as necessary and adjust the Transmission Fluid Level in
accordance with the Service Information.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.
3 Place the gear selector in park.
Start the engine.
The Transmission must be at operating temperature prior to checking pressure. A
cold Transmission will give higher readings.
Place the Transmission in Reverse.
With the DRBIIIt, observe the Transmission Pressure Switch states.
Are any of the Pressure Switches closed?All
Ye s®Go To 4
No®Go To 6
4 The conditions necessary to set this DTC are not present at this time.
Test drive the vehicle. Allow the Transmission to shift through all gears and ranges.
Did you experience any Delayed Engagement and/ or No Drive condition?All
Ye s®Go To 6
No®Go To 5
5 The conditions necessary to set this DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this
circuit.
Wiggle the wiring while checking for shorts and open circuits.
Were there any problems found?All
Ye s®Repair as necessary.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.
No®Test Complete.
6 Remove and inspect the Transmission Oil Pan and Transmission Oil Filter per the
Service Information.
Does the Transmission Oil Pan contain excessive debris and/or is the Oil Filter
plugged?All
Ye s®Repair the cause of plugged Transmission Oil Filter. Refer to the
Service Information for repair procedures.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.
No®Go To 7
7 With the DRBIIIt, perform a Shift Lever Position test. Follow the instructions on the
DRBIIIt.
Did the Shift Lever Position Test pass?All
Ye s®Go To 8
No®Refer to symptom list and perform test for DTC P0705.

2 Turn the ignition off.
Remove the Transmission Oil Pan and Oil Filter per the Service Information.
Install a new Transmission Oil Filter per Service Information.
Reinstall Transmission Oil Pan, and refill with new Transmission Fluid per the
Service Information.
Note: The Transmission Cooler must be flushed before prodceeding.
Start the engine, check and adjust the Transmission Fluid Level per Service
Information.
Allow the engine to idle for 10 minutes, in Park.
Flush the Transmission Oil Cooler per the Service Information.
Turn the ignition off.
Drain and refill the Transmission Fluid.
Flush the Transmission Oil Cooler again.
Start the engine, check and adjust the Transmission Fluid Level per Service
Information.
With the DRBIIIt, perform a Battery Disconnect.
Note: This must be done to re enable EMCC during an A/C Clutch engage-
ment.
The vehicle may exhibit intermittent shudder during the first few hundred miles.
Note: The oil will gradually penetrate the TCC friction material and the
shudder should disappear.
Erase the DTC and return the vehicle to the customer.
Did the Code reset or does the vehicle still shudder after a few thousand miles?All
Ye s®Replace the Torque Convertor per the Service Information. Note:
After replacing the Torque Convertor, use the DRBIII to perform
the TCC Break In procedure. This will prevent possible shudder
conditions.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.
No®Test Complete.

Symptom:
P1799-CALCULATED OIL TEMP IN USE
When Monitored and Set Condition:
P1799-CALCULATED OIL TEMP IN USE
When Monitored: Whenever the engine is running. The code is set if any of the following
conditions exist for three consecutive key starts: The thermistor voltage is out of range
(below 0.70 volts or greater than 4.94 volts)
Set Condition: If continuos erratic thermistor voltage is sensed. The thermistor temper-
ature stays below 80 degree's Fahrenheit for an extended period time.
POSSIBLE CAUSES
INTERMITTENT WIRING AND CONNECTORS
SPEED SENSOR GROUND CIRCUIT OPEN
TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT OPEN
TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT SHORT TO GROUND
SPEED SENSOR GROUND CIRCUIT SHORT TO VOLTAGE
TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE
TRANSMISSION TEMPERATURE SENSOR INOPERATIVE

TEST ACTION APPLICABILITY
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
