23. Reconnect all connectors.
24. Update the PCM if it does not have the latest
software (see page 11-227), or substitute a known-
good PCM (see page 11-7).
25. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
26. Test-drive the vehicle in 3rd gear with the shift lever in D for at least 2 seconds, then drive in 4th
gear for at least 2 seconds.
27. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals between the 3rd clutch transmission fluid
pressure switch and the PCM. If the PCM was
updated, substitute a known-good PCM (see page
11-7), then go to step 25. If the PCM was substituted,
go to step 1.
Go to step 28. 28. Monitor the OBD STATUS for P0848 in the DTCs
MENU with the HDS.
If the PCM was updated, troubleshooting is
complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated in step 27,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals between the 3rd
clutch transmission fluid pressure switch and the
PCM. If the PCM was updated, substitute a known-
good PCM (see page 11-7), then go to step 25. If the
PCM was substituted, go to step 1. If the HDS
indicates NOT COMPLETED, go to step 25.
Is DTC P0848 indicated? Does the HDS ind icate PASSED?

1. Apply the parking brake, and block both rear
wheels.
2. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
3. Shift to D while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The
engine should not stall.
4. Repeat step 3 in all shift lever positions.
5. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
6. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).7. Prepare the HDS to take a HIGH SPEED SNAPSHOT
(refer to the HDS user guide for more details if
needed):
 Select High Speed icon.
 Select these parameters: – Vehicle Speed
– Output Shaft (Countershaft) Speed (rpm)
– Input Shaft (Mainshaft) Speed (rpm)
– Engine Speed
– APP Sensor A (V)
– ATF Temp Sensor (V)
– Battery Voltage
– Shift Control
– Brake Switch
 Set the Trigger Type to Parameter.
 Adjust the Parameter setting to APP Sensor A above 1.2 V.
 Set the recording time to 60 seconds.
 Set the Trigger point to 30 seconds.
8. Find a suitable level road. When you are ready to do the test, press OK on the HDS.
9. Monitor the HDS and accelerate quickly until the APP Sensor A reads 1.3 V. Maintain a steady
throttle until the transmission shifts to 5th gear,
then slow the vehicle and come to a stop.
10. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary
and repeat step 9.
11. Adjust the Parameter setting to 2.4 V. Retest-drive the vehicle. While monitoring the HDS, accelerate
quickly until the APP Sensor A reads 2.5 V.
Maintain a steady throttle until the transmission
shifts to 5th gear (or reasonable speed), then slow
the vehicle and come to a stop.
12. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary
and repeat step 11.
13. Accelerate quickly until the accelerator pedal is to the floor. Maintain a steady pedal until the
transmission shifts to 3rd gear, then slow to a stop,
and save the snapshot.

A
1. Make sure the transmission fluid is filled to the
proper level (see page 14-231).
2. Apply the parking brake, and block all four wheels.
3. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
4. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).
5. Make sure the A/C switch is OFF.
6. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
7. Shift to D while pressing the brake pedal firmly, then fully press the accelerator pedal for
6 to 8 seconds, and note the engine speed. Do not
move the shift lever or remove your foot off the
brake pedal while raising the engine speed.
8. Allow 2 minutes for cooling, then repeat the test in SandR.
NOTE: Do not test the stall speed for more than 10 seconds at a time.
 The stall speed tests should be used for diagnostic purposes only.
 Stall speed test results should be the same with the shift lever in D, S, and R.
 Do not test the stall speed with the A/T oil pressure gauges installed. 9. If the stall speeds are out of the service limit, the
problems and probable causes are listed in the
table.
