Service Procedure
SERVICE PROCEDURE:1. Attach the GDS and check for Diagnostic Trouble Codes in both the "Engine" and "Automatic Transaxle" menu. If DTCs are found, repair according to the appropriate TSB or shop manual.
2. Check the ATF level when the engine is idling in "P" according to TSB 11-AT-004. Adjust the ATF level as needed using SPH-IV ATF.
* NOTE
Ask an assistant to drive the vehicle as you monitor the GDS.
3. Attach the GDS and select the following:
^ VIN and "A/T" menu
^ "Current Data" (maximum of 8 parameters)
> Current Gear
> Shift Control Solenoid Valve A (UD/C)
> Shift Control Solenoid Valve B (2-6/B)
> Shift Control Solenoid Valve C (36R/C)
> Shift Control Solenoid Valve D (OD/C)
> Shift Control Solenoid Valve E (SS-A)
> Shift Control Solenoid Valve F (SS-B)
4. Shift from P-R, N-D and drive the vehicle through gears 1-2-3-4-5-6 to simulate the complaint condition.
Select "Record" (on top right of screen)
Select "PC Record" (on left of screen)
Save the file.
P-R SHIFT DIAGNOSIS:
Open the GDS program and select:
^ VIN and "A/T"
^ "Flight Record" and "Data Review"
^ Select "Items List" (top right of screen) and select the parameters shown on the graph.
^ Click the "+" or "-" buttons to choose 0.5 sec./Div or less.
^ Move the cursor to the start of the shift and "Left click".
^ Move the cursor to the end of the shift and "Right click".
^ Read the 35R/C solenoid elapsed time at the top right of the screen. If the P-R shift requires more than 2.5 seconds, refer to TSB 11-AT-008-1, "Reset and Relearn Adaptive Values":
> If the shift is less than 0.8 seconds, exchange a PCM from another vehicle and retest.
> If the shift time is more than 2.5 seconds, compare to a similar model and year vehicle. Replace the transmission if the shift time is longer than a comparison vehicle.
N-D SHIFT DIAGNOSIS:
Open the GDS program and select:
^ VIN and "A/T"

^ Move the cursor to the start of the shift and "Left click".
^ Move the cursor to the end of the shift and "Right click".
^ Read the UD/B solenoid elapsed time at the top right of the screen. If the P-R shift requires more than 2.5 seconds, refer to TSB 11-AT-008-1, "Reset and Relearn Adaptive Values":
> If the shift is less than 0.8 seconds, exchange a PCM from another vehicle and retest.
> If the shift time is more than 2.5 seconds, compare to a similar model and year vehicle. Replace the transmission if the shift time is longer than a comparison vehicle.
