With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Tem-
perature is HOT, above 43° C or 110° F.
Check the transmission fluid and adjust if necessary. Refer to the ServiceInformation for the Fluid Fill proce-
dure.
Road test the vehicle. With the scan tool, monitor the engine RPM. Make 15 to20 1-2, 2-3, 3-4 upshifts.
Perform these shifts from a standing start to 45 mph with a constant throttleopeningof20to25degrees.
With speeds below 25 MPH, make 5 to 8 wide open throttle kickdowns to 1st gear. Allow at least 5 seconds
each in 2nd and 3rd gear between each kickdown.
For a specific DTC, drive the vehicle to the Symptom’s When Monitored/WhenSet conditions to verify the DTC
is repaired.
If equipped with AutoStick, upshift and downshift several times using the AutoStickfeature during the road
test.

2. Move selector lever to the DRIVE position.
3. Allow vehicle front wheels to turn and increase throttle opening to achieve an indicated vehicle speed of 30 mph.
Vehicleshouldbeinfourthgear.
4. The 2/4 clutch pressure should read 75 to 95 psi.
TEST FIVE-SELECTOR IN DRIVE (OD ON - Fourth Gear, CC on)
NOTE: These tests check the torque converter clutch hydraulic circuit.
1. Attach gauge to the torque converter clutch off pressure tap.
2. Move selector lever to the DRIVE position.
3. Allow vehicle wheels to turn and increase throttle opening to achieve anindicated vehicle speed of 50 mph.
Vehicle should be in 4th gear, CC on.

5. Now attach the gauge to the torque converter clutch on pressure tap.
6. Move selector to the OD position.
7. Allow vehicle wheels to turn and increase throttle opening to achieve anindicated vehicle speed of 50 mph.
8. Verify the torque converter clutch is applied mode using the RPM displayof the scan tool.
9. Torque converter clutch on pressure should be 60-90 psi.
TEST SIX-SELECTOR IN REVERSE
NOTE: This test checks the reverse clutch hydraulic circuit.
1. Attach gauge to the reverse and low/reverse clutch tap.
2. Move selector lever to the REVERSE position.
3. Read reverse clutch pressure with output stationary (foot on brake) andthrottle opened to achieve 1500 rpm.
4. Reverse and low/reverse clutch pressure should read 165 to 235 psi.
TEST RESULT INDICATIONS
1. If proper line pressure is found in any one test, the pump and pressure regulator are working properly.
2. Low pressure in all positions indicates a defective pump, a clogged filter, or a stuck pressure regulator valve.
3. Clutch circuit leaks are indicated if pressures do not fall within the specified pressure range.
4. If the overdrive clutch pressure is greater than 5 psi in Step 6 of Test Three, a worn reaction shaft seal ring or
a defective solenoid assembly is indicated.
