PROCEDURE
1.
Test drive the vehicle to confirm that shift flare occurs at 2-3 shift.
2.
Check the ATF level and color. Correct as necessary. Inspect the A/T drain plug for metal debris.
3.
Start the engine and warm the ATF to 140-212 degrees F (60-100 degrees C). With constant throttle opening at TPS reading 1.7V - 1.8 V, confirm
that the 2-3 upshift occurs between 35 and 40 mph (between 56 and 64 km/h). Continue this driving pattern until the 2-3 shift has occurred five
times.
a.
If the shift flare is not eliminated after the 2-3 shift has occurred five times, continue with Step 4.
4.
Check for DTCs.
a
If any DTC is set, diagnose the DTC as described in the appropriate service manual.
b.
If no DTCs are set, perform the pressure tests for the OD clutch and 2nd brake as described in Group 23 of the appropriate service manual.
Record the pressures on the repair order. Then continue with Step 5.
5.
Open the rear cover. In the seal ring area, inspect the drum, seal rings, and rear cover for grooves, excessive damage, and poor clearance.
