Home x-old ACPN Tech Tip: Mitsubishi 2-3 Shift Flare, Slipping

Print Print Email Email

Some customers may complain of shift flare when shifting from second gear to third gear. This bulletin contains procedures for diagnosing and repairing this condition. New, improved parts are listed in the Parts Information section of this bulletin.

Affected vehicles: 1997-2002 Mirage, 1999-2005 Galant, 2000-’05 Eclipse, 2001-’04 Diamante, 2001-’05 Eclipse Spyder, 2002-’05 Lancer, 2003-’05 Outlander, 2004 Lancer Sportback Wagon and 2004-’05 Endeavor

Procedure:
1. Test-drive the vehicle to confirm that shift flare occurs at the 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° F (60-100° C). With constant throttle opening at TPS reading 1.7-1.8V, 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 second 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. See Fig. 1.

Fig. 1

Note: Perform this inspection/repair with the transmission assembly in the ­vehicle.

a. If any grooves, damage or clearance problems are found, replace the following parts with the new, improved parts listed in the Parts Information chart at right.

– Reverse/OD Clutch Assembly (with drum)
– Reverse Retainer
– Seal Rings
– Rear Cover
– Input Shaft Rear Bearing

b. If no grooves, damage or clearance problems are found, follow the diagnosis procedure in Group 23 of the appropriate service manual.
