THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH THE 41TE OR 42LE TRANSAXLE.
1992 AC. & AY VEHICLES BUILT AFTER FEB. 15, 1992 (MDH 02-15-XX). **1995 FJ VEHICLES** AND ALL OTHER 1993-1995 SUBJECT
VEHICLES BUILT BEFORE OCT. 24, 1994 (MDH 10-24-XX) ARE VEHICLES EQUIPPED WITH AN ELECTRONICALLY MODULATED
CONVERTOR CLUTCH (EMCC).
Vehicles that operate at speeds where EMCC usage is engaged (vehicle speeds between 34 - 41 MPH), may experience early deterioration of the
transmission fluid (15,000 - 30,000 miles), exhibit a pronounced shudder during EMCC operation, harsh upshifts/downshifts, and/or harsh torque
converter clutch engagements. Performing REPAIR PROCEDURE # 2, which includes updates to the Transmission Control Module (TCM) calibration
and eliminates EMCC, will resolve these symptom/conditions. However, if an overheat condition is identified by the PCM or TCM, EMCC operation
will be temporarily enabled.
**ALL 1995 FJ VEHICLES** AND ALL OTHER 1989-1995 SUBJECT VEHICLES BUILT BEFORE OCT. 24. 1994 (MDH 10-24-XX).
The TCM calibration used in the 1995 model year 41TE and 42LE TCM is being made available for all vehicles dating back to the 1989 model year.
The shift quality improvements and default issues that will be corrected by the new TCM calibration are:
COASTDOWN TIP-IN BUMP: Vehicle is decelerated almost to a stop (less than 8 MPH), then the driver tips back into the throttle to accelerate,
a noticeable bump may be felt.
COASTDOWN SHIFT HARSHNESS: Harsh coastdown shifts on some 4-3, 3-2 and 2-1 downshifts.
1995 LH WITH 42LE TRANSAXLE - SLUGGISHNESS/LACK OF RESPONSE: On some early 1995 LH vehicles built prior to Oct. 24, 1994, a
perceived lack of power or transmission responsiveness may be encountered under normal operating conditions. The transmission may not release
the converter clutch as desired with increased throttle. This occurs in 4th gear from 35 MPH to 50 MPH.
1989-1994 WITH 41TE & 42LE TRANSAXLES: Harsh shifts and/or vehicle shudder during 3-2 or 2-1 kickdowns at speeds less than 25 MPH.
1993 WITH 41TE TRANSAXLE: Harsh 3-4 upshifts may occur, especially at highway speeds, while using the speed control.
1989-1994 WITH 41TE TRANSAXLE - HARSH/DELAYED GARAGE SHIFTS: Delay is less than 2 seconds and the shift is harsh after the
brief delay. NOTE: Delays greater than 2 seconds are caused by transmission hardware malfunction, i.e., valve body, pump, failed lip seals or
