Stratus V6-2.5L VIN H (1997)
close to the calculated oil temperature at start-up.
The "TRANS TEMP DEG" and "TRANS TEMP STATE" seen on the DRB Ill may be derived from either the thermistor value or
calculated oil temperature depending on fault or no fault conditions. To read the thermistor value for diagnostic purposes, use "TRANS
TEMP VOLTAGE" on the DRB III with the engine running. This will give the actual thermistor value in volts and can be used to decide if
the thermistor circuit is at fault. If the thermistor circuit is out of range, always check to make sure the electrical connections are
corrosion/contamination free when performing diagnostics.
All PRNDL lights on with or without DTC 28 - CHECK SHIFTER SIGNAL. Possibly caused by a TRS circuit fault.
When shifter is moved between the 2/3 or L positions, transaxle stays in original position until driver shifts to OD/D or to N then back to
OD/D. Possibly caused by a TRS circuit fault.
Intermittent limp-in (stuck in second gear) with pressure switch, speed sensor, or gear ratio DTC's. The new software will set the DTC when
the fault is identified, but will not cause a limp-in condition until the fault has occurred several times.
Improves the shift schedule while towing in hilly conditions. The driver may describe this condition as being in the wrong gear or delayed upshifts
after cresting a hill.
Includes capability to set new/improved DTC's (ie. DTC 76 - POWER UP AT SPEED etc.) and make use of the latest diagnostic tests listed in the
41TE/AE diagnostic manual (p/n 81-699-97148) and 42LE diagnostic manual (pin 81-699-97031).
On FJ 2.0L (non turbo) models:
Uses the 97 shift schedules on 96 model vehicles. Enhances mid throttle performance.
On 96/97 3.5L LH models:
Reduces engine surge during full EMCC application by raising its application from 41 mph to 47 mph.
VEHICLES THAT EXHIBIT THIS CONDITION MUST HAVE THE POWERTRAIN CONTROL MODULE FLASHED. **SEE TSB
18-15-98 FOR 96197 3.5L LH LIGHT SURGE BETWEEN 42 AND 50 MPH FOR MORE DETAILS.**
Using the Mopar Diagnostic System (MDS) or the Diagnostic Scan Tool (DRB III) with the appropriate Diagnostic Procedures Manual, verify all
engine/transmission systems are functioning as designed. If unrelated Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and
repair as necessary before proceeding further with this bulletin. If DTC's that relate to the above conditions are present or if the customer describes any
of the conditions listed above, perform the Repair Procedure.
WHENEVER A TRANSMISSION CONTROL MODULE (TCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE
REPLACEMENT CONTROLLER SHOULD BE VERIFIED FOR THE LATEST REVISION LEVEL. USE THE FLASH PROCEDURE TO
UPDATE REPLACED CONTROLLERS AS NECESSARY.

THE MDS AND DRB III(R) ARE REQUIRED TO PERFORM PART OF THIS REPAIR AND THE SYSTEM MUST BE OPERATING WITH
RELEASE 21 OR HIGHER AND TIL CD RELEASE **1161** OR HIGHER MUST BE INSTALLED.
This bulletin involves selectively erasing and reprogramming the Transmission Control Module (TCM) with new software (calibration changes).
Connect the MDS (Mopar Diagnostic System) and DRB III(R) (Scan Tool) to the vehicle and power them up.
