NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH 41TE TRANSMISSIONS. IN ADDITION TO THE VEHICLES LISTED
ABOVE, ANY 1989 - 1990 41TE EQUIPPED VEHICLES THAT HAVE HAD A REPLACEMENT CONTROLLER INSTALLED THAT HAS
COOLING FINS, OR IS LABELED WITH P/N 4672104, 4672105, 4672209, OR 4713832 ARE ALSO INCLUDED.
SYMPTOM/CONDITION:
While the temperature of the transmission is -16 F (-27 C) or colder, and the transmission selector lever is placed in any forward gear position, the engine
stalls. This can be the result of ice in the neutral/start switch while the Transmission Control Module (TCM) performs the pump prime test when the
transmission temperature is -16 F (-27 C) or colder.
DIAGNOSIS:
Determine if the ambient temperature could have been -16 F (-27 C) or colder when the transmission lever was placed in a forward gear position.
Assure the shift selector is not binding and is adjusted correctly.
Using the Mopar Diagnostic System (MDS) or the Scan Tool (DRB) with appropriate diagnostic procedure manual, verify that all transmission systems
are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order for future reference, and repair as
necessary. If no codes are present and all systems are functioning correctly, proceed with the following repair.
PARTS REQUIRED:
1 4707123 Switch, Neutral/Start (Park/Neutral)
REPAIR PROCEDURE:
NOTE:
THE SWITCH SEAL WASHER MUST BE PROPERLY SEATED WHEN TIGHTENING THE SWITCH. FAILURE TO DO SO MAY RESULT
IN LEAKAGE OF TRANSMISSION FLUID.
This bulletin involves replacing the park/neutral position switch.
