Refer to the table to identify factory fill and the approved service power steering fluid by year and model. From the table it is noted that the �94 to �02 truck uses part number 04883077/MS5931. MS9602 should not be mixed or used as a �topping off� fluid on systems requiring MS5931.

Category 21 - Transmission

21-11-95	Auto trans	Overdrive unavailable in extreme cold temperatures. The information only bulletin emphasizes a change to the PCM for 1996. For ‘96 in ammbient temperatures of -5°F and below the PCM inhibits the transmission from shifting into overdrive. This protects the transmission from damage if the fluid would begin to freeze. The PCM will allow overdrive once the ambient temperature has risen approximately 7° above the temperature the ID was inhibited at.
21-04-96	All	Transmission will not upshift following a 3-2 downshift. Under certain conditions the transmission will not upshift following a 3-2 downshift. In this condition, the engine will continue to operate at maximum governor speed in second gear until the throttle is reduced. The condition only occurs if the overdrive is “off.” The repair involves reprogramming the powertrain control module with new software.
21-13-96	4wd	Transfer case shifter buzz or clatter. A buzz or clatter may be heard from the 4x4 shifter at an engine speed of approximately 2000 rpm. The repair involves the addition of an insulating plastic gate liner to the transfer case shifter.

21-12-97	All	Transfer case shifter buzz or rattle. This bulletin supersedes TSB 21-13-96, dated 9/20/96. A buzz or clatter may be heard from the 4x4 transfer case shifter at an engine speed of approximately 2000 rpm. The condition may worsen when the engine is under load. On vehicles equipped with automatic transmission the diagnosis must be done with the transmission in overdrive and torque converter clutch engaged. If necessary the correction involves bending the shift lever spring reaction tab outward to increase the spring tension on the shift lever.
21-10-98	Manual trans	Loss of fifth gear. This bulletin supersedes technical service bulletin 21-10-98, with an effective date of September 11, 1998. This bulletin applies to vehicles equipped with a NV 4500 manual transmission and the 8.0L V10 gas engine or the 5.9L Cummins diesel engine. The problem described is that the transmission operates normally through all ranges except fifth gear. The 14 page bulletin describes the proper repair procedure.
21-08-99	All	Buzz, whine or moaning-type noise from a cold transmission when reverse is selected. Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a buzz, whining, or moaning-like noise. The noise is most noticeable when transmission fluid temperature is below 100 degrees F (38C). The condition is caused by a resonance of the transmission regulator valve system. The repair involves replacing the transmission regulator valve.
21-04-00	All	Erroneous MIL illumination for P1763 – Transmission Governor Pressure Sensor Volts Too High. Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 – Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear “limp-In” mode as a result of the DTC. The “Limp-In” mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1, 1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCN) with new software.
21-006-01	Auto trans	Automatic transmission fluid usage ATF+4 (Type 9602). This information only bulletin supersedes technical service bulletin 21-16-99, date October 22, 1999. The bulletin discusses a new transmission fluid (ATF+4 - Type 9602) which has been developed and is being used as factory fill for all vehicles with Chrysler automatic transmissions. Until now, vehicles originally filled with ATF+2 or ATF+3 were to be serviced with ATF+3. Effective immediately, it is recommended that all vehicles with Chrysler automatic transmissions except for 1999 and earlier minivans be serviced with ATF+4. ATF+3 should continue to be used for 1999 and earlier minivans because of the potential for torque converter shudder during break in. For all other applications the ATF+4 fluid offers significant benefits as outlined below. ATF+4 must always be used in vehicles that were originally filled with ATF+4. Service intervals do not change. The service interval currently in effect for a given vehicle should continue to be followed. ATF+4 is compatible with ATF+3 and can be used to top off vehicles that currently have ATF+2 or ATF+3. Do not use ATF+2 or ATF+3 to top off vehicles that have ATF+4 fluid. Benefits: Better wear properties Improved rust/corrosion prevention Controls oxidation Eliminates deposits Controls friction Retains anti-foaming properties Superior properties for low temperature operation Mopar ATF+4 is a World Class Fluid having exceptional durability. However, the red dye used in ATF+4 is not permanent; as the fluid ages it may become darker or appear brown in color. ATF+4 also has a unique odor that may change with age. With ATF+4 fluid, color and odor are no longer indicators of fluid condition and do not support a fluid change.
