NOTE: ** This bulletin ONLY applies to vehicles equipped with the 948TE 9 speed
transmission (sales code DFH or DFJ) and whose VIN appears in VIP or on
the RRT VIN list.**
SYMPTOM/CONDITION:
A small number of customers may experience less than desired shift quality during a 5-4
downshift and/or Malfunction Indicator Lamp (MIL) Illumination. Upon further inspection,
the technician may find Diagnostic Trouble Code (DTC) U0402 setting in the Powertrain
Control Module (PCM) memory.
DIAGNOSIS:
**Only perform this repair procedure if the customer’s VIN is listed in VIP or your RRT VIN

transmission/transaxle can become projectiles (E.G., springs, snap-rings,
as well as metal and other debris. Failure to wear safety glasses may
result in severe personal injury.
CAUTION: Tag all snap rings, thrust washers, washers, spacers and thrust bearings,
ect. during disassembly for quick identification and assembly. Failure to
follow these instructions may cause damage to the transmission.
NOTE: Before disassembling the transmission, wash the transmission with a
suitable solvent and/or pressure washer to remove oily grime and loose dirt.
