Fluid And Filter Service
CAUTION:
A unique transmission fluid has been developed for this transmission. This fluid is NOT compatible with ATF+4 or any other current FCA US LLC transmission fluid. For specifics about this unique fluid refer to appropriate service information FLUIDS, LUBRICANTS AND GENUINE PARTS.
The 948TE/9HP48 automatic transmission is a sealed for life design and does not require periodic service. The only time the transmission fluid needs to be checked is when malfunctions occur or evidence of a transmission fluid leak is present. The fluid filter is mounted internally and requires that the transmission be removed from the vehicle and disassembled to replace the filter. The fluid filter has a plastic body filled with polyester filter fleece.
