Section 11 (8HP95 Automatic Transmission (Service Information)): Assembly

WARNING: This page is about a different variant/trim than selected.
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 see CAPACITIES AND RECOMMENDED FLUIDS .

CAUTION:

The Transmission Control Module (TCM), or Transmission Control Module Assembly (TCMA) is extremely sensitive to Electrostatic Discharge (ESD). Always use a ground strap and follow the ESD guidelines in ELECTROSTATIC DISCHARGE SENSITIVE DEVICES. Failure to follow these instructions may result in damage to the TCM/TCMA.

NOTE:

If the transmission is being reconditioned (clutch/seal replacement) or replaced, it is necessary to perform the Transmission Control Module (TCM) Adaptation Procedure. Refer to TRANSMISSION CONTROL MODULE (TCM) ADAPTATION .
