Technical Data and Architecture

Navigating modern transmission diagnostics requires precise reference material. This factory documentation maps out structured diagnostic paths for both the automatic transmission and its broader electronic control network. It clearly defines Transmission Control Module (TCM) functions. You will find comprehensive testing procedures covering critical signal monitoring, such as accelerator pedal position, turbine revolution, and specific gear shift timings. Furthermore, the material breaks down complex Diagnostic Trouble Code (DTC) analysis and circuit verification steps for the transmission solenoid bank. This allows technicians to pinpoint electrical faults efficiently rather than relying on guesswork.

Specification Highlights

Accurate system validation relies heavily on exact factory metrics. The manual provides essential technical specifications, including baseline hydraulic pressure values, precise fluid capacities, and expected sensor signal data. For standard maintenance, transmission fluid capacity is documented at exactly 10.3 US qt. When running diagnostics, mechanics can reference the specific line pressure test values, which are listed at 379–428 kPa in the D position at idle. Working on high-pressure transmission systems and electronic components carries inherent risks, so please ensure that all service work is performed or supervised by a certified technician.
