Common Issues with FAW J7 Automatic Transmission?
2 Answers
The common issues with the FAW J7 automatic transmission include steering deviation and engine oil leakage. Additional information: The FAW J7 is equipped with the FAW Aowei CA6DM2-46E6 National VI heavy-duty diesel engine, a specialized engine for the J7 with an 11L displacement, 460 horsepower, and a maximum torque of 2300 N·m. The after-treatment system features EGR+DOC+DPF+SCR, fully compliant with National VI emission standards. It uses the FAW self-produced CA12TA230A5 AMT transmission, which has an all-aluminum housing and is paired with a Voith hydraulic retarder. For the chassis, this vehicle adopts the new F5N front axle (Cummins hub) and a rear 435 welded axle (Cummins hub, WABCO ABS system, and equipped with an inter-wheel differential lock), with a gear ratio of 2.867.
As a veteran driver who has been driving the FAW J7 for years, hauling cargo over thousands of kilometers, the common issues with automatic transmissions mainly involve rough gear shifting and frequent stalling when climbing hills, which can lead to increased fuel consumption and driver fatigue. I've encountered high oil temperature warnings, especially after long summer trips, likely due to insufficient cooling system design. Oil seal leaks are also frequent – immediate repair is crucial to prevent internal component damage. I recommend changing transmission oil every 30,000 kilometers; don't cut corners on maintenance. Additionally, occasional cold-start shaking might indicate minor sensor faults – regularly check wiring connections. Preventing these issues ensures greater vehicle durability and saves significant repair hassles.
