4. Thermal Management: The Cooler Head Prevails

• Overheating / burnt fluid: Caused by heavy stop-start duty or clogged cooler — remedy: inspect/clean cooler, ensure correct fluid, consider increased cooling capacity.
• Shift harshness or slip: Could be low/contaminated fluid, worn clutch packs or incorrect TCU adaptation — remedy: fluid change, TCU reset/adaptation, mechanical inspection.
• Electronic faults / error codes: Often due to CAN communication issues, sensor faults or TCU software — remedy: read fault codes with ZF-compatible diagnostic tool, check wiring/connectors, update TCU firmware.
• Leaking seals: Replace worn seals and inspect mating surfaces. Use correct torque values on pan and casing bolts.
