Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of failure is often erratic or delayed gear shifting. If left unaddressed, the transmission may exhibit persistent fault codes, limp-home mode operation, or fail to engage any gears. Continued operation with a faulty module risks internal transmission damage.

Installation Tip

Always disconnect the battery before removing or installing the control module to prevent electrical damage. Ensure the module's connectors are clean and securely seated to maintain proper electrical contact.

Service Note

When replacing the transmission control module, inspect the transmission fluid level and condition, and check the transmission filter for debris.
