Installation & Application Notes

Drain and replace transmission fluid when servicing internal components. Use correct ATF specification. Pre-fill torque converters with fluid before installation. Allow 10 minutes for fluid to settle before checking level.

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

Failure Symptoms

Initial signs of a failing clutch include gradual loss of power, especially under load, and a tendency to slip. If ignored, the clutch may begin to chatter or make grinding noises during engagement, eventually leading to an inability to transfer power to the drivetrain. Continued operation with a severely worn clutch can result in transmission damage.

Installation Tip

Ensure the flywheel surface is clean and free of oil or debris before installation. Avoid overtightening clutch bolts, as this can warp the clutch components.

Service Note

Inspect the transmission fluid and filter for any signs of clutch material contamination.
