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

A failing gear may initially produce a noticeable humming or grinding sound that changes with engine speed. This can progress to rough shifting, intermittent power loss, or complete inability to engage certain gears. Continued operation risks severe damage to other transmission components.

Installation Tip

Ensure proper lubrication of the gear teeth and shaft splines before assembly to prevent initial wear. Do not mix old and new gears if multiple are being replaced without careful inspection of the old ones.

Service Note

Inspect the transmission oil for metal particles and check all mating gears and bearings for wear when replacing this component.
