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 planet gear typically first presents as an audible grinding or whining noise during operation, especially under load. This can progress to a noticeable power loss or vibration, and eventually, the inability to transmit power effectively through the transmission.

Installation Tip

Ensure proper lubrication of the gear teeth and associated bearings before installation to prevent initial wear. Avoid forcing the gear into place; it should seat smoothly if aligned correctly.

Service Note

Inspect the ring gear and sun gear within the same planetary set for any signs of pitting, scoring, or excessive wear.
