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.
