Installation & Application Notes

Never run an engine without a filter — even briefly causes abrasive damage. Pre-fill fuel filters with clean fuel before fitting to reduce prime time. Replace O-rings on filter housings every second service. Record change dates on filter housing.

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 dirty transmission filter screen can cause delayed or harsh shifting, and the transmission may exhibit signs of overheating. If the screen becomes completely blocked, hydraulic pressure can drop, leading to a loss of power and potential damage to transmission components.

Installation Tip

Always drain the transmission fluid completely before attempting to remove the old screen to avoid spills and contamination. Ensure the new screen's O-ring or gasket is properly seated before reassembly.

Service Note

Inspect the transmission fluid for excessive metal particles, which could indicate internal wear requiring further investigation.
