When should I replace the transmission filter and what symptoms indicate issues?

Replace the filter during scheduled transmission service intervals or when symptoms appear that suggest flow restriction or contamination. Signs that the filter needs attention include unusual transmission noise, leaks, rough or delayed shifting, and fluid contamination or discoloration.

• Inspect during routine ATF change or if shifting becomes harsh or erratic.
• Look for metal particles or dark, burnt fluid as indicators of internal wear.
• Replacing the filter proactively can help avoid more costly valve body or clutch repairs.
