Maintenance Recommendations

Preventive maintenance to extend transmission life and prevent problems.

  1. Change transmission fluid every 30,000 miles with Honda MTF or equivalent
  2. Use synthetic transmission fluid for better high-temperature performance
  3. Avoid aggressive shifting and quick clutch engagement
  4. Allow transmission to warm up in cold weather before hard driving
  5. Regularly inspect clutch hydraulic system for leaks
  6. Check transmission mounts and engine mounts for wear
  7. Consider aftermarket transmission cooling solutions for track use

Important: Proper maintenance can significantly extend transmission life and prevent major failures.

Cost Estimates

Typical cost ranges for transmission-related repairs and maintenance.

Owner Experiences

Common experiences and feedback from 2003 Acura CL Type S owners.

"My 2003 CL Type S started grinding in 2nd gear at 65,000 miles. The dealer quoted $2,800 for transmission rebuild. I found an independent shop that did it for $1,900 with upgraded synchronizers."

"The clutch master cylinder failed at 50,000 miles. Replacement solved the shifting issues temporarily, but the transmission still grinds when cold."

"After switching to synthetic transmission fluid and installing a short shifter, the shifting improved significantly, though some notchiness remains in cold weather."

Consensus: Most owners recommend proactive maintenance and considering aftermarket upgrades for long-term reliability.
