Maintenance

Volvo owners manuals list the transmission as fill for life, meaning that there are no scheduled transmission fluid changes under normal operating conditions. This is controversial and believed by some to be a major contributing factor to increased valve body wear, eventually causing transmission problems that require valve body repair or replacement, and possible transmission overhaul or replacement.

Sonnax now provides valve body repair kits that can eliminate the need for expensive valve body replacement.

Transmission experts recommend regular fluid changes, at least every 50,000 miles. Special fluid must be used. If incorrect fluid is used it will result in improper operation and eventual transmission failure.

Fluid

Fluid must meet JWS3309. Dealers carry this fluid under varying designations.
