Product Description
Vehicles with 6L45 6L50 6L80 6L90 transmissions may exhibit insufficient line rise in drive ranges, soft shifts and/or burnt clutches. These problems may be caused by continuous oscillation of the boost valve within the boost sleeve, creating excessive wear and a path for EPC fluid pressure to leak to exhaust. Sonnax boost valve kit 104520-01K has upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control. The sleeve also has a slightly larger EPC feed orifice to provide quicker throttle response.
- Boost sleeve is manufactured from highly wear-resistant billet aluminum to prevent wear
- Larger feed orifice provides quicker throttle response
- Restores proper line rise
