Key Complaint: Poor reverse boost, delayed reverse Secondary Complaint: Low line pressure, poor upshift in manual low Cause: Worn reverse boost valve sleeve or wear at pump body. Vehicles with a 4L60 transmission often have problems with poor reverse boost or upshifts in manual low. These are generally caused by a worn reverse boost valve sleeve or wear at the pump body. Sonnax now offers the larger (.283") reverse boost valve assembly, part number K77898, which restores the hydraulic integrity of the assembly. Due to the differences in the thermal expansion rate of steel and aluminum when the transmission approaches operating temperature, the sleeve has been allowed excessive clearance and scrubs the bore.
- Sleeve and valve are made from hardened steel.
- O-rings added to the boost sleeve seal the reverse boost circuit and prevent leakage
- Sleeve lands have been lengthened to add better sealing and stabilizing capabilities
- The reverse boost valve spool lands have been lengthened
