G4A-EL, G4A-HL, GF4EAT

No TV cable, electronic transmissions, Factory style sleeve, no o-rings

Symptoms:

• Low line rise
• Low line rise in Reverse & shudder
• 1-2 Quality poor
• Delayed Reverse

Cause:
Worn boost valve sleeves allow EPC, TV boost or reverse pressures to cross leak into exhaust.

Correction:
These replacement boost valve kits are hardened and anodized to prevent wear and are tightly toleranced to restore the hydraulic integrity of the circuits.

Warning:
The applications listed above are meant as a guide only. Be sure to measure original valve and compare dimensions before purchasing.

Vehicles with a G4A-EL or GF4A-EL, F4A-EL, or F4EAT transmission may have problems with low line rise or low reverse boost. These problems can be caused by worn boost valve sleeves that allow EPC (GF4A-EL F4A-EL, F4EAT), TV boost (G4A-EL F4A-EL, F4EAT), or reverse pressures to cross leak or leak to exhaust. Sonnax has developed replacement boost valve kits for both the G4A-EL, and the GF4A-EL, F4A-EL, and F4EAT 74846-01K.

• The GF4A-EL boost valve is made from anodized aluminum, and the sleeve is manufactured from high-quality aluminum to resist wear.
• The 74846-01K GF4A-EL kit has been modified to fit the F4A-EL and F4EAT applications, and allows for more responsive EPC pressure.

Note:
No TV Cable/with Electronic Transmission
