Oversized valve 3-4 4T65E Volvo
- Valve
- Spring
Volvo only
To help control the 4th clutch apply pressure and shift feel, a 3-4 accumulator piston and an accumulator valve regulatingfluid pressure are used. The 3-4 accumulator valve regulates line pressure using torque signal influence, and directs 3-4 accumulator pressure to the spring side of the piston, controlling the 4th clutch apply. Wear at the bore or valve can allow torque signal, 3-4 accumulator or line pressures to exhaust, resulting in various 3-4 shift complaints.
Symptoms:
3-4 Concerns Soft shifts & poor line rise
Cause:
Wear at the 3-4 accumulator valve and/or bore, allowing loss of torque signal, 3-4 accumulator and/or line pressure.
Correction:
Refurbish the worn bore and install the Sonnax oversized valve to restore correct hydraulic clearances and shift control.
