Symptoms:

Flare shifts
Pressure control out-of-range codes
Low line pressure

Cause:

Bore wear at the VFS1 (PCA) and VFS2 (PCB) locations allows modulated line pressure to exhaust instead of feeding the overdrive, intermediate or low/reverse servos or the coast clutch. Fluid pressure loss at these apply components results in low line pressure, shift complaints and burnt clutches and bands.

Correction:

这个Sonnax工具包允许穿to be eliminated, future wear to be prevented and correct hydraulic pressures to be restored to critical apply components. The kit works in either modulator control bore location.

In Ford 5R55W and 5R55S transmissions, bore wear at the VFS1 (PCA) and VFS2 (PCB) locations allows modulated line pressure to exhaust instead of feeding the overdrive, intermediate or low/reverse servos or the coast clutch. Fluid pressure loss at these apply components results in low line pressure, shift complaints and burnt clutches and bands. The Sonnax VFS modulator control sleeve and valve kit 56947J-19K allows correct hydraulic pressures to be restored to these critical apply components.

Wear-resistant sleeve provides additional support to the control valve
Valve is hardcoat anodized to reduce wear and has more sealing contact with the bore than OE to minimize leakage.
O-ringed end plug provides positive seal to the bore once valve/sleeve assembly is installed.
Spring maintains OE operating pressures.

Note

Kit works in either the VFS1 or VFS2 modulator control bore location.
