Some common complaints associated with Ford 5R55N, 5R55W and 5R55S transmissions are high TCC slip, slip codes 741, TCC lining degradation and converter apply or release concerns. These complaints are often caused by wear at the TCC control valve casting bore. Although the control circuits used to stroke the control valve in the 5R55N differ from the 5R55W and 5R55S units, the TCC control valve is the converter oil switch valve, ultimately directing converter apply or release oil in both designs. Sonnax oversized TCC control valve kit 56947J-05K works in the 5R55N, 5R55W and 5R55S, and allows the valve body bore to be refurbished to restore proper TCC modulator/apply circuit fluid pressure control.

Precisely toleranced parts restore proper TCC modulator/apply circuit pressure control
Hardcoat anodized aluminum valve combats premature wear
Valve incorporates the balance line feed hole used in the 5R55N OE design
One replacement valve fits both 5R55N and 5R55W and 5R55S applications

Note

The modulator sleeve and inner modulator valve must be inspected for probable bore wear.
