Ford 5R55W and 5R55S transmissions commonly exhibit TCC engagement issues, gear ratio codes and overheat problems due to excessive wear in the solenoid feed limit and/or converter feed limit valve bores. Front lube failure and reduced converter charge also may be seen when the converter feed limit valve is worn. Sonnax oversized solenoid and converter feed limit valve kit 56947K-61K and tool kit F-56947J-TL61 refurbish the bore and renew the valve train to restore OE functionality.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
Vacuum tests at the ports indicated fail to hold the recommended minimum of in-Hg.
