Various TCC concerns and lube failures are common problems with Ford 6R140 transmissions. These issues can often be traced to excess wear in the converter limit valve bore, which allows escape of crucial circuit control pressures. Reconditioning the bore and installing Sonnax oversized converter limit valve kit 126740-19K eliminates this wear and revives normal TCC and lube operation.
