Common problems with Ford 6R140 transmissions include TCC apply and release concerns, TCC codes, burnt TCC lining, overheated fluid and lube failures. In extreme cases, converter release may be prevented, resulting in engine stalling. These symptoms can be caused by pressure loss due to excess wear at the TCC charge limit valve and bore. Reconditioning the bore and installing Sonnax oversized TCC charge limit valve kit 126740-01K restores hydraulic integrity of this circuit for renewed TCC and lube operation.
