Recall roundup – ZF to service 505,000 nine-speed transmissions image

One of the largest automotive suppliers in the world – ZF – has announced a safety campaign for 505, 000 nine-speed automatic gearboxes because they could shift into the neutral position.

The company said the issue can occur without warning and it appears the fault lies with the wiring harness. According to the company’s report to the National Highway Traffic Safety Administration, the “insufficient crimps” in the wiring harness for the Transmission Control Sensor Clusters are causing the problem. This latter part is responsible for helping control the shift pattern, with the affected components being manufactured between May 1, 2013, and July 15, 2014.

The supplier first caught wind of the issue back in July 2014 when a supplier reported a single failure during transmission testing – but at the end of last year Fiat Chrysler Automobiles reported even more field reports about the issue. ZF started addressing the problem and has developed a software update. The issue lies with the company’s model 9HP48 or 948TE gearboxes, which are used in vehicles from the Honda, FCA, and Land Rover brands, including brand new generations such as the Chrysler Pacifica. The supplier will first contact the automakers, which deploy separate recalls for the affected vehicles. Dealers will then install software to “prevent the transmission from shifting into neutral due to a faulty crimp.”
