Defective ZF Transmission Sensors Recalled in 505,000 Vehicles

ZF North America is recalling over 500,000 of its 9-speed transmissions (number 9HP48 or 948TE) because they can suddenly slip into neutral.

The problem is caused by a terminal crimping issue with 26-way connectors on the sensor cluster harness assemblies.  The company says the star-shaped connector was not properly crimped and the problem wasn’t caught at the factory because of a manual setting used for measurements.

Fiat-Chrysler beat ZF to the punch by announcing their recall for this problem at the end of last month.
