Dealers can fix some parts of the nine-speed transmissions, but should not try to rebuild them, according to a recent FCA US notice to dealers.
The document indicates that problems with the Jeep Cherokee’s nine-speed were reduced in 2015, as there is a special process for dealing with model-year 2014 and early 2015 V6 Cherokees (built through March 3, 2015). Dealers are supposed to request a transmission replacement electronically, supplying images of the transaxle serial number, odometer, and diagnostic worksheet. There is a replacement worksheet as well, which is required, and notes the “repair issue.”
There are differences in what can be repaired on the ZF-build 9HP48 and Chrysler-built 948TE versions. Dealers can fix the oil feed tube, cover kit and gasket, differential seals, access hole plug, and valve body on both, along with replacing the torque converter. On the 948TE, dealers can also replace the oil pan and transmission range sensor.
Dealers do need pre-authorization to get a replacement transmission, but they are not allowed to take apart transmissions except to replace the parts above. When transmissions are replaced, the FCA system will note that the nine-speed has been replaced by one with “commonized hardware [and] software.”
