The ZF-designed 9‑speed automatic used by Chrysler, Jeep, Ram, and Fiat (internal code: 948TE / ZF 9HP48) is known for harsh shifting, gear hunting, delayed engagement, sudden neutral events, limp mode activation, and low‑speed lurching. These issues have persisted across multiple model years despite software updates and TSBs.
Multiple class action lawsuits have alleged defective design, unsafe behavior, and failure to repair the transmission. Several cases resulted in partial settlements, extended warranties, or software update programs.
