On the 2016-2023 Jaguar XF, the ZF 8HP transmission mechatronic unit in the second-generation XF develops internal electrical faults. Failed solenoids and worn valve body bores cause erratic shifting, stuck gears, and transmission fault warnings that put the vehicle into limp mode.

This issue also affects: Acura TL, Mitsubishi Outlander, Acura ILX

Common Symptoms

Transmission fault warning on dash
Vehicle stuck in single gear (limp mode)
Harsh or delayed shifts

How to Fix

Replace or rebuild the mechatronic unit assembly. A ZF-certified rebuild with updated solenoids is more cost-effective than a new unit. Perform a full fluid and filter service simultaneously. Reprogram the TCM after installation.
