Limp modePossible
P0893 means more shift elements are applied than the commanded gear allows, so the gearbox binds up. It is detected through speeds, when the ratio matches no valid gear and input speed collapses, or through commanded clutch capacities: a GM patent flags capacities above their limits for longer than roughly 200 to 500 ms and reacts by downshifting or falling back to the hydraulic limp mode. Nissan's 2020–22 Frontier and Titan nine-speed set it with all ratio codes and MIL; Land Rover cured P0893 on the ZF 9HP48 Evoque with gearbox software.
Likely causes
Gearbox module software or calibration
Shift or pressure valve sticking (dirt), control valve body faulty
Clutch plates stuck or welded
Speed sensor false signal
Symptoms
- Gearbox or engine warning lamp
- Sudden limp mode, harsh jolts or judder
- Strong braking or locking feeling during a shift
