P0893 on 2013-2015 Land Rover Range Rover Evoque: Multiple Gears Engaged Causes and Fixes

What's Unique About the 2013-2015 Land Rover RANGE ROVER EVOQUE

The 2013-2015 Evoque range is split by a critical transmission change. The 2013 model uses an Aisin AWF21 6-speed automatic, while the 2014-2015 models introduced the ZF 9-speed (9HP48) automatic. For the 2014-2015 models, Land Rover issued multiple Technical Service Bulletins (TSBs) acknowledging that code P0893 is frequently triggered by a software error in the Transmission Control Module (TCM), not an actual mechanical failure. This makes a software update the most likely fix for these specific years, a unique situation compared to the more traditional mechanical or hydraulic faults expected on the 2013 model.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• "Gearbox Fault" warning message on the instrument cluster
• Vehicle enters 'limp mode' with severely limited power and gear availability
• Harsh, erratic, or delayed shifting
• Inability to select gears with the rotary shifter, or the shifter gets stuck/flashes
• Check Engine Light is illuminated
• Sudden loss of forward propulsion as if shifted to neutral

Most Likely Causes

1. Outdated Transmission Control Module (TCM) Software (2014-2015 Models) 🔴 High Probability Manufacturer TSBs #SSM72164 and #SSM71994 directly identify a 'TCM SOFTWARE ERROR' as the cause for P0893 on the 9HP48 transmission in these models. The bulletins state 'Internal transmission diagnostics have been triggered - issues now resolved', indicating the fix is a software update.
   How to confirm: A Land Rover dealer or specialist with SDD (Symptom Driven Diagnostics) or Pathfinder diagnostic software must connect to the vehicle and check the current software version against available updates. The TSBs specify updating to a specific version or later.
   Typical fix: Update the TCM to the latest available software version and perform a transmission adaptation procedure.
   Est. part cost: $0 (if covered by a service campaign) - $300 for the labor to perform the update.
2. Low or Contaminated Transmission Fluid 🟡 Medium Probability Inadequate fluid pressure is a common cause for hydraulic transmissions to fail to engage or disengage gears correctly, which can be misinterpreted by the TCM as multiple gears being engaged. This is a more likely primary cause for the 2013 model's 6-speed Aisin transmission.
   How to confirm: Check the transmission fluid level and condition. This is a sealed transmission, so checking it requires the vehicle to be level on a lift, at a specific temperature (typically 35-45°C for the 6-speed, 37-45°C for the 9-speed), with the engine running, and removing a check plug until a small trickle of fluid emerges.
   Typical fix: Perform a transmission fluid drain and fill, or a full fluid exchange, using the correct OEM-spec fluid. For the 2013 6-speed, use AW-1 fluid (Land Rover P/N 🎬 Watch: Step-by-step fluid change for the 6-speed Aisin transmission. LR022460). For the 2014-15 9-speed, use ZF Lifeguard 9 / 🎬 Watch: How to properly change fluid on the 9-speed gearbox. Mopar ZF 8&9 Speed ATF (Land Rover P/N LR023288).
   Est. part cost: $200-$500 for fluid and filter/gaskets.
3. Faulty Shift Solenoid or Valve Body (Mechatronic Unit) ⚪ Low Probability
   How to confirm: A technician can perform resistance and voltage tests on the individual solenoids. Diagnosing a faulty valve body often requires advanced pressure testing and may be a process of elimination after software and fluid issues are ruled out. A sticking valve inside the valve body is a common failure point.
   Typical fix: Replace the individual faulty solenoid or the entire valve body assembly. This is a complex job that involves draining the fluid and removing the transmission pan.
   Est. part cost: $500-$1800 for the valve body assembly, plus labor.
4. Internal Transmission Failure ⚪ Low Probability
   How to confirm: This is typically diagnosed after all other possibilities (software, fluid, electronics) have been ruled out. Metal debris in the transmission fluid is a strong indicator of mechanical wear or damage to clutches or gearsets.
   Typical fix: Requires a complete transmission rebuild or replacement.
   Est. part cost: $4000-$8000+

Rare But Worth Checking

• Weak Main or Auxiliary Battery: Land Rover vehicles are known for being extremely sensitive to low voltage. A failing battery can cause a cascade of seemingly unrelated electronic faults, including transmission errors, 'Gearbox Fault' messages, and other spurious codes. This is a simple and relatively inexpensive item to check before proceeding to complex transmission diagnostics.
• Damaged Wiring Harness: Damage to the wiring between the TCM and the transmission can cause communication errors or incorrect signals, leading to this code. A 2016 recall for the ZF 9HP in other vehicles was for an improper wiring harness crimp that could cause a shift to neutral. A visual inspection for chafed, burnt, or corroded wires is worthwhile.

Diagnosis Steps

1. Scan for all stored fault codes to see if P0893 appears with other transmission or communication codes, especially P0795 and P07E3 on 2014-15 models.
2. Check the health, state of charge, and connections of both the main and auxiliary batteries. Low voltage is a common source of electronic gremlins on Land Rovers.
3. For 2014-2015 Models (9-Speed ZF): Your first and most important step is to have a dealer or qualified independent shop with Land Rover's SDD software check for and apply any available TCM software updates, as specified in TSBs SSM72164 and SSM71994.
4. For 2013 Models (6-Speed Aisin) (or if software update on 14-15 models fails): Have a technician check the transmission fluid level and condition. This is a critical step as low or burnt fluid is a common cause of shifting problems.
5. Inspect the transmission wiring harness and connectors for any visible signs of damage, corrosion, or loose connections.
6. If the problem persists, further professional diagnosis is needed to test shift solenoids, the valve body, and internal mechanical components. This is not a DIY-friendly step.

Related Codes That Often Appear With This One

• P0795 — This code for 'Pressure Control Solenoid 'C' Performance/Stuck Off' is listed in the same TSBs (SSM72164, SSM71994) as P0893 for the 9-speed transmission, indicating they can be triggered together by the same software glitch.
• P07E3 — This is another code mentioned in TSBs SSM72164 and SSM71994 alongside P0893, related to transmission faults that can be resolved with a software update on the 9-speed models.

Technical Service Bulletins (TSBs) & Recalls

• SSM72164: Notes that P0893, P0795, and P07E3 can be flagged due to a TCM software error on 2014-2015 Evoque and Discovery Sport models and recommends updating the TCM software using SDD DVD139 Patch 15 or later.
• SSM71994: Also states that P0893 on 14 & 15 MY Evoque is related to internal transmission diagnostics that have been 'resolved' and instructs technicians to update the TCM software and, if the code returns, perform a transmission adaptation procedure.

Platform-Specific Known Issues

• The ZF 9HP48 9-speed transmission used in 2014-2015 models had several well-documented software and hardware issues in its early years across multiple manufacturers, not just Land Rover. This led to multiple TSBs being issued by Land Rover to correct false diagnostic trouble codes, including P0893, with software updates.

Mechanic-Grade Diagnostic Values

• Shift Solenoid Resistance (2014-2015 ZF 9HP48) — expected: 12.5 - 14.2 Ohms. Failure: Readings significantly higher or lower than the expected range indicate a faulty solenoid coil.
• Pressure Control Solenoid Resistance (2014-2015 ZF 9HP48) — expected: 5.3 - 5.6 Ohms. Failure: Values outside this range suggest a failing pressure control solenoid (for clutches B, C, D, E, and TCC).
• Shift Solenoid Resistance (2013 Aisin TF-80SC) — expected: 11 - 15 Ohms. Failure: A reading outside this range points to a bad on/off shift solenoid.
• Linear Solenoid Resistance (2013 Aisin TF-80SC) — expected: 5.0 - 5.6 Ohms. Failure: An out-of-spec reading indicates a problem with one of the pressure-regulating linear solenoids.

Hidden / Shadow Codes Worth Checking

• P0893-07: The '-07' suffix indicates a mechanical failure, such as a component being stuck. While the base code P0893 can be a software glitch, this specific sub-code strongly suggests a physical problem within the transmission (e.g., valve body, clutch) that prevents gears from disengaging correctly. (see via Land Rover dealer-level diagnostic tools like SDD (Symptom Driven Diagnostics) or Pathfinder.)

Scan Tool Commands That Help

• Land Rover SDD / Pathfinder / iCarsoft LR series: Transmission Adaptation Reset / Clear — This function should be performed after a TCM software update, or after replacing the transmission fluid, valve body, or entire transmission. It clears the learned shift pressure values, forcing the TCM to relearn the clutch fill times and pressures for smooth shifting. Failing to do this can result in harsh or erratic shifting even after a successful mechanical repair. The TSB for the software update specifically calls for running the transmission adaptation procedure.
• Land Rover SDD / Pathfinder: Configure New Module - Transmission Control Module — This is required when the entire Transmission Control Module (TCM) is replaced. It programs the new module to the vehicle's specific configuration. This is a separate and more involved process than a simple software update.

Wiring & Ground Locations

• G1D130A — Left front of the engine compartment.. This is a primary ground point for the engine bay, and a poor connection here can affect the Engine Control Module (ECM), which communicates torque data to the TCM. The TSB SSM72164 mentions that the fault can be due to a 'TCM software error and/or engine torque issue', making engine-related grounds relevant.
• G1D108 — Near the battery.. As a main chassis ground near the battery, its integrity is critical for all electronic modules, including the TCM. Poor grounding can cause low voltage conditions or electrical noise, leading to spurious fault codes.
• Transmission Case Connector — On the side of the transmission case. A retainer clip must be removed before the connector can be detached.. This is the main electrical interface between the vehicle's wiring harness and the transmission's internal components (solenoids, sensors). Corrosion or damage to the pins in this connector can directly cause communication loss or incorrect signals, triggering P0893 and other transmission codes.

OEM Part Supersession History

• Unknown → 68197332AA — This is the part number for the internal valve body wiring harness for the 9-solenoid version of the ZF 9HP48 transmission. This harness integrates the range position sensor and speed sensors and can be a point of failure due to heat and vibration, causing various transmission codes.
  Heads up: Ensure you have the 9-solenoid version (mechanical parking brake) and not the 10-solenoid version (electronic parking brake), as the harnesses are different.

Model Year Variations Within This Range

• 2014-2015: TSB #SSM71994 specifies different software file versions depending on the engine. For the DW12 engine, it's 'EJ32-14C337-CBM.vbf' or later. For the GTDi engine, it's 'EJ32-14C337-CAM.vbf' or later. This highlights that even within the 9-speed models, the correct software is engine-specific.
