Wiring shorted to battery or ground, open circuit, or poor connector contact at the solenoid
Failed shift solenoid (coil short or internal mechanical seizure)
Contaminated or low automatic transmission fluid (debris restricting valve operation)
Faulty valve body (sticking spool, bore wear or contamination)
Faulty TCM/PCM or incorrect software/calibration

Check Engine / Transmission warning lamp illuminated
Harsh, delayed or erratic shifting; stuck in a single gear or limited gear range (limp mode)
Reduced fuel economy
Transmission slipping or inability to engage certain gears
Occasional or consistent fault code stored for shift solenoid A

Read DTC and freeze-frame data with a capable scan tool; note conditions when the fault set
Check for related transmission codes (other solenoids, pressure sensors, TCM faults)
Visually inspect the transmission fluid level and condition (color, odour, metal debris)
Inspect connector and wiring to shift solenoid A for corrosion, loose pins, chafing or breaks
Backprobe solenoid connector and command the solenoid ON/OFF with a scan tool while monitoring voltage and ground
Measure solenoid coil resistance and compare to manufacturer specification

Typical solenoid coil resistance (varies by model): approximately 5–50 ohms (check Land Rover spec for exact value)
Activation voltage when commanded: near battery voltage (approx. 10–14 V) on the supply side; switched/ground side is pulsed by TCM
When commanded OFF: expect no ground or 0 V on the switched side (depends on circuit design)
When commanded ON via PWM: duty cycle varies; current draw typically 0.5–2 A depending on solenoid and supply
If stuck ON electrically: continuous ground or voltage present regardless of TCM command; if stuck hydraulically: electrical signals may appear normal while hydraulic pressure/shift response is incorrect

Verify the code and any freeze-frame data with a scan tool. Clear codes and attempt to re-create the fault with a test drive.
Inspect transmission fluid level and condition; top/change fluid and filter if severely contaminated before extensive electrical work.
Visually inspect the solenoid connector and wiring harness for damage, corrosion, or poor pin contact. Repair any damaged wiring or connectors.
Backprobe the solenoid connector. With key on and engine off, measure coil resistance across the solenoid terminals and compare to spec.
With a scan tool, perform an active test: command Shift Solenoid A ON and OFF while monitoring voltage/ground at the connector and observing transmission response.
Check for a short to battery or ground using a multimeter; wiggle the harness while commanding the solenoid to detect intermittent faults.
If electrical tests are within spec but the solenoid/shift response is incorrect, remove and bench-test the solenoid (or replace) and inspect valve body for debris or sticking spools.
If valve body problems are found, clean or replace valve body components as required; replace filter and fluid.
After repairs, clear codes and perform a full road test and re-scan to ensure the fault does not return. Check for any required TCM software updates or relearns.
