Causes

  • Open, short to ground, or short to battery in the solenoid harness
  • Corroded, loose, or damaged solenoid connector
  • Failed transmission shift/change solenoid (D)
  • Blown fuse or poor battery/ignition power supply
  • Faulty transmission control module (TCM) or PCM output driver
  • Internal transmission wiring fault or circuit board issue

Symptoms

  • Check Engine or Transmission MIL illuminated
  • Harsh, delayed, or erratic shifting in affected gears
  • Transmission may default to limp/limited shift mode
  • Vehicle may be stuck in a single gear or refuse to shift into Drive properly
  • Possible unusual transmission noise or degraded performance

What to check

  • Read freeze frame and live data with a calibrated scan tool; confirm P0982 and any related codes
  • Visually inspect harness and connector at the transmission solenoid pack for corrosion, damage, or moisture
  • Check relevant fuses and battery/ignition supply voltage
  • Backprobe solenoid connector and measure control voltage while commanding solenoid on/off from scan tool
  • Measure solenoid coil resistance and compare to factory spec
  • Perform wiggle test of harness while monitoring voltage/continuity for intermittent faults

Signal parameters

  • Control driver output: typically a switched/PWM duty from 0 V (off) to battery voltage (~12 V) when commanded — verify with factory data
  • Expected solenoid coil resistance: commonly ~20–60 Ω (varies by model) — consult Land Rover specification
  • Supply voltage at connector (key ON): battery voltage (~12 V) present on supply pin
  • Ground continuity: near 0 Ω from solenoid ground to chassis/TCM ground when measured with harness disconnected
  • When commanded ON, control line should show a change in voltage or PWM duty cycle as specified by the TCM

Diagnostic algorithm

  1. Confirm code and capture freeze frame/live data. Note battery voltage and operating conditions when the code set.
  2. Visual inspection: battery condition, fuses, wiring, and connectors at the transmission solenoid pack for damage or corrosion.
  3. With ignition ON, backprobe the solenoid connector. Verify reference/supply voltage is present and stable (battery voltage).
  4. Command the D solenoid ON/OFF using a scan tool while monitoring control wire voltage and PWM. Document responses.
  5. Measure solenoid coil resistance with connector disconnected. Compare to factory spec; infinite/low resistance indicates open/short.
  6. Check continuity from TCM output pin to solenoid connector pin. Check for short to ground or battery using an ohmmeter/short tester.
  7. Perform wiggle/functional test along harness while monitoring for intermittent changes. Repair damaged wiring or connector terminals.
  8. If wiring and solenoid check good, substitute a known-good solenoid or control module if available and retest.
  9. If fault persists after harness and solenoid replacement, test or replace the TCM/PCM output driver according to Land Rover procedures.
  10. Clear codes and perform a road test under similar conditions to verify repair. Re-scan for related codes.

Likely causes

  • Damaged or corroded connector at transmission solenoid pack
  • Short to ground in wiring between TCM and solenoid
  • Failed D change/shift solenoid coil
  • Weak or missing fused ignition power or poor ground at transmission
  • Faulty TCM (less common)

Fault status

⚠️ Status
P0982 — Low D control circuit for transmission change/shift solenoid. Low voltage, short to ground, open circuit, or driver fault detected. May cause abnormal shifting or limp mode.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1.0-3.0 hours
