P08E1 Shift Solenoid L Electrical

Check engine lightOn

EmissionsRelevant

Drive cycleNot required

Limp modePossible

General electrical malfunction of shift solenoid L, intended for transmissions whose TCM does not distinguish or separately report low, high and open circuit faults. No manufacturer documents this code publicly. The equivalent electrical code is in real use for lower letters, for example P2709 for shift control solenoid valve F on the 2017 and 2018 Genesis G80 and G90 8-speed, where Hyundai's bulletin 21-AT-016HG calls for harness checks and solenoid replacement. Ford fails a solenoid electrically when the driver feedback disagrees with the command for 0.5 to 5 seconds. CARB requires the circuit check. P08E3 to P08E6 are the detailed codes, P08E2 the intermittent one.

Likely causes

Solenoid L coil failed electrically

Harness or connector damage on the solenoid circuit

TCM output fault

Symptoms

Check engine or transmission warning light on
Harsh shifts or fixed gear
Reduced driving performance

Repair estimate

DifficultyHardWorkshop job

Parts and labour€100–1,500

Time1–5 h

Typical range across vehicles; the real cost depends on what the testing finds.
