Test electronic control, hydraulic pressure, clutch/converter and mechanical driveline behaviour separately.
Temperature and fluid level/condition can directly affect pressure regulation and adaptation behaviour.
Verify software, mechatronic and ratio variants within the same family by exact application/part identity.
TRANSMISSION DIAGNOSTIC FLOW
Measurement sequence
Confirm exact transmission code and software/application variant.
Verify fluid level, condition and temperature.
Capture input/output speeds and actual ratio.
Test electronic command, hydraulic pressure and mechanical clutch separately.
Verify shift/adaptation result under load.
Source-verified powertrain relationships
No curated engine-transmission relationship is present in the source graph for this family yet. Exact fitment is not inferred.
OEM EVIDENCE DOSSIER
Verified technical facts and application boundary
Stellantis e-DCS6 combines a six-speed dual-clutch transmission and electric motor in one electrified drive package.[S1]
Manufacturer documentation describes the electric motor, inverter and control electronics as integrated with the transmission architecture.[S1][S2]
Because 48 V battery and engine torque are coordinated with e-DCS6 clutch/shift control, diagnosis cannot be reduced to mechanical ratio data alone.[S2]
Verified application matches
The matches below are published only within the stated market, model-year and evidence scope. Fitment is not extrapolated to uncited variants.
If an electric motor is integrated into the transmission, correlate motor torque request, inverter voltage/temperature and clutch transition through the same shift.
DTC / SPN-FMI / symptom discrimination map
For a shift fault verify actual ratio from input/output speed first, then separate clutch slip/temperature from actuator command.
Where electric torque assistance is present, correlate engine/e-motor torque coordination with clutch state through the shift event.
If network or low-voltage DTCs accompany the complaint, rule out supply/CAN events before condemning mechatronic hardware.
Measurement and diagnostic strategy
Before clearing DTCs record input/output speed, commanded/actual gear, clutch slip/temperature, actuator state and engine torque request.
Independently verify supply voltage and CAN integrity before condemning mechatronic hardware; use only OEM test ports/procedures for hydraulic/oil pressure.
After repair repeat the same cold/hot shifts and compare slip and torque coordination.
Exact pinouts, torque values, pressure thresholds or service limits are published only when explicitly verified by the applicable OEM service source.
Only the application and technical architecture explicitly verified by the OEM sources below for Renault/Stellantis e-DCS6. Fitment is not extrapolated to uncited model years, markets or variants.

Exact pressures, torque values, pinouts, fluids, adaptations and part procedures must be confirmed against the VIN/build-date/unit-code matched manufacturer service information.
