The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

Important: Depending on the ECU type and vehicle model, not all of the options listed below may be available.
To select the correct option for your vehicle and ECU, please contact us before purchasing:
contact@auto24parts.com
1. Locked
This option is intended for professional workshops with the required specialist equipment and technical knowledge.
The ECU has been removed from a vehicle intended for recycling and still contains the immobilizer data and other information from the previous vehicle. Before it can be used in another car, it must be unlocked and then programmed using specialist automotive diagnostic equipment.
2. Unlocked
Several preparation methods may be available. The possible options depend on the ECU type, vehicle model and immobilizer system. Please contact us before purchasing, as some preparation methods are not available for every ECU.
Our electronics specialists can prepare the ECU in one of the following ways:
a) ECU with PIN code (Car Pass)
The PIN code is supplied, but programming with a suitable diagnostic tool is still required. After installing the ECU, it must be reset using the supplied PIN code and then programmed to the vehicle’s immobilizer system.
b) VIRGIN ECU
The data from the previous vehicle is removed and the ECU is restored to a clean, factory-like state. After installation, it must be programmed to the vehicle using a compatible specialist diagnostic tool. Unless another preparation method is specified in the product description, this is the standard unlocking option for most of our ECUs.
c) Plug & Play – IMMO OFF
The immobilizer function is disabled in the ECU. After installation, the engine can start without additional immobilizer programming. Please note that the vehicle will no longer have an active immobilizer function, and an immobilizer warning light or fault code may remain, depending on the vehicle model.
d) Plug & Play – Automatic Programming
After installation, the ECU automatically learns and saves the required vehicle data. No additional programming is normally required.
e) Plug & Play – 1:1 Clone
The data from your original ECU is copied to another fully functional ECU. The cloned unit is then ready for installation without additional programming.
You must send us your original ECU so that we can transfer its data to the replacement unit.
The original ECU must have working communication with the vehicle, a diagnostic tool or our programming equipment. If the required data cannot be read, a complete 1:1 clone may not be possible.
3. Complete Plug & Play Set
A complete matched set containing the ECU, immobilizer components and all other parts required to start the vehicle without additional programming. All components supplied in the set must be installed in the vehicle.
Important:
Dispatch time depends on the selected option. If an unlocked or specially prepared version is ordered, the preparation service usually requires an additional 1–2 business days.

Will the 37820-PK2-6020 ECU fit your Honda?
A working, used ECU with numbers 37820-PK2-6020 and 37820PK26020. Compare them with the label of your own unit; we agree the unlocking method before purchase.
Engine control unit Honda 37820-PK2-6020 37820PK26020
This used 37820-PK2-6020 engine computer for Honda vehicles processes sensor signals and calculates the engine’s operating parameters. We do not state a model or engine that the label does not confirm; the part numbers decide the fit.
Numbers to check
- 37820-PK2-6020 – Honda part number
- 37820PK26020 – the same number without the dash
Every character must match, including the final letters. If you are not sure, send us a photo of the label.
When the ECU may be faulty
- the engine will not start despite a good power and fuel supply,
- no communication with the ECU during diagnostics,
- limp mode with no sensor fault,
- damage after water ingress or a voltage spike.
Before replacing the ECU, check the power supply, earths and wiring loom – a damaged wire or connector can cause similar symptoms.
Locked or unlocked version?
A locked ECU holds the data and immobiliser of the previous car – it is chosen by garages that will program it themselves. The unlocked version is prepared by us before dispatch.
We agree the preparation method case by case – it depends on the software version and the immobiliser. Ask us about it before ordering the 37820-PK2-6020 ECU.
All variants are described on our Locked & Unlocked ECUs page.
Frequently asked questions
| Can I fit an ECU with a different number suffix? |
|---|
| A different suffix can mean a different software or hardware version. Send us a photo of the label and we will check whether the 37820-PK2-6020 ECU is suitable. |
| Will the ECU start the engine straight after fitting? |
| The locked version will not – it needs programming and matching to the immobiliser. With the unlocked version it depends on the preparation method, which we agree before purchase. |
| What condition is the ECU in? |
| It is a used part, fully working and in good condition. The warranty period is shown in the product features table. |
Not sure which variant to choose? Email contact@auto24parts.com with the numbers from your label – we will check the available options.
