Quick answer
The Jetour T2 i-DM plug-in hybrid uses a 3-speed dedicated hybrid transmission (DHT) that combines the SQRH4J15 1.5T engine with electric motors, and the car has four-wheel drive. Jerks when the engine joins in, clunks, whining, a drive-system warning or limited power can indicate a control or software issue, a sensor fault, fluid condition, worn mounts or an internal DHT fault. Because the DHT sits next to high-voltage components, diagnosis belongs with a qualified workshop trained in hybrid systems; ShipMyPart can source VIN-matched parts.
What the T2 i-DM transmission is
| Fact | Jetour UAE (2027 sheet) |

Symptoms owners describe on a hybrid transmission
| What happens | When it tends to show |
|---|---|
| A jolt or surge | As the petrol engine starts and joins the electric drive, or as the DHT changes ratio |
| Clunk on take-up | Selecting D or R, or lifting off and back on the accelerator |
| Whine or hum that rises with speed | In EV mode, when other noise is low |
| Drive-system or hybrid warning, reduced power | Often after heat, hard 4WD use or a low battery state |
| Engine revs without matching acceleration | Under load, uphill or in sand |
| No drive in one direction | Any time; treat as urgent |
Some engine starts and stops are normal on a plug-in hybrid. What matters is a change from the car's usual behaviour.
Possible causes in a DHT plug-in hybrid
Possible causes include:
- Control software and calibration. The hybrid controller decides when the engine joins and which ratio is used; outdated or corrupted settings can cause jerks. A workshop checks for updates.
- Sensor or wiring faults giving the controller wrong speed, position or temperature data.
- Fluid condition or level in the DHT, which lubricates and may also cool internal parts.
- Engine and transmission mounts worn by the high torque of the combined system, causing clunks.
- Shift selector faults that misreport the chosen position.
- Internal DHT wear or damage to gears, bearings or the units that couple the engine, found only by a specialist.
- A fault elsewhere in the electric drive, such as a rear motor issue, that the car reports as a drive problem.
Transmission-related parts on the T2 i-DM
The complete DHT unit and its internal parts are identified by VIN on request. Related parts:
- Control modules: engine, transmission and related controllers; replacement usually needs coding by a workshop.
- Transmission filter: if the DHT uses one, it is normally changed with the fluid; the VIN confirms it.
- Mounts and bushings: carry the engine and DHT and absorb the system torque.
- Shifter assembly: the drive selector in the cabin.
Clutch kits, multi-speed automatic units and similar items for other gearbox types are left out here because they do not match this powertrain.
Owner notes, not owner repairs
- Photograph any warning and note the battery charge level shown at the time.
- Note the driving mode (EV, hybrid, 4WD or terrain mode) and whether the symptom changes between them.
- Record whether it happens cold, after charging, after a long drive or only in heat.
- Note whether the jolt coincides with the petrol engine starting.
- Check for fresh fluid spots under the car after parking.
Do not open plugs on the DHT, and do not disconnect any orange high-voltage cable or connector. Even with the car switched off, high-voltage parts can stay dangerous.
Workshop diagnosis and urgent situations
A qualified workshop with technicians trained in high-voltage systems and with suitable diagnostic software can read hybrid and transmission codes, check software level and test the motors and DHT. Book one if jolts, noises or warnings repeat.
Stop safely and arrange recovery if the vehicle loses drive, will not engage D or R, shows a message telling you to stop, or gives off a burning smell. Ask the recovery operator to transport the car on a flatbed, since a 4WD hybrid with drive at both axles should not normally be towed with wheels on the ground; your owner manual gives the exact instruction.
UAE desert and summer use
With 600 hp of system output and 915 N·m on paper, a T2 i-DM in soft sand can put very high loads through the DHT, mounts and rear motor. Repeated launches on dunes, long climbs and towing in summer heat add stress and temperature. If the car reduces power during desert use, let it cool rather than pushing on, and mention the conditions to the workshop afterwards. In city traffic, frequent engine starts and stops are part of normal hybrid operation.
Ordering DHT-related parts
Tell ShipMyPart the VIN and what the workshop found: a control module, a mount, the selector, the filter, or a complete DHT assembly. We confirm the T2 i-DM version, match the part, quote it and deliver in the UAE. Where a part needs programming, plan that with your workshop before ordering. Fluid details are in the Jetour T2 i-DM transmission fluid guide.

Frequently asked questions
What gearbox does the Jetour T2 i-DM have?
Jetour UAE lists a 3-speed dedicated hybrid transmission (DHT), working with the SQRH4J15 1.5T engine and electric motors, with four-wheel drive.
Why does my T2 i-DM jolt when the engine starts?
Possible causes include control software, a sensor fault or worn mounts. A workshop with hybrid diagnostic software should check it.
Is it normal for the engine to start and stop on its own?
Yes, on a plug-in hybrid the engine starts and stops as needed. A jolt, noise or warning with it is worth checking.
Can I tow my T2 i-DM with the wheels on the ground?
Check the owner manual; for a 4WD hybrid, flatbed transport is usually the safe option.
Which fluid does the DHT use?
Jetour UAE does not publish the DHT fluid type or quantity. Check the owner manual or send us your VIN.
Can ShipMyPart supply a complete DHT unit?
After a VIN check we can try to source the DHT assembly or related parts and quote with UAE delivery.
