6 / 8-Speed Automatic
Conventional torque-converter automatics use valve-body, solenoid, converter and internal clutch systems. Exact speed/unit varies by engine and build.

Specialist diagnosis, repair and reconditioning for Vauxhall Grandland automatic transmissions, covering first-generation conventional six-/eight-speed automatics, electrified eight-speed PHEV applications and the current six-speed Hybrid dual-clutch powertrain.
If your Grandland shudders, delays into Drive, slips, shifts harshly or shows a transmission warning, we identify the exact generation and Hybrid/Electric specification before repair.
Grandland X/first-generation models used conventional automatics including an eight-speed on later petrol/diesel versions, while Hybrid4 paired its front motor with an electrified eight-speed automatic. The second-generation Grandland Hybrid uses a six-speed dual-clutch transmission with an integrated electric motor. Grandland Electric uses a reduction drive.
| Grandland generation / type | Typical UK versions | Automatic gearbox | What owners often search for |
|---|---|---|---|
| Grandland X, 2017–2021 | 1.2 Turbo / diesel automatic versions | Conventional 6-/8-speed automatic depending on engine/build | Grandland X auto fault, delayed Drive, valve body |
| Grandland facelift, 2021–2024 | Petrol/diesel and Plug-in Hybrid variants | 8-speed automatic on relevant combustion/PHEV versions | Grandland 8-speed shudder, PHEV gearbox warning |
| New Grandland Hybrid, 2024–present | 1.2 48V Hybrid | Electrified 6-speed dual-clutch automatic | New Grandland Hybrid DCT fault, clutch judder |
| New Grandland Electric | Battery-electric versions | Single-speed electric reduction drive | Grandland Electric drive-unit fault |
Conventional torque-converter automatics use valve-body, solenoid, converter and internal clutch systems. Exact speed/unit varies by engine and build.
The original plug-in-hybrid pairs the front electric motor with an electrified eight-speed automatic, requiring both hybrid and transmission diagnosis.
The 48V Hybrid uses an electrified six-speed dual-clutch transmission with an integrated electric motor. Clutch and hybrid-control data should be read together.
Grandland transmission symptoms can overlap with hybrid transitions and, on Electric versions, drive-unit behaviour, so the powertrain must be identified before repair.
On electrified dual-clutch versions, low-speed judder can involve clutch engagement, adaptation, actuator control or hybrid powertrain transitions.
A pause after selecting gear can involve clutch application, hydraulic/electronic control, conventional-auto pressure or internal wear depending on the transmission.
Abrupt shifts can involve adaptation, valve-body pressure control, DCT clutch control or internal mechanical damage.
A transmission or hybrid warning should be scanned across both gearbox and electrified powertrain control modules before parts are replaced.
On conventional automatics this can involve clutch or pressure loss; on DCT versions it can involve clutch wear or actuator/control faults.
Transmission, electric-drive, mounts, driveshafts and wheel bearings can produce overlapping symptoms.
Tell us whether the Grandland shudders at cruise, judders from a standstill, delays into Drive or behaves differently during Hybrid operation.
| What you notice | How drivers describe it | Possible areas to investigate |
|---|---|---|
| Judder pulling away | “It shakes as I move off or reverse.” | DCT clutch/actuator, conventional-auto clutch application, mounts or hybrid transition |
| Delay then engage | “I select Drive and it pauses before moving.” | Hydraulic pressure, clutch application, valve body or DCT control |
| RPM flare | “The revs rise without matching acceleration.” | Clutch slip, hydraulic pressure, CVT ratio control or internal wear |
| Harsh low-speed shift | “It jerks between the lower gears.” | Adaptation, valve body, DCT control or mounts |
| Whine / hum | “The noise changes with speed.” | Transmission/CVT bearings, differential, electric drive or wheel bearing |
| Warning / reduced power | “The gearbox or hybrid warning appears.” | Stored TCM/hybrid DTC, pressure/control fault or protection mode |
Fault codes help direct testing, but they should be interpreted with the exact transmission type, live data and the vehicle's symptoms.
| Fault code | What it broadly relates to | What may need checking |
|---|---|---|
| P0700 | Transmission control system warning request | Read the Vauxhall transmission/hybrid control modules for the underlying DTCs |
| P0715 | Input / turbine speed sensor circuit | Speed-sensor signal, wiring and transmission control data |
| P0730 | Incorrect gear ratio | Clutch application, CVT ratio control, hydraulic pressure or internal wear |
| P0741 | Torque-converter clutch performance where applicable | Converter lock-up, valve body, pressure and fluid condition on conventional automatic versions |
| P17xx family | Manufacturer-specific transmission / clutch-control faults | Vauxhall/Stellantis-specific TCM, DCT clutch/actuator or hybrid-transmission data |
Conventional-auto pressure/converter data and e-DCT clutch/hybrid data should be read according to the exact Grandland powertrain.
Repair cost depends on the exact gearbox family and whether the problem is a control/component fault or significant internal damage.
| Vauxhall Grandland gearbox work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan and road test | From £30 | 8-speed, PHEV, Hybrid DCT or Electric complexity |
| Valve-body / converter repair | Approx. £900 - £1,800 | Conventional/electrified 8-speed condition |
| Hybrid DCT clutch / actuator repair | Approx. £900 - £1,800 | Current e-DCT and hybrid integration |
| Full conventional automatic / DCT gearbox reconditioning | Approx. £2k - £4.5k+ | Transmission family and internal damage |
| PHEV / Electric integrated drive work | Diagnosis required | Electrified powertrain involvement |
We identify Grandland generation, engine and exact conventional automatic, PHEV, Hybrid e-DCT or Electric drive system.
Vauxhall-compatible diagnostics are used to read TCM/hybrid faults, converter, pressure, clutch and adaptation data.
Valve body, converter, DCT clutch/actuator or electrified-drive operation is tested against the symptom.
We recommend the repair indicated by the diagnosis and confirm the price before work begins.
Tell us the year, engine and exactly what the vehicle is doing so we can narrow down the correct transmission and repair route.
Service4Service Midlands provides Vauxhall Grandland gearbox diagnosis and repair for drivers across Birmingham, Coventry, Wolverhampton, Walsall, Solihull, Leicester, Derby, Nottingham, Stoke-on-Trent, Northampton and surrounding East and West Midlands areas.
Whether your Grandland is shuddering near Birmingham, delaying into Drive in Coventry or showing a Hybrid gearbox warning near Leicester, generation and powertrain identification comes first.

First-generation Grandland models used conventional automatic gearboxes including eight-speed applications, while the current Grandland Hybrid uses an electrified six-speed dual-clutch transmission.
Vauxhall specifies a six-speed dual-clutch automatic transmission for the current 48V Grandland Hybrid.
The earlier Grandland X Hybrid4 uses an electrified eight-speed automatic on the front powertrain.
Possible causes include converter lock-up, valve-body control, DCT clutch engagement, mounts or hybrid/driveline behaviour depending on the version.
A full conventional automatic / DCT gearbox reconditioning job is broadly around £2k–£4.5k+ as a guide, depending on transmission family and damage.
No. Grandland Electric uses an electric drive and reduction gear rather than a conventional multi-speed automatic.
Identify the exact transmission first, then repair the control, clutch, converter, CVT, DCT or internal gearbox fault testing actually confirms.
