ZF 6HP Family
The ZF six-speed units used in earlier Sport models rely on conventional hydraulic control and torque-converter lock-up, making pressure, valve-body and converter condition key diagnostic areas.

The Range Rover Sport puts substantial torque through its automatic transmission, particularly when towing, climbing or accelerating hard. Earlier L320 models use ZF six-speed units, while later L320, L494 and current L461 versions move into the eight-speed 8HP family.
That progression changes the likely fault pattern. An older six-speed Sport may show converter or hydraulic wear differently from an L494 8HP70, and a current PHEV or SV adds another layer of powertrain integration.

Range Rover Sport Types, Generations and Gearboxes
Range Rover Sport transmission history moves from the ZF 6HP family in early L320 models to selected late-L320 and widespread L494 eight-speed applications, with current L461 vehicles continuing eight-speed automatic technology across MHEV, PHEV and high-output versions.

Range Rover Sport Gearbox Models Explained
ZF 8HP70 / 8HP Family
ZF 8HP/8HP70 on later models handles higher torque with more ratios and tighter clutch control. Smooth operation depends on stable pressure, converter behaviour and correct adaptation under load.
Later High-Torque 8HP
Current PHEV and SV derivatives add electrified or very high-output powertrains, so gearbox data may need to be considered alongside hybrid, engine and AWD systems.
Common Problems
Common Range Rover Sport Automatic Gearbox Issues
Sport owners commonly search for 'torque converter shudder', '8HP70 gearbox fault', 'bang into Drive', 'gearbox slipping under load' and 'judder on tight turns'. Towing, road speed and transfer-case behaviour are especially useful clues.
Torque-Converter Shudder
A vibration under light throttle at cruising speed can point towards converter lock-up, but propshaft, tyre and wheel faults can create a similar sensation.
Harsh Cold or Hot Shifts
A heavy thump into Drive or Reverse may involve hydraulic pressure, valve-body wear, clutch application, mounts or driveline lash.
Delayed Drive or Reverse
RPM flare on a climb or during strong acceleration suggests loss of clutch holding pressure and should be investigated before further internal wear develops.
Gearbox Warning / Limp Mode
Whine or hum under load can come from gearbox bearings, transfer case, differential, propshaft or wheel-bearing components.
Slipping or Flaring
Judder or binding during tight manoeuvres should be checked against the twin-speed transfer case and AWD driveline before the transmission is stripped.
Low-Speed Judder on Turns
A gearbox warning or stuck-gear condition may be caused by speed-sensor, mechatronic, ratio or internal faults that force the control system into protection mode.

Describe the Symptom
What Does a Range Rover Sport Gearbox Fault Sound or Feel Like?
Tell us whether the Sport fault appears while towing, accelerating uphill, cruising lightly or turning tightly at low speed. Load and steering condition can quickly separate converter, internal gearbox and transfer-case symptoms.
| What you notice | How drivers describe it | Possible areas to investigate |
|---|---|---|
| Shudder at cruising speed | “It vibrates under light throttle at 50–70 mph.” | Converter lock-up, valve body, fluid condition, propshaft or wheel/tyre issue |
| Bang into gear | “It engages Drive or Reverse with a thump.” | Hydraulic pressure, valve body, adaptation, mounts or internal clutch application |
| Flare between shifts | “The revs rise before the next gear takes.” | Clutch slip, pressure control, solenoid/valve body or internal wear |
| Whine / hum under load | “There is a drivetrain noise that changes with speed.” | Gearbox bearings, transfer case, differential, propshaft or wheel bearing |
| Judder on tight turns | “It feels like the vehicle is binding when manoeuvring.” | Twin-speed transfer case or AWD driveline before assuming gearbox failure |
| Stuck in one gear | “The warning came on and it stopped changing properly.” | TCM protection mode, speed-sensor plausibility, valve block or internal fault |
Important: Tight-turn judder can originate in the transfer case rather than the automatic gearbox.
Diagnostic Trouble Codes
Range Rover Sport Gearbox Fault Codes
Sport DTCs are interpreted with six-/eight-speed generation, speed-sensor plausibility, converter slip, hydraulic pressure and AWD data. High-load faults may only become obvious when the vehicle is tested under the conditions that trigger them.
| Fault code | What it broadly relates to | What may need checking |
|---|---|---|
| P0715-64 | Input/turbine shaft speed sensor A circuit — signal plausibility failure in JLR guidance | TCM adaptation/software, input-speed signal and mechatronic valve block |
| P0700-02 | Transmission control system warning / general signal failure | Underlying TCM DTCs and the transmission condition causing the warning |
| P0730 | Incorrect gear ratio | Clutch application, commanded/actual ratio, hydraulic pressure and internal wear |
| P0741 | Torque-converter clutch performance / stuck off | Converter lock-up, valve body, pressure regulation and fluid condition |
| P0729 | Gear 6 incorrect ratio on applicable diagnostic systems | Ratio monitoring, clutch application, pressure and internal mechanical condition |
L320 six-speed, L494 8HP and current L461 high-output/hybrid versions should be identified before repair decisions are made.
Repair Costs
How Much Does a Range Rover Sport Gearbox Repair Cost?
Range Rover Sport repair cost reflects transmission capacity and drivetrain complexity, from valve-body and converter work through six-speed or 8HP reconditioning to PHEV/SV-specific repairs.
| Range Rover Sport gearbox work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan, road test and initial assessment | From £30 | Depth of testing and whether transfer-case/driveline checks are required |
| Valve-body / solenoid related repair | Approx. £800 - £1,600 | 6HP/8HP variant, solenoids, hydraulic wear and coding |
| ZF six-speed full repair / reconditioning | Approx. £2k - £4k+ | Converter, clutches, valve body and internal hard-part condition |
| ZF 8HP / 8HP70 full repair / reconditioning | Approx. £3k - £4.5k+ | Powertrain torque, internal damage, valve body and converter condition |
| PHEV / SV high-output transmission work | Diagnosis required | Exact transmission derivative, hybrid/performance calibration and failed component |

How We Diagnose a Range Rover Sport Gearbox Fault
Identify the gearbox
We confirm Sport generation, engine, transmission family and PHEV/SV or towing specification.
Scan the transmission
JLR-compatible diagnostics are used to inspect ratio, pressure, converter, speed-sensor and relevant AWD data.
Test the fault area
The complaint is reproduced under an appropriate road load or low-speed steering condition where safe.
Quote the correct repair
We then quote the hydraulic, converter, internal or driveline repair supported by the diagnosis.

Common Search Questions
Range Rover Sport Gearbox Problems: Straight Answers
Why does my Range Rover Sport shudder at cruising speed?
Torque-converter lock-up is one possible cause, but propshaft, tyre, wheel and other driveline faults can create a similar vibration under light throttle.
Why does my Range Rover Sport bang into Drive or Reverse?
Hydraulic pressure delay, valve-body wear, clutch application, mounts and driveline lash can all contribute to a heavy engagement.
Can a Range Rover Sport 8HP valve body be repaired?
Yes. Many hydraulic and solenoid faults can be repaired or reconditioned once pressure and diagnostic testing confirms the valve body is responsible.
Why does my Range Rover Sport judder on tight turns?
Transfer-case or AWD driveline faults can cause binding during tight manoeuvres, so these should be checked before assuming the automatic gearbox itself has failed.
What is the difference between early Sport 6-speed and later 8-speed gearboxes?
Earlier L320 models use ZF 6HP-family automatics, while later Sport generations increasingly use the 8HP family with different hydraulic, clutch and control hardware.
How much does a Range Rover Sport gearbox repair cost?
The guide table lists six-speed reconditioning around £2k–£4k and ZF 8HP/8HP70 reconditioning around £3k–£4.5k; PHEV or SV work requires diagnosis.
