ZF 8HP45 / 8-Speed
Used widely across four-cylinder XE petrol and diesel applications. Valve-body wear, pressure control, converter lock-up and internal clutch condition are key diagnostic areas.

Specialist diagnosis, repair and reconditioning for Jaguar XE automatic gearboxes, centred on the ZF eight-speed automatic used across petrol, diesel, rear-wheel-drive and all-wheel-drive XE applications.
If your XE delays into Drive, shudders at cruising speed, bangs through gears, slips or shows a transmission warning, we diagnose the ZF automatic and surrounding driveline before replacing parts.
The XE was launched with ZF eight-speed automatic technology. Jaguar documented the 8HP45 on four-cylinder and diesel applications and 8HP70 on higher-output V6 versions, with later XE powertrains also matched exclusively to eight-speed automatics.
| XE generation / type | Typical UK versions | Automatic gearbox | What owners often search for |
|---|---|---|---|
| XE X760, 2015–2018 | 2.0 diesel/petrol, 3.0 V6, RWD/AWD | ZF 8HP45 on many four-cylinder applications; 8HP70 on higher-output V6 applications | XE 8HP45 fault, gearbox shudder, delayed Drive |
| XE facelift, 2019–2024 | Ingenium petrol/diesel, MHEV, RWD/AWD | Jaguar 8-speed automatic across the range | XE gearbox warning, harsh shift, torque-converter shudder |
Used widely across four-cylinder XE petrol and diesel applications. Valve-body wear, pressure control, converter lock-up and internal clutch condition are key diagnostic areas.
Used on higher-torque V6 applications. It shares the eight-speed architecture but has greater torque capacity and different internal component requirements.
AWD XE models add transfer and front-driveline components, so vibration or clunks should be separated from a genuine transmission fault.
XE ZF eight-speed faults can feel similar whether the cause is valve-body control, torque-converter lock-up, internal clutch wear or the AWD driveline.
A pause before the car engages can involve hydraulic pressure, clutch application, valve-body operation, converter fill or internal seal wear.
Abrupt changes can involve adaptation values, pressure-control solenoids, valve-body wear, mounts or internal clutch damage.
A vibration at steady speed can involve torque-converter lock-up on conventional automatics, but driveline and wheel/tyre faults should also be ruled out.
If engine speed rises without matching acceleration, internal clutch slip or hydraulic pressure loss should be investigated quickly.
A gearbox warning or restricted gears should be scanned with Jaguar-compatible diagnostics before parts are replaced.
Noise can come from the transmission, but differential, propshaft, driveshaft, mount and wheel-bearing faults can feel gearbox-related.
Tell us whether the XE shudders at steady speed, delays before Drive or bangs on a specific upshift/downshift; those patterns help separate converter, valve-body and internal faults.
| What you notice | How drivers describe it | Possible areas to investigate |
|---|---|---|
| Delay then thump | “I select Drive and it pauses before engaging.” | Hydraulic pressure, clutch application, valve body, converter fill or seals |
| Shudder at steady speed | “It vibrates gently when cruising.” | Torque-converter lock-up, valve body, driveline or wheel/tyre issue |
| RPM flare | “The revs rise before the next gear catches.” | Internal clutch slip, pressure loss, valve body or worn sealing elements |
| Harsh downshift | “It bangs as I slow down.” | Adaptation, pressure-control solenoid, valve body, mounts or internal wear |
| Whine or hum | “The noise changes with road speed.” | Transmission bearings, differential, propshaft, driveshaft or wheel bearing |
| Warning / limited gears | “The gearbox warning appears and it stops shifting normally.” | Stored TCM DTC, pressure/control fault, sensor data or protection mode |
XE fault codes should be interpreted with Jaguar/ZF live data, adaptation values and pressure behaviour. Generic codes alone are not a diagnosis.
| Fault code | What it broadly relates to | What may need checking |
|---|---|---|
| P0700 | Transmission control system warning request | Read the Jaguar transmission control module for the underlying gearbox-specific DTCs |
| P0715 | Input / turbine speed sensor circuit | Speed-sensor signal, wiring, control data and internal transmission operation |
| P0730 | Incorrect gear ratio | Commanded versus actual ratio, clutch application, hydraulic pressure and internal wear |
| P0741 | Torque-converter clutch performance on applicable conventional automatics | Converter lock-up, valve body, hydraulic pressure and fluid condition |
| P0796 | Pressure-control solenoid performance / stuck condition | Valve body, solenoid operation, pressure regulation and hydraulic integrity |
ZF 8HP diagnosis should include transmission temperature, converter slip, clutch-fill/adaptation data and Jaguar-specific faults where available.
XE repair cost depends on the exact ZF 8HP variant and whether the fault is valve-body, torque-converter or internal.
| Jaguar XE gearbox work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan and road test | From £30 | RWD/AWD and fault complexity |
| Valve-body / solenoid repair | Approx. £800 - £1,600 | Valve-body wear and pressure-control fault |
| Torque-converter related repair | Approx. £900 - £1,800+ | Converter lock-up condition and removal labour |
| Full conventional automatic / gearbox reconditioning | Approx. £2k - £4.5k+ | Transmission family and internal damage |
| AWD / high-output transmission work | Diagnosis required | Exact ZF unit and driveline involvement |
We identify XE engine, year, RWD/AWD status and exact ZF eight-speed variant.
Jaguar-compatible diagnostics are used to read TCM faults, converter slip, adaptations and pressure-related data.
Valve body, converter, internal clutches and AWD driveline are tested against the reported symptom.
We recommend the repair indicated by the diagnosis and confirm the price before work begins.
Tell us the XE year, engine and whether it is AWD, plus exactly when the gearbox symptom appears.
Service4Service Midlands provides Jaguar XE 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 XE is shuddering on the M6 near Birmingham, delaying into Drive in Coventry or shifting harshly around Leicester, the ZF automatic and driveline should be diagnosed together.

Jaguar XE models use an eight-speed automatic. Jaguar technical data identifies ZF 8HP45 and 8HP70 variants on different early applications, with later XE models also using eight-speed automatics.
Torque-converter lock-up is one possibility, but propshaft, wheel/tyre and differential issues can create similar vibration.
Many valve-body, solenoid and hydraulic-control faults can be repaired or reconditioned once diagnosis confirms the failure.
Possible areas include hydraulic pressure, valve-body operation, converter fill, clutch application and internal sealing wear.
A full conventional automatic / gearbox reconditioning job is broadly around £2k–£4.5k+ as a guide, depending on the exact transmission and internal damage.
If it is slipping, losing gears or banging heavily, avoid unnecessary driving and arrange diagnosis.
