Performance gearbox & transmission upgrades

A performance gearbox upgrade involves changing suitable transmission or drivetrain components to meet a particular vehicle's requirements. Depending on the car, this may involve clutches, flywheels, differentials or other supporting hardware.

Gearbox tuning changes supported transmission-control software. Mechanical gearbox upgrades involve physical parts. The correct service depends on the gearbox and what you're trying to achieve.

Not automatically. The relevant gearbox and drivetrain requirements depend on the actual vehicle, engine torque, current condition and proposed setup.

Some Stage 2 setups may require gearbox or clutch considerations, but this isn't universal. The actual transmission and engine calibration should be reviewed.

An upgraded DSG clutch pack is a transmission-specific clutch assembly with different product specifications from the original arrangement. Available options depend on the actual gearbox.

Certain upgraded clutch products are designed for particular performance applications. Actual torque capability depends on the product specification, gearbox setup and operating conditions.

DQ250 and DQ381 are different Volkswagen Group DSG transmission families. Their internal components, applications and software requirements are not automatically interchangeable.

Aftermarket upgraded clutch products exist for selected DQ500 applications. Compatibility, availability and fitting requirements must be confirmed for the exact gearbox.

Selected DL501 applications have aftermarket transmission hardware options. The correct product and service depend on the actual gearbox specification.

No. Different DSG transmission families use different clutch arrangements. The exact gearbox must be identified before choosing parts.

No. They are different gearbox families with different clutch arrangements. A product for one should not be assumed suitable for the other.

ZF 8HP refers to a family of eight-speed automatic transmissions used in various vehicles. Different variants have different component and software requirements.

Some ZF 8HP applications have supporting transmission products and compatible software options. The exact gearbox code must be confirmed before selecting parts.

No. xHP is gearbox software for supported applications. It does not physically replace internal clutch components or strengthen mechanical parts.

Some supported gearbox calibrations offer different shift characteristics. Available features and actual results depend on the transmission and software.

Software may change supported transmission-control settings, but it does not automatically increase the physical capability of mechanical gearbox components.

A performance clutch is an aftermarket clutch assembly designed with particular materials or characteristics for a supported application. The appropriate product depends on the engine, gearbox and intended use.

A twin-plate clutch uses two friction discs within the clutch assembly. Products vary in design, operating characteristics and vehicle compatibility.

It may. Clutch engagement and pedal characteristics depend on the actual product, pressure plate and installation.

An aftermarket performance flywheel is a replacement flywheel designed for a particular engine and clutch arrangement. Different materials and designs can affect operating characteristics.

Suitable upgraded clutch products may be available for selected BMW manual models. The correct part depends on the exact engine, gearbox and existing clutch arrangement.

A limited-slip differential is designed to manage the distribution of drive torque between wheels according to its particular mechanical design.

A suitable differential may change traction characteristics in certain conditions, but the actual result depends on the vehicle, tyres, surface, setup and driving conditions.

STX Tuning can review enquiries for genuine suitable differential products, subject to actual vehicle fitment, current supply availability and installation acceptance.

Some transmissions have compatible supporting cooling components or more specialised upgrade options. The correct hardware depends on the gearbox and vehicle layout.

Not necessarily. Cooling requirements vary with the transmission, vehicle, operating conditions and proposed performance setup.

The appropriate maintenance and condition checks depend on the transmission and intended work. Tell STX Tuning about the gearbox's history and any current problems.

Slipping can have several causes, including mechanical or control-related problems. A gearbox remap is not a guaranteed repair for a slipping transmission.

STX Tuning can review suitable DSG clutch supply and fitting enquiries. Product compatibility, installation availability and the complete quotation must be confirmed.

Customer-supplied parts may be considered for fitting after checking the product, gearbox compatibility and proposed work.

Prices depend on the exact gearbox, manufacturer and product specification. Ask for a transmission-specific quotation.

Fitting costs depend on the vehicle, gearbox, component and work involved. Send us your registration and part details for a quotation.

Costs depend on the exact ZF transmission and hardware or software requested. A complete quotation requires the gearbox details.

You can enquire about compatible engine ECU and transmission TCU software together. Availability and pricing depend on the exact vehicle.

A hybrid turbo may change the engine's output and drivetrain demands. The gearbox, clutch and other supporting components should be considered for the actual build.

Selected Volkswagen Golf R generations have aftermarket gearbox and clutch options. The exact transmission must be identified before choosing products.

Selected Audi S3 and RS3 gearbox applications have performance hardware or software options. Compatibility varies by gearbox and generation.

A BMW M140i may have different transmission configurations. STX Tuning can review the relevant hardware and software enquiry once the actual gearbox is identified.

Yes. Suitable manual performance cars may have aftermarket clutch, flywheel, differential or other drivetrain hardware options.

Replacement or performance gearbox enquiries need to consider the original problem, exact vehicle and available products. The appropriate service must be confirmed individually.

Supply-only enquiries may be available for suitable genuine products. Pricing and availability must be confirmed.

STX Tuning is based in Slough, Berkshire, and welcomes suitable gearbox hardware and software enquiries from surrounding areas.

Timescales depend on the vehicle, components, fitting work and parts availability. A clutch replacement or major transmission project may require different arrangements from gearbox software.

Yes. You can request one quotation covering suitable transmission hardware, ECU software, gearbox tuning and other relevant performance upgrades.
