What We Do

Manual Transmission Expertise

Many Porsche owners want the engagement of a manual gearbox—whether converting from Tiptronic or another automatic, upgrading to a stronger transmission, or pairing a manual with an LS conversion. CPE designs and fabricates the adapters, mounts, and hydraulic solutions needed for a reliable install.

We handle cable and hydraulic clutch setups, shifter positioning, and driveline alignment so your Porsche shifts cleanly on the street or track. Full in-house labor is available; we also supply components for experienced builders and for projects already on a Porsche LS swap kit path (clutch kits, flywheels, and related driveline pieces).

Who this is for

Tiptronic and other automatics. Owners who want pedal and clutch engagement without living with the factory automatic box are a primary audience for CPE manual conversion work—whether the car keeps factory power for now or is headed for an LS later.

LS conversion path. For LS programs, Chavis Performance & Engineering engineers around a manual transaxle. As stated in our FAQ: Tiptronic and PDK are not supported for the LS conversion as-is. If you have an automatic car, converting to a manual first (or as part of the overall project plan) is the route we use.

Manual-to-manual upgrades. Some projects need a stronger or different manual gearbox, revised clutch packaging, or cleaner shifter geometry when power or use-case outgrows the original setup. We scope those as driveline projects, not one-size bolt-ons.

Process overview

  1. Intake & assessment. Share chassis (996, 997, 986, 987, 911, etc.), current transmission, odometer-level goals, and whether this is a standalone manual conversion or part of an LS build. Photos and transmission type save back-and-forth— contact CPE with that package.
  2. Driveline plan. We define gearbox path, clutch/hydraulics strategy, mounts and adapters, and any packaging constraints for your car. When the project is also an LS conversion, plan aligns with transmission options for Porsche LS swaps and with in-house LS3 / LS7 packaging norms.
  3. Fabrication & install. Adapters, mounts, hydraulic or cable clutch solutions, and shifter positioning get built and installed to support clean shifts—not merely “fits the hole.” Parts that ship DIY use the same engineering mindset behind shop installs.
  4. Validation. For in-house work, the car leaves only after inspection and a drive check appropriate to the job scope. We will be straight about power limits and transmission health— many LS builds sit comfortably around 500 wheel horsepower and 500 lb-ft with a healthy driveline; much higher figures depend on driving style and gearbox condition (see FAQ).

Automatic (Tiptronic / PDK) and LS projects

We do not engineer CPE LS conversion packages to keep Tiptronic or PDK in place. That is a hard product boundary so owners plan the right sequence: get the car on a manual transmission path that our mounting, clutch, and integration packages are designed around.

PDK and Tiptronic differ in control systems and service reality. We do not publish one-size PDK “tear-down tutorials” on this page—those cars need a real conversation about parts sourcing, donor manual gearboxes, electronics scope, and budget before any hardware is ordered. Use the FAQ transmission answer and then call or email the shop with your VIN-level setup.

Owners already on a factory manual who only need clutch, flywheel, or gearbox-side upgrades during an LS project should start with Clutch Kits & Flywheels in the store and the transmission planning guide.

Pricing and scope

Manual conversion pricing is project-specific (chassis, donor gearbox availability, hydraulic vs cable decisions, and how much fab is already complete). We do not publish a single flat retail number that would mislead half of the cars that land on this page.

When a manual conversion is bundled into a full in-house LS conversion, that larger program has published bands in the FAQ— turnkey in-house LS work typically starts around $45,000 for RWD or AWD cars, with extras (aero, suspension, paint, heavy customization) adding from there. DIY LS parts packages for common LSx-to-996/997 paths sit in a different band (~$12,000 shipped for a complete conversion kit style package—options and freight change the total). Manual-only work is quoted separately when it is not part of those kits.

For budget planning on the engine swap itself, read the Porsche LS swap cost guide.

Next steps

1. Confirm chassis and transmission type. 2. Decide standalone manual conversion vs combined LS project. 3. Contact CPE with photos and goals—or browse conversion parts if you already know the subsystems you need.
