ZF 8HP Gearboxes

Shop ZF 8HP gearboxes for swaps, replacement planning and performance builds. Use the transmission code, donor details and complete conversion plan to narrow the right gearbox before ordering.

How to choose a ZF 8HP gearbox

1. Confirm the exact transmission code. “8HP” is a family, not one interchangeable gearbox. Record the full code and donor vehicle details.
2. Match the engine interface. Check the bellhousing, adapter and flexplate path against your engine and chassis. Browse engine adapter kits alongside the gearbox.
3. Plan the electronics. Confirm that the chosen controller and harness supports the exact transmission, ECU and vehicle setup.
4. Plan the output and driveline. Check RWD or AWD requirements, output flange, tailshaft, mount and shifter before checkout.
5. Do not forget cooling and service parts. Build the cooling and filtration plan around the vehicle, intended use and available packaging.

Buying a gearbox for an 8HP swap

Start with the engine, chassis, transmission code, ECU, RWD or AWD layout and intended use. Then compare the gearbox listing with the adapter, controller, driveline and cooling requirements as one system. A cheap gearbox becomes expensive quickly when the rest of the conversion does not match.

Use the 8HP Swap Guides to map the package, or browse the 8HP Parts Catalog for the supporting categories.
