ZF 8HP45 Gearbox Australia: Buyer & Swap Guide
Looking for an 8HP45 gearbox or planning an 8HP45 swap in Australia? Start with the transmission identification tag, donor layout and complete conversion plan. The badge alone is not enough to confirm fitment.
Buyer shortcut: identify the exact unit first, then match the gearbox, adapter or flexplate, controller and harness, driveline layout, shifter and cooling parts. Buying the “right-looking” transmission before checking those interfaces is an expensive way to build a garage ornament.
What is the ZF 8HP45?
The 8HP45 is one member of the ZF 8HP eight-speed automatic transmission family. Different donor applications can use different bellhousing, output, AWD/RWD, electronic and supporting-part arrangements, so a listing title or exterior photo is not a fitment guarantee.
Before buying an 8HP45 gearbox
- Read the identification tag: record the complete transmission code and clear photos of the tag and connection points.
- Confirm the donor layout: establish whether the unit is RWD or AWD/xDrive and document the output arrangement.
- Check condition evidence: ask for the stated kilometres, donor details and any available service or operating history.
- Map the engine interface: confirm the required bellhousing, adapter, flexplate, converter and starter strategy for your exact engine and chassis.
- Choose controls early: verify the controller, harness, shifter and vehicle-integration plan before ordering hardware.
- Plan the complete driveline: account for mounts, output flange, tailshaft, clearance, cooling and intended use.
Compare current ZF 8HP gearbox options. Availability, condition and included components belong to the individual product listing, not this guide.

Use the 8HP Parts Catalog to browse the wider conversion system. Product descriptions define what is included; do not assume a gearbox, adapter or controller listing includes the rest of the swap.
Should you buy an 8HP45 or another ZF 8HP?
Choose from verified compatibility, condition, packaging and the parts path for the whole build, not model-number bragging rights. If more than one transmission can suit the project, compare the available units and supporting hardware before committing.
