ZF 8HP90 Gearbox Australia: Buyer, Swap & Fitment Guide

Looking for a ZF 8HP90 in Australia? The 8HP90 is the heaviest-duty member of ZF's eight-speed automatic family, used behind the most powerful factory applications and increasingly common in high-power swaps. This guide covers what the 8HP90 is used in, how it compares with the 8HP95 and 8HP76, what to confirm before you buy, and the supporting parts that make a conversion work.

If you already know what you need, jump to the ZF 8HP gearboxes currently listed, or send your build details through Find the Right 8HP Parts and we will confirm what fits.

What the 8HP90 is used in

• Dodge and SRT applications including Challenger and Charger Hellcat variants.
• BMW high-torque platforms such as the N73 and N74 V12 cars.
• Custom and conversion builds that want the strongest factory 8HP hardware available.
• Heavy-duty swaps where an 8HP70, 8HP75 or 8HP76 does not have the headroom the build needs.

The 8HP90 is a big, heavy gearbox. It makes sense when the torque target and duty cycle genuinely justify it, and less sense when a newer-generation 8HP76 would do the job with lighter weight and simpler packaging.

8HP90 vs 8HP95 vs 8HP76

The 8HP95 is the closely related variant used in the Jeep Grand Cherokee Trackhawk, with a different configuration and output arrangement. The 8HP76 is the newer-generation box we normally recommend for 1000HP and 1500HP builds, because it is lighter, better supported for standalone control and easier to package. Compare the options in 8HP51 vs 8HP76 vs 8HP90 and the full Which 8HP should you buy? guide, and see the dedicated 8HP95 page if the Trackhawk unit is what you are chasing.

What to confirm before buying an 8HP90

• Exact gearbox tag and model code, and whether the unit is 8HP90 or 8HP95.
• RWD or AWD layout, output flange and transfer case arrangement.
• Bellhousing and adapter requirements for your engine.
• Mechatronics generation and wiring compatibility.
• Controller choice: CanTCU, TurboLamik or ECU integration, and whether your target unit is supported.
• Physical size, weight, mounts and tunnel clearance.
• Mileage, condition, and whether the unit has been opened or rebuilt.

Because the 8HP90 and 8HP95 share so much hardware, confirm the exact unit and driveline configuration rather than treating the family name as a fitment guarantee.

Controller support

Standalone control is what makes an 8HP90 conversion practical outside a factory engine bay. TurboLamik is the flexible standalone used across a wide range of 8HP conversions, and CanTCU is the strongest BMW-focused option where the build stays BMW-based. Match the exact transmission and generation to the controller before you commit. Start with the 8HP controller guide or browse TCU controllers and harnesses.

Build the 8HP90 as one package

The 8HP90 is rarely a bolt-in. Plan the mounts, cooling, driveline and control together, and price the whole system rather than the gearbox line alone.

• Mounts: dedicated 8HP90 rear mounts are available for BMW N73/N74 and Dodge applications.
• Oil pan and service: see the 8HP90 oil pan and the 8HP90 oil pan with pressure/temp sensor, plus the billet deep transmission pan for 8HP90/95.
• Driveline and AWD to RWD: compare output flanges and driveline parts and AWD / RWD conversion parts, including the Trackhawk AWD-to-RWD conversion and the LT230 transfer case adapter.
• Cooling: review cooling and filtration and the 8HP service guide.
• Engine interface: for Hemi conversions see the Dodge Hemi to ZF 8HP adapter and compare engine adapter kits.
• Shifter and controls: compare shifter and control options.

Frequently asked questions

Is the 8HP90 the strongest ZF 8HP gearbox?

The 8HP90 and its close relative the 8HP95 sit at the top of the factory 8HP range for torque capacity. For most high-power swaps, though, a newer-generation 8HP76 is the box we recommend, because it is lighter, better supported for standalone control and easier to package.

Can you supply an 8HP90 gearbox?

Availability varies. Send your build details and we will confirm what is available or sourceable, along with the supporting parts.

Can you confirm fitment using my VIN or photos?

Yes. Send your VIN, the transmission tag and clear photos through Find the Right 8HP Parts and we will help narrow the correct unit and supporting parts.

Do you ship 8HP90 parts Australia-wide?

Yes. Freight cost and timing depend on the item and your location, and are confirmed before dispatch. See the shipping and delivery notes or ask when you order.
