ZF 8HP75X
ZF 8HP75X (GA8HP75X): 8-speed automatic transmission. G30 530d xDrive ratios are verified against a factory source. Conflicting sources leave the early F90 M5 reverse ratio unresolved.
G30 530d xDrive ratios are verified against a factory source. Conflicting sources leave the early F90 M5 reverse ratio unresolved.
This database is the result of research carried out by Six-In-Line Kft. in its spare time.
Technical data
- Transmission version
- 8 -speed automatic
- Reference torque limit
- Not separately verified
- Manufacturer
- ZF
- BMW code reference
- GA8HP75X
The reviewed factory sheets give no separate transmission torque limit. Engine and hybrid system torque are not such limits.
Gear ratios
The M5 sheet dated 08/2017 gives 4.172 for reverse; BMW training material gives 3.478. The early M5 reverse value is left blank; this does not establish a transmission generation change. View sources

Reverse is consistently shown with a negative sign; BMW data sheets give the magnitude of the ratio. Versions are separate data rows; the table does not individually assign the correct version to vehicles.
Fluid data

- F90 M5 · 08/2017: ZF LifeguardFluid 8
ZF 50130 and TE-ML 11 list LifeguardFluid 8 for the named 8HP versions. Confirm the specification using the full transmission ID and BMW/OE part number; no fill quantity is inferred.

Ratios come from the factory sheet for the named BMW model. The ZF/BMW code mapping comes from the research dataset and must be checked on the actual vehicle.
Check the full type, HIS/IEP/X suffixes, ZF assembly number and BMW/OE part number together. A shared transmission family does not establish interchangeability.
The M5 8HP75X/8HP76X changeover date is unconfirmed. Training designations GM8HP75Z / M8HP75 are kept separate; identical ratios do not establish identical codes.
Record the full marking on the transmission housing. ZF’s guide shows both plate and stamped identification variants.
- Type designation
- The exact type shown on the plate, including every suffix.
- Full ZF catalogue number
- Catalog Number / bill-of-materials number. The full number is required to identify parts.
- Serial number
- Serial Number. Identifies the individual unit; not the same as the transmission family code.
- BMW / OE markings
- Manufacturer part numbers and other codes on the plate. Available fields vary by version.
The prefix is not a complete order number and does not by itself confirm compatibility of the specific version.
Label colour, casting marks and a suffix alone are insufficient for full identification. We do not use Excel’s general “X and Z = all-wheel drive” statement to identify the drivetrain.
