ZF 8HP76X
ZF 8HP76X (GA8HP76X): 8-speed automatic transmission. The named G30 and F90 factory ratio sets are shown separately. G30's 5.500 first gear and M5's 5.000 first gear cannot be interchanged.
The named G30 and F90 factory ratio sets are shown separately. G30's 5.500 first gear and M5's 5.000 first gear cannot be interchanged.
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
- GA8HP76X
The reviewed factory sheets give no separate transmission torque limit. Engine and hybrid system torque are not such limits.
Gear ratios
F90 ratios are factory references for the named models. The sheets do not name 8HP76X; the M5 code mapping and generation boundary need further verification. 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.

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.
ZF fluids and oil change kitsZF identification
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.
