Automatic transmission 8HP-70X 330d xDrive BMW F30 F34 F35 F80 31TKM

For your inventory at Buy Mustang parts Ltd, the ZF 8HP70X is a high-demand transmission for the European and diesel performance markets. This specific unit, sourced from a 330d xDrive with only 31,000 km (31TKM), is a “Grade A+” mechanical asset.

1. Technical Specification & Fitment

The “X” suffix in 8HP70X denotes the xDrive (All-Wheel Drive) version. This transmission is engineered to handle the massive low-end torque of BMW’s 3.0L N57 straight-six diesel engine.

• Model: ZF 8HP70X (BMW Code: GA8HP70X)

• Torque Rating: 700 Nm (516 lb-ft).

• Application: Primarily for F30 (Sedan), F31 (Touring), and F34 (Gran Turismo) 330d/335d xDrive models.

• Cross-Compatibility: While it physically fits F80 (M3) chassis points, it is technically calibrated for the diesel torque curve. It is also commonly found in xDrive variants of the 4 Series (F32/F33/F36) and 5 Series (F10/F11).

2. Premium Inventory Inspection (31TKM)

At 31,000 km, this unit is barely broken in. To list it as a “Luxury Spare” for your website, verify the following:

1. Transfer Case Integration: As an “X” model, it mates directly to the ATC35L transfer case. Inspect the output splines for any signs of “fretting” or dry wear.

2. Mechatronic Condition: The internal TCM (Transmission Control Module) is highly reliable but sensitive to static. Ensure the electrical pins are protected during storage.

3. The “ZF Lifeguard 8” Check: Check the fluid color. At 31k km, it should still be a translucent green/honey color. If it’s dark, it may indicate heavy towing or hard launches (typical of 330d owners).
