Automatic transmission with clutch Maserati GranTurismo – 0755145

transmission identification you are referencing, 0755145, appears in several salvage and parts databases as a generic reference number for a GranTurismo “gearbox with clutch.”

Critical Warning: Transmission Type Verification

Before you proceed with this part, you must confirm which transmission the car actually has. The Maserati GranTurismo (M145) was built with two fundamentally different types of transmissions that are not interchangeable:

1. Automated Manual (MC-Shift / DuoSelect / Cambiocorsa):

   • Features: This is a robotized manual transmission that uses a clutch and flywheel.

   • Identification: Shifts can be jerky, especially at low speeds. It is found in the GranTurismo S (2008–2012) and the MC Stradale.

   • Part Compatibility: Part 0755145 (if described as having a “clutch”) is intended for these models.

2. Conventional Automatic (ZF 6HP26 / MC Auto Shift):

   • Features: This is a traditional torque-converter automatic. It does not have a clutch or a flywheel (it uses a flexplate).

      

   • Identification: Very smooth, fluid gear changes. This is the standard transmission for the vast majority of GranTurismo models, including the base GranTurismo, GranTurismo S Automatic, and GranTurismo Sport.

   • Part Compatibility: This part will NOT fit vehicles equipped with the ZF automatic transmission.

      

Inventory Checklist for “Buy Mustang parts Ltd”

To ensure you do not order or supply the wrong unit to your clients, follow this protocol:

• Request the VIN: Never rely on a generic part number like 0755145. The last 7 digits of the VIN will reveal the specific build and transmission type.

• Physical Inspection: If you have the unit in hand, check for a clutch housing or a flywheel at the bellhousing end. If you see a torque converter, it is a ZF automatic, and the “clutch” description in the listing is incorrect or refers to a different variant.

• Donor Vehicle History: Ask the supplier for the VIN of the car the transmission was removed from. Running that VIN through a decoder will explicitly state “Automated Manual” or “ZF Automatic.”

Recommendation: If you are stocking this unit, clearly label it on your website as “Automated Manual (MC-Shift) – Requires Clutch/Flywheel” versus “ZF Automatic – Torque Converter Equipped.” Misidentifying this is a high-cost error that will lead to returns and damage your reputation for accuracy.
