Aston Martin VANTAGE Automatic Transmission 7 ED237002 BE

part number ED23-7002-BE (often seen in variations like -BC) identifies the 7-speed Sportshift III Automated Manual Transmission for the Aston Martin V12 Vantage S (2013–2018).

While often referred to as an “automatic” because it lacks a clutch pedal, this is technically an automated manual transaxle manufactured by Graziano. It is a major evolution over the 6-speed Sportshift I and 7-speed Sportshift II found in earlier V8 models.

1. Technical Specifications

• Type: 7-speed single-clutch automated manual (Transaxle).

• Manufacturer: Graziano Trasmissioni.

• Shifting: Controlled via steering column paddles or “Auto” mode buttons on the center console.

• Performance: Capable of gear changes in under 50 milliseconds, significantly faster than the previous 6-speed units.

• Weight: Approximately 25 kg (55 lbs) lighter than the standard manual 6-speed gearbox, helping the V12 Vantage S achieve its front-mid engine balance.

2. Key Features of Sportshift III

• Bosch Management: The “ED23” series utilizes Bosch engine and transmission management, which provides much smoother low-speed “creep” and more aggressive rev-matching than earlier units.

• Integrated LSD: Features a high-performance Limited Slip Differential built into the rear of the casing.

• Sport Mode: When engaged, it sharpens shift times and increases the exhaust note on downshifts.

3. Common Maintenance & Issues

1. Clutch Wear: Because it is a single-clutch system, the car physically “slips” the clutch in traffic just like a human would. Reverse gear is quite “tall,” so reversing up hills can cause premature wear.

2. The “Clutch Learn”: To keep the transmission smooth, it is recommended to let the car idle in Neutral for 15 seconds after a cold start. This allows the TCU (Transmission Control Unit) to calibrate the clutch bite point.

    

3. Oil Leaks: Inspect the cooling lines and the Hydraulic Actuator (part of the 7-speed system) for leaks. The actuator uses specialized Pentosin fluid and is a high-pressure component.

4. Market Pricing (2026 Estimates)

The Sportshift III is a specialized unit and significantly more expensive to replace than the later ZF 8-speed automatics.

Important Note: “Sportshift” vs. “Automatic”

If you are buying this for a 2019+ Vantage (4.0L V8), this part will not fit. The newer Vantage uses a ZF 8-speed torque-converter automatic (Part No. JY53-70041-AB). The ED23 unit is strictly for the earlier V12 Vantage “S” models.
