ASTON MARTIN RAPIDE S 8-SPEED TRANSMISSION FD33-70041-AB
part number FD33-70041-AB identifies the 8-speed Touchtronic III Automatic Transmission (Transaxle) for the Aston Martin Rapide S (primarily 2015–2018 models).
This gearbox was the single most significant mechanical upgrade in the Rapide’s history, replacing the older 6-speed unit and transforming the car’s performance and efficiency.
1. Technical Specifications
-
Manufacturer: ZF Friedrichshafen (ZF 8HP70).
Type: 8-speed torque-converter automatic, mounted as a rear transaxle
-
Weight: 3% lighter than the previous 6-speed unit, despite having two additional gears.
-
Shift Speed: Capable of gear changes in just 130 milliseconds.
-
Layout: Connected to the engine via a revised magnesium-alloy torque tube and a carbon fiber propeller shaft.
2. Performance Impact
The switch to the 8-speed Touchtronic III (FD33 series) provided dramatic improvements over the earlier Rapide models:
-
Top Speed: Increased to 203 mph (327 km/h) due to the taller 8th gear.
-
Acceleration: 0–60 mph dropped from 4.7 seconds to 4.2 seconds.
-
Efficiency: Reduced CO2 emissions by roughly 10% and significantly improved highway fuel economy.
3. Compatibility & Identification
-
Direct Fit: Aston Martin Rapide S (2015–2020) and Vanquish S (where the same FD33-70041-AB unit is often shared).
-
The “FD33” Prefix: This prefix is essential. While the Rapide and Vanquish share the ZF 8HP70 architecture, the internal software and mounting points are specific to the “VH Generation 4” platform. It is not interchangeable with the 8-speed found in the newer DB11 or DBS (which use the “HY” or “KY” prefix parts).
4. Market Pricing & Sourcing (2026 Estimates)
As a high-performance transaxle, a brand-new unit is a major investment.
| Condition | Estimated Price | Note |
| New OEM (Dealer) | $12,500 – $14,800 | Often special order from the UK. |
| Used (Tested) | $5,200 – $7,100 | Highly sought after for “8-speed conversions” of older cars. |
| Remanufactured | $6,000 – $8,500 | Available from ZF specialists; includes a new Mechatronic unit. |
Maintenance Warning: The “Learning” Process
If you install a new or used FD33-70041-AB transmission, the vehicle’s TCM (Transmission Control Module) must be “flashed” with the car’s VIN and an Adaptation Drive must be performed.
-
The Symptom: Without this software handshake, the gearbox may experience “harsh engagement” into Drive or Reverse, and the paddle shifters may be disabled to protect the internal clutches.
