## Cars with Pump-Dependent Manual Transmissions
A pump-dependent manual transmission (PDMT) is a type of manual transmission that uses a hydraulic pump to assist in the shifting of gears. This type of transmission is often used in heavy-duty vehicles, such as trucks and buses, as it can provide the driver with more precise control over the vehicle’s gear changes.
There are a number of different makes and models of cars that have been equipped with PDMTs over the years. Some of the most notable examples include:
– Alfa Romeo 155 Q4
– Audi Quattro
– BMW M5 (E34)
– Ferrari F40
– Lamborghini Countach
– Mercedes-Benz 190E 2.5-16
– Mitsubishi Lancer Evolution
– Nissan Skyline GT-R
– Porsche 911 Turbo
– Subaru Impreza WRX STI
– Toyota Supra
– Volkswagen Golf R32
### Advantages of PDMTs
There are a number of advantages to using a PDMT over a traditional manual transmission. These advantages include:
– Increased precision: PDMTs provide the driver with more precise control over the vehicle’s gear changes. This is especially beneficial in racing applications, where even a slight advantage in gear shifting can make a big difference.
– Reduced effort: PDMTs can help to reduce the effort required to shift gears. This can be a significant benefit for drivers who have difficulty with traditional manual transmissions.
– Smoother shifting: PDMTs can provide smoother shifting than traditional manual transmissions. This is because the hydraulic pump helps to absorb some of the shock of the gear change.
– Increased durability: PDMTs are generally more durable than traditional manual transmissions. This is because the hydraulic pump helps to reduce the wear and tear on the transmission’s components.
### Disadvantages of PDMTs
There are also some disadvantages to using a PDMT over a traditional manual transmission. These disadvantages include:
– Increased cost: PDMTs are typically more expensive than traditional manual transmissions. This is because they require more complex components.
– Increased weight: PDMTs are also typically heavier than traditional manual transmissions. This can be a disadvantage in racing applications, where every pound counts.
– Reduced efficiency: PDMTs can be less efficient than traditional manual transmissions. This is because the hydraulic pump consumes some of the engine’s power.
– Increased complexity: PDMTs are more complex than traditional manual transmissions. This can make them more difficult to maintain and repair.
### Conclusion
PDMTs offer a number of advantages over traditional manual transmissions. However, they also have some disadvantages. Ultimately, the best type of transmission for a particular application will depend on the specific needs of the driver and the vehicle.
