The RX7, a legendary sports car, is renowned for its unique rotary engine. But its performance hinges on another crucial component: the Rx7 Transmission. This intricate system transfers power from the engine to the wheels, directly impacting your driving experience. Whether you’re a seasoned RX7 enthusiast or a curious gearhead, join us as we explore the intricacies of this iconic car’s transmission.
Decoding the RX7 Transmission
Unlike traditional piston engines, the rotary engine’s high-revving nature demands a specifically designed transmission. The RX7 utilizes a manual transmission known for its precise shifting and durability. Let’s break down the key aspects:
- Gear Ratios: The RX7 transmission features closely spaced gear ratios optimized for the rotary engine’s powerband. This allows for rapid acceleration and exhilarating performance on both the street and track.
- Shift Mechanism: Known for its short throw and precise engagement, the RX7’s shifter offers a connected and satisfying driving experience.
- Clutch System: A robust clutch system is essential to handle the rotary engine’s power delivery. The RX7 typically employs a hydraulic clutch for smooth and consistent engagement.

Common RX7 Transmission Issues
While the RX7 transmission is generally reliable, certain issues can arise over time or due to aggressive driving:
- Synchro Wear: The synchros, responsible for smooth gear changes, can wear down, leading to grinding or difficulty shifting.
- Clutch Master/Slave Cylinder Failure: Leaks or failures in the clutch hydraulic system can result in a loss of clutch pressure, making it difficult or impossible to shift gears.
- Input/Output Shaft Bearings: Worn bearings can create noise and vibration, particularly during acceleration or deceleration.
Maintaining Your RX7 Transmission
Proper maintenance is key to ensuring the longevity and performance of your RX7 transmission. Here are some essential tips:
- Regular Fluid Changes: Use high-quality transmission fluid specifically designed for the RX7 and follow the manufacturer’s recommended service intervals.
- Inspect for Leaks: Regularly check for any signs of fluid leaks around the transmission and address them promptly.
- Avoid Abusive Shifting: Harsh or missed shifts can put unnecessary stress on the transmission components, leading to premature wear.
Upgrading Your RX7 Transmission
For those seeking enhanced performance, various aftermarket options are available to upgrade the RX7 transmission:
- Short Shifters: Reduce throw distance for quicker, more precise shifts.
- Lightweight Flywheels: Decrease rotational mass for improved engine response and acceleration.
- Performance Clutch Kits: Handle increased power and torque from engine modifications.
