The 2001 Acura CL Type S represents a pinnacle of late-1990s sporty sedan engineering, blending refined luxury with accessible performance. At the heart of its engaging dynamics lies a sophisticated transmission system, meticulously engineered to deliver power to the pavement with precision and durability. Understanding the specifications, functionality, and common maintenance requirements of this specific powertrain is essential for current owners, enthusiasts, and potential buyers of this refined coupe.
2001 Acura CL Type S Powertrain Overview
Unlike its standard V6 counterpart, the Type S variant was equipped with a high-revving 2.3-liter inline-five engine, producing 260 horsepower and 270 lb-ft of torque. This powerplant, shared with the contemporary Honda Integra Type R (DC5), demanded a transmission capable of handling the extra torque and aggressive camshaft profiles. The specific unit mated to the 2001 Type S was a close-ratio 5-speed manual transmission, designed for optimal gear engagement and engine speed retention during spirited driving.
Close-Ratio Gear Design and Performance Benefits
The term "close-ratio" is central to the Type S driving experience. This configuration means the difference between adjacent gears is minimal, effectively reducing the engine's rpm drop between shifts. The result is an almost seamless acceleration curve, allowing the driver to keep the engine within its optimal power band. This design choice prioritizes responsiveness and track-focused performance over relaxed highway cruising efficiency, making each gear change feel immediate and purposeful.
Manual Transmission Specifications
Automatic Transmission Option and Controversy
While the manual was the performance flagship, a 4-speed automatic transmission was available for the 2001 CL Type S, primarily targeting buyers who desired the model's luxury and safety features without the commitment of a manual. This automatic unit, often identified as the automatic transmission option, was a source of debate among enthusiasts. While technologically advanced for its time, its gear ratios and torque converter setup were not as favorably aligned with the Type S's aggressive character, often resulting in delayed shifts and a less connected driving feel compared to its manual counterpart.
Common Issues and Maintenance
Owning a 2001 Acura CL Type S with its transmission requires attention to specific maintenance intervals to ensure longevity. For the manual transmission, the hydraulic clutch system is robust but the clutch plates themselves are wear items. Symptoms such as a slipping clutch or a soft pedal feel indicate the need for replacement. Gear oil is another critical component; the transmission requires 75W-90 GL-4 gear oil, and regular changes (every 30,000 to 50,000 miles) are vital to prevent wear on the close-ratio gears and bearings.
Clutch Replacement and Fluid Service
Use high-quality 75W-90 GL-4 gear oil for the transmission and 10W-30 or 10W-40 for the engine.
Inspect clutch fluid level annually; a drop may indicate a leak in the master or slave cylinder.
When replacing the clutch, consider upgrading to a performance clutch kit for improved durability and engagement.
Bleed the clutch hydraulic system thoroughly after any disassembly to prevent air bubbles and ensure firm pedal feel.
