The 2008 Smart Fortwo offered a unique driving experience, especially for those who opted for the manual transmission. While often described as an “automated manual,” understanding its nuances can unlock a surprisingly engaging and efficient driving style. This guide provides a deep dive into operating, maintaining, and troubleshooting the 2008 Smart Car manual transmission. Whether you’re a new owner or a seasoned driver, you’ll find valuable insights here. Let’s explore the intricacies of this distinctive gearbox.

Understanding the 2008 Smart Car Transmission System

The 2008 Smart Fortwo’s transmission isn’t a traditional manual. It’s a single-clutch automated manual, meaning there’s no clutch pedal. An electronic control unit (ECU) manages clutch engagement and gear shifts, but you still manually select the gears using the gear lever or optional paddle shifters. This system provides a blend of fuel efficiency and driver control.

Key Components of the Transmission

• Gear Lever/Paddle Shifters: Used to select the desired gear.
• Actuator Motor: Electronically engages and disengages the clutch.
• ECU (Electronic Control Unit): Controls the transmission based on driver input and sensor data.
• Transmission Fluid: Lubricates and cools the transmission components.

Operating Your Smart Car Manual Transmission

Driving a Smart Fortwo with the manual transmission requires a slightly different technique than a traditional manual car. Here’s a step-by-step guide:

1. Starting the Engine: Ensure the gear lever is in neutral (N). Turn the ignition key.
2. Selecting a Gear: Move the gear lever to ‘1’ for first gear. You can also use the paddle shifters to select first gear;
3. Accelerating: Gently press the accelerator pedal. The ECU will automatically engage the clutch, and the car will begin to move.
4. Shifting Gears: Lift your foot slightly off the accelerator, and then move the gear lever to the next desired gear (2, 3, 4, 5). The ECU will disengage the clutch, allowing the gear change. Remember to smoothly reapply the accelerator.
5. Downshifting: Similar to upshifting, lift your foot off the accelerator and move the gear lever to a lower gear. The ECU will manage the clutch and engine speed;
6. Stopping: Apply the brakes. You can downshift through the gears as you slow down, or simply allow the car to come to a stop in the current gear. The ECU will automatically disengage the clutch to prevent stalling. Shift to neutral (N) when stopped for an extended period;

Maintenance and Troubleshooting: Keeping Your Smart Car Shifting Smoothly

Regular maintenance is crucial for the longevity and performance of your Smart Car’s transmission. Here’s a breakdown of key maintenance tasks and potential issues:

Regular Maintenance Schedule

Maintenance Task	Frequency	Description
Transmission Fluid Check	Every 15,000 miles	Check the fluid level and condition. Top up if necessary.
Transmission Fluid Change	Every 30,000 miles	Replace the transmission fluid to ensure optimal lubrication and cooling.
Clutch Actuator Inspection	Every 45,000 miles	Inspect the clutch actuator for wear and tear.
Software Updates	As needed	Keep the ECU software updated for optimal transmission performance.

Common Issues and Solutions

• Jerky Shifting: Could indicate low transmission fluid, a faulty clutch actuator, or software issues. Check fluid levels, inspect the actuator, and consult a mechanic for software updates.
• Difficulty Shifting: May be caused by a failing clutch actuator or low transmission fluid. Inspect the actuator and check fluid levels.
• Transmission Slipping: Indicates a serious problem, possibly worn clutch plates or internal damage. Consult a qualified mechanic immediately.
• Warning Lights: If the transmission warning light illuminates, have the car diagnosed by a mechanic as soon as possible.
