Autostick, that intriguing blend of automatic and manual transmission, offers a unique driving experience. It allows you to control gear changes like a manual transmission, but without the need for a clutch pedal. However, mastering Autostick requires understanding its nuances. This comprehensive guide will walk you through everything you need to know, from basic operation to advanced techniques.
Understanding Autostick Functionality
Autostick isn't a standalone transmission type; it's a feature integrated into an automatic transmission. The core automatic transmission still handles clutch engagement and disengagement automatically. Autostick simply gives the driver the ability to override the transmission's computer-controlled shifting logic. This means you're not directly controlling the clutch, just the gear selection.
Different manufacturers may implement Autostick (or similar systems like Tiptronic, Manumatic, etc.) slightly differently, but the core principles remain the same. Consult your vehicle's owner's manual for specific instructions related to your model.
Basic Operation: Shifting Up and Down
The Autostick gear selector is typically a gate-style shifter, similar to a standard automatic transmission, but with a "+" (plus) and a "–" (minus) sign or buttons on the shifter itself, or even paddle shifters mounted on the steering wheel.
- Shifting Up (+): To shift to a higher gear, gently push the shifter towards the "+" sign (or press the "+" button/paddle). The transmission will upshift to the next higher gear.
- Shifting Down (–): To shift to a lower gear, gently push the shifter towards the "–" sign (or press the "–" button/paddle). The transmission will downshift.
Important Note: The transmission will prevent you from downshifting into a gear that would cause engine damage (e.g., downshifting to first gear at high speed). It will either ignore the command or automatically select a safer gear.
Advanced Autostick Techniques
While basic upshifting and downshifting are straightforward, mastering Autostick involves understanding these advanced techniques:
Engine Braking
Engine braking utilizes the engine's resistance to slow the vehicle down, especially useful on downhill grades. By downshifting with Autostick, you engage the engine's compression, helping to control speed and reduce brake wear. This requires anticipating downhill sections and proactively downshifting before the speed becomes excessive.
Maximizing Acceleration
In situations requiring maximum acceleration, such as overtaking, judicious use of Autostick can provide quicker acceleration than letting the automatic transmission handle the shifts. Keeping the engine in its power band by holding lower gears for longer can significantly improve performance. However, remember to upshift before reaching the redline to avoid engine damage.
Improving Fuel Efficiency
Contrary to popular belief, using Autostick doesn't necessarily improve fuel economy. Aggressive driving in any gear can reduce fuel efficiency. However, using Autostick to avoid unnecessary downshifts in higher gears (especially on flat roads or gentle inclines) can potentially contribute to better fuel economy.
Troubleshooting Common Issues
- Shifter unresponsive: Ensure the vehicle is moving at a suitable speed for gear changes. Very low speeds may prevent downshifting. Also, check your owner's manual for speed limitations.
- Unexpected gear changes: The automatic transmission will still override Autostick commands in certain situations (e.g., low engine speed, high-speed downshift attempts). This is a safety feature.
- Rough shifting: This can be due to several factors, including low transmission fluid or mechanical issues within the transmission. Consult a mechanic if rough shifting persists.
Conclusion
Autostick offers a unique driving experience, allowing for a degree of manual control without the complexities of a traditional manual transmission. Mastering Autostick involves understanding its limitations and using its capabilities strategically. Remember to always consult your vehicle's owner's manual for specific instructions and safety recommendations. By practicing and understanding these techniques, you can fully enjoy the benefits of Autostick in your vehicle.
