If you're the proud owner of a Can-Am Commander, you already know it's a beast of a machine, capable of tackling tough terrain and handling demanding tasks. But even the toughest machines can have their quirks, and one of the most common complaints among Commander owners revolves around shifting problems. From stubborn gear engagement to outright refusal to shift, these issues can quickly turn a fun ride into a frustrating experience. This article dives deep into the common causes of these shifting woes, offering practical advice and troubleshooting tips to get you back on the trail.

Is Your Commander Fighting You When You Shift? You’re Not Alone!

Shifting problems on a Can-Am Commander are surprisingly common. They can manifest in several ways: difficulty shifting into gear (especially from park), gears grinding, popping out of gear, or even a complete inability to shift. Understanding the symptoms is the first step in diagnosing the problem. Think of it like this: your Commander is trying to tell you something is wrong. Ignoring it won't make it go away; in fact, it could lead to more serious and expensive damage down the line.

Digging Deeper: The Usual Suspects Behind Shifting Issues

So, what's causing your shifting headache? Here are the most common culprits:

  • Low or Contaminated Transmission Fluid: This is often the first place to look. Low fluid levels can starve the transmission of necessary lubrication, leading to difficult shifting and potential damage. Contaminated fluid, filled with debris or water, can also wreak havoc on the internal components.

  • Worn or Damaged Shift Linkage: The shift linkage is the mechanical connection between the shift lever and the transmission. Over time, the linkage can become worn, loose, or damaged, resulting in imprecise shifting or even complete failure to shift. Bushings can wear, rods can bend, and connections can loosen.

  • Clutch Problems (If Applicable): While the Commander utilizes a CVT (Continuously Variable Transmission), issues within the CVT system, particularly with the clutch components (driven and drive clutches), can indirectly affect shifting performance. A slipping or malfunctioning clutch can put undue stress on the transmission, making shifting difficult.

  • Internal Transmission Damage: This is the worst-case scenario, but it's a possibility. Internal damage to the gears, synchros, or other components can cause severe shifting problems. This often requires professional repair or even a complete transmission replacement.

  • Shift Cable Issues: The shift cable connects the shifter to the transmission. Over time, the cable can stretch, fray, or become kinked, leading to difficulty shifting or an inability to select certain gears.

  • Idle Speed Too High: An idle speed that's too high can make it difficult to shift into gear, especially from park. The engine is essentially trying to drive the transmission even when you're not pressing the gas pedal.

  • Faulty Shift Position Sensor: The shift position sensor tells the ECU (Engine Control Unit) which gear you've selected. A faulty sensor can lead to incorrect information being sent to the ECU, resulting in shifting problems.

Getting Your Hands Dirty: Troubleshooting Tips You Can Try Yourself

Before you rush to the mechanic, there are several things you can check and try yourself. These steps can often identify the problem and potentially save you time and money.

  1. Check the Transmission Fluid:

    • Locate the transmission fluid dipstick (refer to your owner's manual).
    • Wipe the dipstick clean and reinsert it fully.
    • Remove the dipstick again and check the fluid level. It should be within the "full" range.
    • Inspect the fluid's color and consistency. It should be clean and clear, not dark, murky, or milky. If it's low, add the correct type of transmission fluid (specified in your owner's manual). If it's contaminated, consider a fluid flush and filter change.

  2. Inspect the Shift Linkage:

    • Visually inspect the shift linkage for any signs of wear, damage, or looseness.
    • Check the bushings at the joints of the linkage. Replace any worn or cracked bushings.
    • Ensure that all connections are tight and secure.

  3. Adjust the Shift Linkage:

    • Many Commander models have adjustable shift linkages. Refer to your owner's manual for the proper adjustment procedure.
    • Slight adjustments can often improve shifting performance.

  4. Check the Shift Cable:

    • Inspect the shift cable for any signs of damage, such as kinks, fraying, or stretching.
    • Ensure that the cable is properly routed and secured.
    • Lubricate the cable with a silicone-based lubricant.

  5. Adjust the Idle Speed:

    • If your idle speed is too high, adjust it to the manufacturer's specifications (refer to your owner's manual).
    • This may require a scan tool to monitor the engine RPM.

  6. Check for Error Codes:

    • Use a scan tool to check for any error codes related to the transmission or shift position sensor.
    • Error codes can provide valuable clues about the cause of the shifting problem.

When to Call in the Pros: Knowing Your Limits

While some shifting problems can be resolved with basic troubleshooting, others require the expertise of a qualified mechanic. If you're not comfortable working on your machine, or if you've tried the above steps and the problem persists, it's time to seek professional help. Specifically, consider a mechanic if:

  • You suspect internal transmission damage.
  • You're not comfortable adjusting the shift linkage or idle speed.
  • You need to diagnose and repair electrical problems related to the shift position sensor or other components.
  • You lack the necessary tools or equipment.

Prevention is Key: Keeping Your Commander Shifting Smoothly

The best way to avoid shifting problems is to practice preventative maintenance. Here are some tips to keep your Commander shifting smoothly for years to come:

  • Regularly Check and Change the Transmission Fluid: Follow the manufacturer's recommended maintenance schedule for transmission fluid changes.
  • Lubricate the Shift Linkage: Periodically lubricate the shift linkage with a silicone-based lubricant.
  • Inspect the Shift Cable: Regularly inspect the shift cable for any signs of damage.
  • Avoid Abusive Driving: Avoid harsh shifting and excessive stress on the transmission.
  • Properly Store Your Commander: Protect your Commander from the elements to prevent corrosion and damage to the shift linkage and cable.

Frequently Asked Questions

  • Why is my Can-Am Commander hard to shift into gear? Low transmission fluid, worn shift linkage, or a high idle speed are common causes. Check these first and adjust as needed.

  • What kind of transmission fluid does my Can-Am Commander use? Refer to your owner's manual for the correct type of transmission fluid. Using the wrong fluid can damage the transmission.

  • How often should I change the transmission fluid in my Can-Am Commander? Follow the manufacturer's recommended maintenance schedule, typically every 100 hours of operation or annually.

  • Can I adjust the shift linkage on my Can-Am Commander myself? Yes, many Commander models have adjustable shift linkages. Refer to your owner's manual for the proper procedure.

  • What does a faulty shift position sensor do? A faulty sensor sends incorrect gear information to the ECU, leading to shifting problems.

Conclusion

Shifting problems on a Can-Am Commander can be frustrating, but with a little knowledge and some basic troubleshooting, you can often diagnose and resolve the issue yourself. Remember to start with the simple things, like checking the transmission fluid and shift linkage, and don't hesitate to seek professional help if you're not comfortable working on your machine. Regularly check your fluids and linkages to ensure optimal performance and longevity.
