That clunky, unyielding shifter is the only thing standing between you and a great day of riding. You’re not alone; this is a common headache for many owners.
We’ve all been there, and that’s exactly why we put together this guide. We promise to walk you through the entire diagnostic process, from the simple five-minute checks you can do with zero tools to the more involved steps that will help you pinpoint the exact cause of the problem.
In this article, you’ll get a complete can am commander not shifting guide. We’ll cover the most common culprits like linkage adjustments and faulty sensors, detail the step-by-step checks you need to perform, and even tell you when it’s time to put down the wrenches and call in a professional. Let’s get your machine back in action.
Why Won’t My Can-Am Commander Shift? Unpacking the Common Culprits
When your can am commander not shifting issue pops up, it almost always falls into one of three categories: a simple mechanical fault, an electrical gremlin, or a more complex clutch/transmission problem. Understanding these possibilities is the first step in an effective diagnosis.
Let’s break down the most common problems with can am commander not shifting, starting with the easiest ones to check.
H3: Simple Mechanical Issues: The Low-Hanging Fruit
Before you start worrying about expensive electronic parts, always check the physical connections first. These are often the source of the problem, especially after a rough ride.
The most frequent offender is the shift linkage. This is the rod that connects your shifter handle to the transmission. Over time, or after a hit from a rock or branch, it can get bent, pop off, or simply vibrate out of adjustment. When it’s not adjusted correctly, it doesn’t move the transmission lever far enough to actually change gears.
Another area to check is the shifter assembly itself. The internal components of the shifter in the cab can wear out, causing excessive slop and preventing a clean gear change.
H3: Electrical Gremlins: When Sensors Go Bad
Modern UTVs rely on a network of sensors to operate safely. If one of these sensors fails, it can prevent the machine from shifting as a safety precaution.
A faulty brake switch is a prime suspect. Your Commander needs to know that your foot is on the brake before it will allow you to shift out of Park. If the switch is broken, the computer never gets the signal, and you’re stuck.
The Gear Position Sensor (GPS) is another critical component. This sensor tells the vehicle’s computer and your dashboard display which gear you’re in. If it fails, the computer gets confused and may lock you out of shifting to prevent damage.
H3: Clutch and Transmission Problems: The Deeper Dive
If the mechanical and electrical checks don’t reveal the problem, it’s time to consider the clutch and transmission. These issues are more involved but are still common points of failure.
The CVT (Continuously Variable Transmission) clutch system can be a source of shifting woes. If the primary clutch doesn’t fully disengage at idle, it keeps tension on the belt and pressure on the transmission input shaft. This pressure makes it extremely difficult, if not impossible, to move the shift lever.
Finally, there’s the possibility of an internal transmission issue. This is the least common and most serious cause. Problems like a bent shift fork or damaged gears inside the gearbox are usually accompanied by grinding noises and are best left to an experienced mechanic.
Your Step-by-Step Diagnostic Guide for a Can-Am Commander Not Shifting
Ready to get your hands dirty? Follow this logical troubleshooting process. This section is your “how to can am commander not shifting” playbook. Grab your tools and let’s get started.
H3: Step 1: The Pre-Check (Don’t Skip This!)
First, ensure the scene is safe. Park your Commander on level ground, engage the parking brake, and turn the engine off.
- Visual Inspection: Get down and look. Follow the shift rod from the shifter to the transmission. Do you see anything obviously bent, disconnected, or covered in caked-on mud that could be restricting movement?
- Check the Basics: Are you firmly pressing the brake pedal when trying to shift? Is the engine RPM at a normal idle (not too high)? A high idle can cause the clutch to engage slightly, creating the same pressure that prevents shifting.
- Rock the Machine: Sometimes, the gears can be in a bind. With the machine off, gently rock it back and forth a few inches while trying to move the shifter. This can sometimes release the tension and allow it to shift.
H3: Step 2: Checking and Adjusting the Shift Linkage
This is the most common fix. You’ll likely need a set of metric wrenches (often 10mm, 12mm, or 13mm).
- Locate the Linkage: Find the adjustment points on the shift rod. There are typically threaded ends (heim joints or clevises) with lock nuts on either side.
- Check for Play: Have a friend move the shifter in the cab while you watch the linkage at the transmission. Is there a lot of slop before the transmission arm moves?
- Make Adjustments: Loosen the lock nuts. To adjust, you can either turn the center rod or unhook one end and turn the joint. Make small, half-turn adjustments at a time. The goal is to have the shifter in the cab line up perfectly with the gear detents on the transmission. Test after each adjustment until it shifts smoothly through all gears (R, N, H, L).
H3: Step 3: Testing the Electrical Components
If the linkage is fine, let’s look at the electronics. These are some simple but effective can am commander not shifting tips.
For the brake switch, the test is simple: press the brake pedal. Do your brake lights turn on? If they don’t, the switch is likely bad or out of adjustment. This is a cheap and easy part to replace.
For the Gear Position Sensor, look at your dash display. Turn the key to the “ON” position. Does the display correctly show “P” for Park? As you try to shift, does the display change, flash, or go blank? An incorrect or missing gear reading points directly to a faulty GPS or a wiring issue connected to it.
H3: Step 4: A Quick Look at the Clutch
With the machine in Neutral and the parking brake on, safely start the engine. Do not stand directly beside the clutches.
Watch the primary (front) clutch and the drive belt. At idle, the belt should be still or moving very slowly. If the belt is trying to aggressively spin, it means your primary clutch is partially engaged. This is often caused by worn-out rollers or a broken spring inside the clutch and will require disassembly to fix.
Essential Tools and Parts for the Job
Being prepared makes any job easier. Here’s a list of tools and common parts you might need to resolve your shifting issue.
- Basic Hand Tools: A good metric socket and wrench set, pliers, and a screwdriver set.
- Specialty Tools: A multimeter for testing electrical circuits like the brake switch and gear position sensor.
-
Common Replacement Parts:
- Shift Linkage Bushings or Heim Joints
- Brake Light Switch
- Gear Position Sensor (GPS)
Can-Am Commander Not Shifting Best Practices: Preventive Maintenance is Key
The best way to fix a problem is to prevent it from happening. Following a good can am commander not shifting care guide can save you a lot of trailside frustration.
H3: Regular Linkage Inspection and Lubrication
After every few rides, especially after a muddy one, take a moment to inspect your shift linkage. Ensure the nuts are tight and the joints are clean. A quick spray of a quality lubricant like WD-40 or a dry lube on the pivot points will keep things moving freely.
H3: Keeping Your Clutch Clean and Healthy
Your CVT clutch housing is not perfectly sealed. Belt dust and dirt can build up inside, causing premature wear on clutch components. Periodically remove the clutch cover and blow out the dust with compressed air. This simple step can dramatically extend the life of your clutches.
H3: The Eco-Friendly Approach to Maintenance
Practicing sustainable can am commander not shifting maintenance is about being smart and responsible. Choose high-quality, durable replacement parts. A well-made part lasts longer, which means less waste in the landfill and less time wrenching.
If your repair does require changing fluids like transmission oil, always capture the old oil in a sealed container and take it to an auto parts store or local recycling center. This eco-friendly can am commander not shifting practice protects the environment we all love to ride in.
When to Wave the White Flag: Knowing When to Call a Pro
DIY is great, but it’s crucial to know your limits. If you’ve gone through this guide and are still stumped, or if the problem points to something more serious, it’s time to call a qualified mechanic.
Call a professional if:
- You hear grinding, clunking, or other metallic noises from the transmission.
- You suspect an internal transmission failure (e.g., you’ve found metal shavings in the fluid).
- You are not comfortable performing electrical diagnostics with a multimeter.
- You’ve tried all the adjustments and still can’t get it to shift correctly.
Frequently Asked Questions About a Can-Am Commander Not Shifting
Why is my Commander stuck in Park?
This is the most common shifting issue. The top three causes are a misadjusted shift linkage, a faulty brake light switch that isn’t telling the computer the brake is applied, or a primary clutch that’s staying partially engaged at idle, putting pressure on the gearbox.
Can a weak battery cause shifting problems?
Yes, absolutely. Modern UTVs are heavily reliant on electronics. A weak or dying battery can provide low voltage, causing sensors, solenoids, and the ECU (Engine Control Unit) to malfunction, which can certainly lead to shifting issues.
How much does it cost to fix a shifting issue?
The cost can range from $0 to over a thousand dollars. A simple linkage adjustment is free. A new brake switch or sensor might cost you $50-$150 for the part. However, if the problem is internal to the transmission or requires a full clutch rebuild, the cost for parts and labor can climb significantly.
Is it hard to replace a Can-Am gear position sensor?
It’s a moderately difficult job for a DIYer. The sensor itself isn’t usually expensive, but its location on the side of the transmission can be tight and may require removing side plastics, the skid plate, and sometimes a wheel for easier access.
Tackling a can am commander not shifting problem can feel daunting, but it’s often a straightforward fix. By starting with the simplest solutions like checking your linkage and brake switch, you can solve the majority of issues without ever opening the toolbox. Remember to perform regular checks and maintenance to keep your machine reliable.
Now you’re armed with the knowledge to diagnose and fix the problem. Get it sorted, get back out there, and enjoy the trails. Stay safe and happy riding!
