What is the transmission problem on a 2017 Chevy Impala?

Yes — the 2017 Chevrolet Impala has been associated with transmission issues such as slipping, harsh or delayed shifts, and hesitation during acceleration.

These symptoms can affect both 4-cylinder and V6 models equipped with GM’s 6-speed automatic transmission. The problem tends to appear as the vehicle ages or with higher mileage, and it can range from intermittent to persistent, sometimes triggering the transmission warning light or the check engine light.

What symptoms to look for

The following signs are commonly reported by Impala owners and can help you identify potential transmission trouble early.

• Slipping out of gear or RPMs rising without corresponding acceleration


• Harsh, abrupt, or delayed upshifts or downshifts


• Difficulty engaging Drive or Reverse or hesitation when moving


• Shudder or vibration during acceleration


• Unusual noises from the transmission or under the car during gear changes


• Check Engine or Transmission temperature warning lights

If you experience any of these symptoms, it's important to have the vehicle inspected promptly to prevent further damage and avoid getting stranded.

Why these symptoms occur

Shifting irregularities in the 2017 Impala can stem from a range of issues, from fluid problems to electronic controls. Understanding the potential roots helps frame the repair conversation with a technician.

Addressing the issue early can reduce the likelihood of more expensive repairs down the line and may improve the chances of a successful repair without a full transmission replacement.

Causes and potential fixes

There are several potential causes for transmission problems in the 2017 Impala. The following list summarizes common factors and the typical remedies used by technicians.

• Low or leaking transmission fluid: can cause slipping, overheating, and poor gear engagement. Remedy: locate and repair leaks, top up or replace fluid as needed, and verify proper level.


• Contaminated or old transmission fluid: reduces lubrication and performance. Remedy: fluid flush or replacement and new filters if applicable.


• Worn or damaged solenoids or valve body: can cause shifting irregularities. Remedy: solenoid/valve body service or replacement.


• Torque converter issues: can cause shudder, slipping, or inconsistent engagement. Remedy: torque converter replacement or rebuild in severe cases.


• Software/TCM calibration: outdated software can cause shifting delays or harsh shifts. Remedy: dealer software update or reflash of the transmission control module (TCM).


• Internal wear from high mileage: clutch packs and gears wear over time. Remedy: transmission rebuild or replacement in advanced cases.

In many cases, technicians will perform diagnostic scans, fluid checks, and pressure tests to identify the root cause and determine whether a repair is feasible or if replacement is warranted.

What this means in practice is that symptoms aren’t always caused by a single issue; multiple factors can contribute, and some repairs may be as simple as an oil change with a software update, while others could require major component work.

Common repair paths

Depending on the diagnosis, repair options may include fluid service, valve body or solenoid replacements, a software update, or, in more severe cases, a full transmission rebuild or replacement.

What to do if your Impala acts up

If you notice any symptoms described above, take these steps to protect the vehicle and prepare for service.

1. Check the transmission fluid level and condition (color, smell). If the level is low, address leaks and top up fluids as directed in the owner’s manual.


2. Note when the symptom occurs, the driving conditions, and whether warning lights are on.


3. Have the vehicle scanned for error codes (OBD-II). Codes related to the transmission can help pinpoint the issue.


4. Ask the dealer or a qualified shop to review any related GM service bulletins or recalls using your VIN.


5. Schedule a diagnostic appointment with a GM dealer or trusted transmission shop; avoid aggressive driving with a potential transmission issue.


6. Document maintenance history and mileage; if a repair is proposed, obtain an estimate and compare options (repair vs. replacement).

Prompt diagnosis and repair can prevent further damage, improve safety, and extend the life of your transmission.

Recalls, service notices, and how to check yours

GM and the NHTSA have issued recalls and service bulletins related to GM automatic transmissions in recent years, including some Impala models from the mid-2010s. Availability and applicability vary by VIN. Always check:

• NHTSA recall search by VIN: https://www.nhtsa.gov/recalls


• GM’s owner site and your vehicle’s VIN for service bulletins and software updates

If your VIN is listed for a recall or service bulletin, a dealer repair will be covered under recall or warranty terms. For vehicles not covered by a recall, a qualified shop can diagnose and service the transmission under standard maintenance or repair terms.

Summary

The 2017 Chevy Impala can experience transmission problems such as slipping, harsh or delayed shifts, and hesitation. Early symptom recognition, fluid checks, diagnostic scans, and timely dealer service or software updates can mitigate damage and extend the life of the transmission. Always verify recalls and service bulletins for your VIN and seek prompt professional evaluation when symptoms appear.

What happens right before your transmission goes out?

You can tell your transmission is about to go out by listening for strange noises like grinding or humming, and by experiencing symptoms like rough or delayed shifting, slipping out of gear, and a burning smell. Leaking reddish-brown fluid on the ground under your car is another strong indicator of a transmission problem. If you notice these signs, it's crucial to have a professional inspect the vehicle to prevent further damage. 
Signs of a failing transmission

• Strange noises: Listen for grinding, clunking, humming, whining, or buzzing sounds, especially when shifting or in neutral. 
• Rough or delayed shifting: You may feel a jolt, a delay, or a jerky sensation when the car changes gears. 
• Gear slipping: The transmission may randomly shift out of gear, or the engine may rev up without the car accelerating as it should. 
• Burning smell: A distinct burning smell can indicate that the transmission fluid is overheating and burning. 
• Leaking fluid: Look for red or brown fluid puddles under your car, which could mean a transmission fluid leak. 
• Warning lights: The "Check Engine" or other warning lights on your dashboard may illuminate, says Hogan & Sons. 
• Poor acceleration: The vehicle may feel sluggish or not accelerate as powerfully as it normally does. 

What to do
If you experience any of these symptoms, have a transmission specialist diagnose the issue immediately. Continuing to drive the car could lead to more severe and costly damage.
