Symptoms and warning signs

Identifying the specific symptoms your 2017 Ford Taurus is exhibiting is the first step toward diagnosis. Pay close attention to these common indicators:

• RPM flare between gears: The engine RPMs momentarily increase significantly without a corresponding increase in vehicle speed during a gear change, as if the transmission is slipping before engaging the next gear.
• Harsh engagements or shifts: The transmission shifts with a noticeable jolt, thud, or bang, particularly when shifting into drive or reverse, or between forward gears.
• Slipping clutch feel: The engine revs but the vehicle doesn't accelerate proportionally, giving a sensation similar to a manual transmission clutch slipping.
• Delayed engagement: A significant pause or delay when shifting from Park to Drive or Reverse.
• Lack of power or sluggish acceleration: The vehicle feels underpowered, especially when trying to accelerate.
• Transmission warning light: The dashboard warning light may illuminate, indicating a fault detected by the Powertrain Control Module (PCM) or Transmission Control Module (TCM).
• Unusual noises: Whining, clunking, or grinding sounds coming from the transmission area.

How to verify and confirm the issue

Confirming a transmission issue in your 2017 Ford Taurus involves a combination of driver observation, fluid checks, and potentially diagnostic tools.

• Check transmission fluid level and condition: With the engine warmed up and running (in Park, on level ground, consult your owner's manual for specific procedure), check the transmission fluid dipstick. Is the fluid level correct? Is it bright red and translucent, or dark brown/black with a burnt smell? Burnt fluid is a strong indicator of internal wear.
• Observe shift patterns during a test drive: Drive the vehicle under various conditions (light acceleration, hard acceleration, uphill, downhill) and note exactly when and how the symptoms occur. Does it happen in specific gears? Is it worse when cold or hot?
• Scan for diagnostic trouble codes (DTCs): Use an OBD-II scanner to check for any stored or pending transmission-related codes (e.g., P07xx series codes). Even if the check engine light isn't on, codes might be stored. Live data from a professional scanner can also show transmission fluid temperature, gear commanded vs. actual, and solenoid operation.
• Review Technical Service Bulletins (TSBs): Ford occasionally releases TSBs for known issues. A quick search for TSBs related to 2017 Ford Taurus transmission shifting problems might reveal a known pattern or specific repair procedure.

Common causes (most likely first)

Several factors can lead to transmission slip, flare, or harsh shifts in a 2017 Ford Taurus:

• Low or degraded transmission fluid: The most common culprit. Low fluid prevents proper hydraulic pressure, while old, burnt fluid loses its lubricating and cooling properties, leading to excessive wear and poor shifting.
• Faulty transmission solenoids: Solenoids control the flow of transmission fluid to engage different gears. A stuck or failing solenoid can cause delayed, harsh, or slipping shifts.
• Worn valve body: The valve body directs fluid pressure to the clutch packs. Internal wear or blockages in the valve body can lead to incorrect pressure and shifting issues.
• Internal clutch pack wear: Over time, the friction material on the clutch packs can wear down, leading to slipping as they can no longer hold power effectively.
• Transmission Control Module (TCM) issues: The TCM (often integrated into the PCM) can develop software glitches or hardware failures that disrupt proper shift logic.
• Torque converter problems: While less common for just slipping or harsh shifts, a failing torque converter can contribute to a lack of power transfer and sometimes delayed engagement.

Step-by-step diagnosis and fixes

Addressing these issues requires a systematic approach:

1. Start with the basics: Fluid check. Verify the fluid level and condition. If low, top it off with the correct Ford-specified fluid. If burnt and dark, a fluid and filter change is a good first step, but be aware it might not resolve issues caused by existing internal damage.
2. Scan for codes. Use an OBD-II scanner to pull any diagnostic trouble codes. Research these codes to understand their specific meaning for a 2017 Ford Taurus. For more detailed information on various repair guides, you can visit our All repair guides section.
3. Inspect wiring and connectors. Check the transmission's external wiring harness and connectors for damage, corrosion, or loose connections, especially to solenoids and sensors.
4. Test solenoids (if accessible/diagnosable). Some solenoids can be tested for resistance or operation with a multimeter, though this often requires dropping the transmission pan.
5. Evaluate valve body operation. This typically requires specialized diagnostic equipment and expertise to measure line pressures and observe valve movement.
6. Consider internal inspection. If external checks and fluid changes don't resolve the issue, internal inspection of clutch packs and other components may be necessary, which means removing the transmission.

Repair options and cost factors

Repair options for transmission slip, flare, or harsh shifts in a 2017 Ford Taurus vary widely depending on the root cause:

• Transmission fluid and filter change: The least expensive option, suitable for issues caused by degraded fluid. This is a maintenance item that can sometimes resolve minor shifting issues.
• Solenoid replacement: If a specific shift solenoid is faulty, replacing individual solenoids is possible and less costly than a full rebuild.
• Valve body repair/replacement: A new or remanufactured valve body can address issues related to internal hydraulic control. This is a more involved repair.
• Transmission rebuild: For extensive internal wear (clutch packs, bands, planetary gears), a transmission rebuild involves disassembling the unit, replacing worn components, and reassembling it. This is a significant repair.
• Transmission replacement: In cases of severe damage or when a rebuild is not cost-effective, replacing the entire transmission with a new, remanufactured, or used unit is an option. For information on other vehicle models and their common issues, you can browse our Browse vehicles page.

Cost factors include parts prices, labor rates, the extent of the damage, and whether you opt for OEM, aftermarket, or used components. Early diagnosis can often prevent minor issues from escalating into major, more expensive repairs.

When to see a professional

While some basic checks like fluid level can be done at home, diagnosing and repairing transmission issues often requires specialized tools, knowledge, and experience. If you're unsure about the cause, if the problem persists after basic checks, or if you're dealing with internal components, it's highly recommended to consult a qualified automotive technician. Transmission work is complex and mistakes can lead to further damage.

Frequently asked questions

Can low transmission fluid cause a 2017 Ford Taurus to shift harshly?
