2017 Ford Transit 150 – Reliability, Maintenance, And DIY Solutions
The 2017 Ford Transit 150 is a versatile workhorse favored by contractors and van-life enthusiasts for its massive interior volume and modern driving dynamics. This guide provides a deep dive into the mechanical maintenance, common troubleshooting areas, and performance upgrades necessary to keep your van running at peak efficiency. Whether you are hauling gear to a job site or building a custom camper, understanding your Transit’s specific needs is the key to longevity.
Owning a full-size van requires a different mindset than maintaining a standard sedan or crossover. When you drive a 2017 ford transit 150, you are managing a high-roof or medium-roof machine designed for heavy-duty cycles and significant payloads.
You likely chose this vehicle for its reputation for utility and its relatively car-like handling. However, keeping that performance consistent requires staying ahead of specific Ford-specific quirks and maintenance intervals.
This article provides the roadmap you need to master your van’s upkeep. We will cover everything from engine diagnostics to suspension upgrades, ensuring your vehicle remains a reliable partner for years to come.
Choosing the Right Engine: 3.7L V6 vs. 3.5L EcoBoost
The 2017 ford transit 150 came primarily with two gasoline engine options, each offering a distinct driving experience. Understanding which one sits under your hood is the first step in any DIY diagnostic process.
The Reliable 3.7L Ti-VCT V6
The 3.7L naturally aspirated engine is the “old reliable” of the Transit lineup. It uses Twin Independent Variable Cam Timing to balance fuel economy and power without the complexity of turbochargers.
This engine is generally easier to work on for the average DIYer because the engine bay is less crowded. You should focus on regular coolant flushes and spark plug replacements every 60,000 to 100,000 miles to keep it idling smoothly.
The Powerful 3.5L EcoBoost V6
If your van has the 3.5L EcoBoost, you have a twin-turbocharged powerhouse that excels at towing and climbing steep grades. This engine provides significantly more torque, making the van feel much lighter than it actually is.
Owners must be diligent about oil change intervals with the EcoBoost. Turbochargers rely on clean, high-quality synthetic oil to prevent bearing failure and carbon buildup on the intake valves.
Maintaining Your 2017 ford transit 150 for Long-Term Reliability
Consistent maintenance is the only way to ensure your van reaches the 200,000-mile mark without a major breakdown. The 2017 ford transit 150 responds well to a proactive service schedule that goes beyond the basic “oil change when the light comes on” approach.
Oil and Filter Requirements
For the 3.7L engine, use 6 quarts of 5W-20 synthetic blend oil. The 3.5L EcoBoost requires 6 quarts of 5W-30, which provides better protection for the turbochargers under high heat.
Always use a high-quality Motorcraft filter or an equivalent that features a silicone anti-drainback valve. This prevents “dry starts,” which can cause premature wear on the timing chain and tensioners over time.
Transmission Fluid Service
The 6R80 6-speed automatic transmission in this van is exceptionally robust. However, Ford’s “lifetime” fluid claims should be viewed with caution if you frequently carry heavy loads or drive in stop-and-go traffic.
Drop the transmission pan and replace the filter and fluid every 60,000 miles. Use only MERCON LV fluid, as using the wrong specification can lead to erratic shifting or torque converter shudder.
The Critical Air Filter Check
One unique issue with this model year is the design of the cowl area. Rainwater can sometimes leak past the weatherstripping and drip directly onto the air filter housing, leading to a soaked filter and potential engine hesitation.
Inspect your air filter every few months for signs of moisture or mold. If you find water intrusion, consider applying a bead of automotive silicone to the cowl seams to redirect water away from the intake.
Addressing the Notorious “Giubo” Flex Disc Issue
One of the most discussed mechanical components on the 2017 ford transit 150 is the driveshaft coupling, often called the Giubo or flex disc. This rubber component sits between the transmission and the driveshaft to dampen vibrations.
Signs of a Failing Flex Disc
If you feel a significant vibration through the floorboards or hear a “clunking” sound when shifting into gear, inspect the flex disc immediately. Look for visible cracks, tears, or missing chunks of rubber in the circular coupling.
A total failure of this part can result in the driveshaft detaching while driving, which causes catastrophic damage to the undercarriage. Many owners opt to replace the rubber disc with a universal joint conversion kit for a permanent fix.
Safety First: Inspecting the Undercarriage
When you are under the van, check the center support bearing as well. If the rubber surrounding the bearing is dry-rotted, it will contribute to the same vibrations caused by a failing flex disc.
Always use jack stands and chock the wheels before crawling under your Transit. These vans are heavy, and safety should be your primary concern when performing DIY inspections.
Brake System Maintenance and Upgrades
Stopping a fully loaded 2017 ford transit 150 requires a healthy braking system. Because these vans are often used for delivery or heavy hauling, the front brake pads tend to wear out faster than those on a standard pickup truck.
Choosing the Right Brake Pads
Standard ceramic pads are quiet and produce low dust, but they may fade under heavy heat. If you frequently drive through mountainous terrain, consider heavy-duty semi-metallic pads for better heat dissipation.
When replacing pads, always inspect the rotors for “hat” rust or grooving. If the steering wheel shakes when you apply the brakes, your rotors are likely warped and need to be turned or replaced.
Brake Fluid Flush
Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This moisture can corrode the internal components of the ABS module and lower the boiling point of the fluid.
Flush the brake system with fresh DOT 4 fluid every two years. This is a simple DIY task that requires a vacuum bleeder or a helpful friend to pump the pedal while you open the bleeder valves.
Suspension and Handling Improvements
The factory suspension on the T-150 is designed for a balance of comfort and utility. However, if you have converted your van into a camper or carry a permanent tool rack, the rear leaf springs may start to sag.
Adding Helper Springs or Airbags
To improve stability in crosswinds and reduce sagging, many owners install SumoSprings or air helper kits. These components bolt onto the frame and provide extra support when the van is under load.
This modification significantly reduces “body roll” when cornering and keeps the headlights aimed correctly at the road instead of into the eyes of oncoming drivers. It is a game-changer for long-distance highway travel.
Upgrading Shocks and Struts
By the time a 2017 ford transit 150 reaches 80,000 miles, the factory shocks are often tired. Upgrading to a heavy-duty nitrogen-charged shock, like those from Bilstein or Fox, will dramatically improve the ride quality.
High-quality shocks help the tires maintain better contact with the road on washboard dirt tracks or pothole-filled city streets. This results in better traction and a much more composed driving experience.
Electrical System and Battery Care
Modern Transits are packed with electronics, from the SYNC infotainment system to various body control modules. A weak battery can cause a cascade of “ghost” codes and strange dashboard warnings.
The Under-Seat Battery Location
In the 2017 ford transit 150, the battery is located under the driver’s seat. To access it, you must slide the seat forward and remove the protective plastic cover. This makes jumping the vehicle or replacing the battery slightly more complex than in other vehicles.
If you plan to run accessories like a fridge or power inverter for camping, consider installing a dual-battery system with an isolator. This ensures your starter battery is never drained by your house loads.
Managing the Smart Charging System
Ford uses a smart charging system that adjusts alternator output based on battery age and temperature. If you replace the battery yourself, it is often necessary to perform a BMS (Battery Management System) reset.
This can usually be done using a scan tool or a specific sequence of flashing the high beams and pumping the brakes. Resetting the system tells the alternator that a new battery is present, preventing overcharging.
Frequently Asked Questions About 2017 ford transit 150
What is the towing capacity of a 2017 Ford Transit 150?
The towing capacity generally ranges between 5,000 and 7,500 pounds, depending on the engine and rear-axle ratio. Always check the door jamb sticker for your specific vehicle’s Gross Combined Weight Rating (GCWR).
How often should I change the spark plugs?
While Ford suggests a long interval, most experienced mechanics recommend changing spark plugs every 60,000 miles, especially on the 3.5L EcoBoost engine, to prevent ignition coils from overworking and failing.
Why is my Transit making a whistling sound at highway speeds?
This is often caused by the large side mirrors or a gap in the windshield molding. Check the plastic trim pieces around the A-pillar for any looseness and secure them with automotive-grade adhesive if necessary.
Can I fit 33-inch tires on my Transit 150?
Fitting larger tires usually requires a lift kit and some trimming of the front wheel well liners. Most owners find that a 245/75R16 tire is the largest size that fits comfortably without significant rubbing issues.
Final Thoughts for the DIY Owner
The 2017 ford transit 150 is a remarkably capable platform that rewards owners who pay attention to the details. By handling your own oil changes, monitoring the flex disc, and keeping the air intake dry, you can avoid the most common pitfalls associated with this model.
Remember that a van this size requires specialized tools, such as a heavy-duty floor jack and high-capacity jack stands. Never compromise on safety when working on a vehicle that weighs several tons.
Whether you are using your Transit for a cross-country adventure or as the backbone of your small business, a proactive maintenance mindset will save you thousands of dollars in the long run. Stay safe and stay on the road!
