How much is a new transmission for a Ford Flex?

A brand-new or rebuilt transmission replacement for a Ford Flex typically runs in the low-to-mid five-figure range installed, with remanufactured units offering a more affordable path. In general, expect about $3,500 to $6,000 installed, while factory-new transmissions can push higher depending on availability and region.

The Ford Flex, produced from 2009 through 2019, uses a six-speed automatic transmission. Because the model was discontinued, factory-new Ford-branded units are harder to source, so many owners turn to remanufactured OEM or aftermarket options. Final prices depend on the exact transmission model for the year, labor costs in your area, and whether ancillary components must be replaced during the job.

What affects the price of a Ford Flex transmission

Several factors influence the final installed price, from the type of unit to regional labor costs.

Unit type and supplier

Options range from factory remanufactured transmissions to aftermarket rebuilt units or brand-new factory parts if available. Each type has a different price point and warranty coverage.

• New OEM transmission (rare and typically expensive)


• Remanufactured OEM transmission from Ford or a certified supplier


• Remanufactured/rebuilt aftermarket transmission from third-party vendors


• Used or pulled-from-demonstrator transmissions (not common for install, usually not preferred)

Factors like warranty term, core charges, and availability affect the final cost. The presence of a torque converter, new sensors, or cooling lines can add to the price.

Typical price ranges for a Ford Flex transmission, installed

Before considering the list, note that prices are always estimates and can vary by region and shop. The following ranges reflect installed costs as of 2024–2025 and may have changed since.

• Remanufactured OEM transmission installed: roughly $2,800–$4,800 for the unit plus labor


• Factory-new OEM (if available) installed: roughly $4,000–$7,000 or more for the unit plus labor


• Aftermarket rebuilt/transmission from third-party vendor installed: roughly $2,500–$4,500 for the unit plus labor

Installation labor can vary widely; typical labor costs range from about $800 to $1,800, depending on local rates and whether the job requires extra work (new seals, cooler lines, transmission fluid, and a possible torque converter replacement).

What to expect during the repair process

Replacing a Ford Flex transmission usually involves: removing the transmission from the engine bay, inspecting the torque converter and cooling lines, replacing worn components, reusing or replacing the transmission’s electronics, and testing the vehicle after installation.

Summary

In short, a full transmission replacement for a Ford Flex is a significant repair with a price typically ranging from about $3,000 to $6,000 installed, depending on whether you choose a remanufactured OEM unit or a factory-new part, plus labor and any necessary ancillary components. Because the model is no longer produced, most owners opt for remanufactured units from Ford or third-party shops, which balances price and reliability. Always obtain written quotes that itemize the unit, labor, and any extra parts, and verify warranty coverage.

What are the most common problems with the Ford Flex?

Common problems with the Ford Flex include issues with the power transfer unit (PTU) and transmission fluid leaks, broken center console latches, a faulty A/C fan control, and problems with the power liftgate and door lock sensors.

• Power transfer unit (PTU) and transmission leaks: Leaks are frequently reported in the axle area. This can involve either the transmission fluid or the PTU fluid. 
• Broken center console latch: The latch that secures the center console is a common point of failure. 
• A/C fan control: The fan speed may change erratically on its own. 
• Power liftgate and door sensors: The power liftgate can malfunction, and the door ajar warning light may illuminate even when the doors are closed, often due to faulty door lock sensors. 
• Exhaust system: Problems can arise with various components, including the muffler, exhaust manifold, and catalytic converter. 
• Front-end and suspension: Some models experience premature wear on front-end parts, leading to clunking noises and issues with wheel bearings, ball joints, and control arm bushings. Struts are also frequently mentioned as needing replacement. 
• Electronics: Owners report issues with the backup camera occasionally blacking out, and the electronic power steering can be problematic. 
• Alternator and fuel pump control module: These components have been identified as common failure points, particularly in certain model years. 
• Water pump: Some models, especially those with the 3.53.53.5L V6 engine, have reported water pump leaks that can lead to coolant loss. 

What this means for you

• Regularly check for fluid leaks around the axles. 
• Listen for any unusual noises coming from the engine, A/C, or suspension. 
• Be aware that electronic components, particularly the power liftgate and door sensors, are known to fail and may require costly repairs. 
• If buying a used Ford Flex, carefully inspect the vehicle for signs of these issues, especially in the areas mentioned above.

How much does Ford charge for transmission replacement?

A Ford transmission replacement can cost anywhere from $3,000 to over $8,000, depending on the specific vehicle, parts (new, remanufactured, or used), and labor. Automatic transmissions are typically more expensive than manual ones due to their complexity. Costs can vary significantly based on whether you use a dealership or an independent shop, the complexity of the transmission system, and the availability of parts. 
Cost breakdown and factors

• Total cost: A full replacement, including parts and labor, can range from approximately $3,000 to over $8,000. 
• Parts vs. labor: The cost of the transmission itself (parts) can be anywhere from $1,500 to over $7,000. Labor costs can add an additional $500 to $1,500 or more. 
• Manual vs. automatic:
  • Manual: Generally less expensive to replace. Parts can range from $1,500 to $4,000, with labor around $280 to $900. 
  • Automatic: More expensive due to increased complexity. Parts can range from $2,500 to $6,000+, with labor adding $420 to $1,500+. 
• Type of replacement part:
  • New/Dealer parts: Often the most expensive option but typically come with a manufacturer's warranty and are installed by trained technicians. 
  • Remanufactured/Rebuilt: A common option, often with a warranty, but cheaper than new. The total cost could be around $3,500-$5,500 for the part and labor at a $150/hr rate, according to JustAnswer. 
  • Used: The least expensive option, but with a shorter warranty (e.g., 1 year). 
• Labor and location: Labor costs vary depending on the shop and your geographic location. Dealerships often have higher labor rates but may offer more specialized service. 
• Additional parts: It's important to budget for other related parts, such as transmission fluid and filters, and sometimes a new transmission oil cooler, which may be required for the warranty to be valid. 

What you can do

• Get multiple quotes: Obtain estimates from both a dealership and independent shops to compare prices for new, remanufactured, and used parts. 
• Ask about warranties: Inquire about the warranty offered for both the parts and the labor. This can be a significant factor in deciding between a used, remanufactured, or new transmission. 
• Consider a transmission rebuild: Ask if rebuilding your current transmission is a viable option. It may only be $1,000-$2,000 less than a replacement but can be a good choice for those on a budget, as explained in Reddit discussions. 

Is it worth replacing a transmission?

Whether replacing a transmission is worth it depends on a cost-benefit analysis of the vehicle's age, its total value, the cost of the replacement, and your own plans for the car. If the repair cost is less than 30-40% of the car's current value, or if you plan to keep the vehicle for several more years, replacement may be a good investment. However, if the car is older and has other issues, or if the replacement cost is close to or exceeds the car's worth, it may be better to consider selling the vehicle. 
Factors to consider 
This video explains the factors to consider when deciding whether to replace your car's transmission: 42sNexologyYouTube · Sep 4, 2025

• Vehicle's value: Compare the cost of replacement to the car's current market value. If the repair is more than 30-40% of the car's worth, it may not be a good financial decision. 
• Vehicle's condition: If the rest of the car is in good condition with no major issues, a transmission replacement can be a worthwhile investment. However, if the car has many other problems, it may be better to cut your losses. 
• Your plans for the car: If you plan to keep the vehicle for several more years, replacing the transmission is more likely to be worth the cost. If you only plan to keep it for a year or two, it may not be. 
• Cost of the replacement: Costs can range from $1,500 to over $8,000, depending on the vehicle and the type of transmission (new, rebuilt, or used). Be sure to factor in labor costs as well. 
• Reliability of the model: Some car models have a history of transmission problems, which may make replacement less desirable. 

Options for replacement

• New transmission: This is often the most expensive option, but it comes with a new warranty. 
• Remanufactured transmission: A remanufactured unit has been rebuilt to "as-new" condition and often comes with a good warranty, making it a solid choice. 
• Used transmission: This is the cheapest option but comes with the highest risk, as you don't know its history. It is generally not recommended unless you can test it first.
