Vehicle: 2020 Lincoln Aviator Reserve

Hey everyone, I've got a 2020 Lincoln Aviator Reserve with about 65,000 miles on it. I'm trying to be proactive with maintenance, and I'm wondering about the transmission fluid.

The owner's manual seems a bit vague, or maybe I'm just missing it. What's the recommended interval for changing the transmission fluid on these?

Also, what specific type of fluid does it take? I'm considering doing it myself if it's not too complicated, but I want to make sure I have all the right info first. Any advice or experiences with this would be greatly appreciated!

Hi Sarah, that's a great question and it's smart to be proactive with your 2020 Lincoln Aviator Reserve's transmission maintenance. Modern transmissions, especially in luxury vehicles like the Aviator, often come with "lifetime" fluid claims, which can be misleading.

Here's what you should know:

  1. Fluid Type: Your 2020 Lincoln Aviator, equipped with the 10R60 automatic transmission, requires Motorcraft MERCON® ULV Automatic Transmission Fluid. Using any other fluid can lead to premature wear and transmission issues.
  2. Service Interval: While Lincoln's official stance might suggest a "lifetime fill," many experienced technicians and enthusiasts recommend a fluid and filter change between 60,000 to 100,000 miles, especially if you engage in severe duty driving (e.g., frequent towing, heavy city traffic, or driving in extreme temperatures). For your 65,000 miles, it's a good time to consider it.
  3. DIY Feasibility:
    • Complexity: Changing the transmission fluid on the 10R60 transmission is not a simple DIY task for most owners. These transmissions do not have a traditional dipstick. The fill procedure involves specific steps, including monitoring the transmission fluid temperature with a diagnostic scan tool to ensure proper fluid level.
    • Tools Required: You'll need specialized tools, including a scan tool capable of reading transmission fluid temperature, a fluid transfer pump, and potentially a lift to access the pan comfortably.
    • Filter: It's highly recommended to replace the transmission filter when changing the fluid.

When to See a Shop: Given the complexity and the need for precise temperature monitoring during the fill procedure, we strongly recommend having this service performed by a qualified Lincoln dealership or an independent shop specializing in Ford/Lincoln transmissions. They have the correct tools, fluids, and expertise to ensure the job is done right, preventing potential costly transmission damage from incorrect fluid levels or types. It's a significant investment in your vehicle's longevity.
