How to Change Transmission Fluid on a 2018 Ford Expedition (10-Speed Automatic)
Step-by-step drain/fill or pan-drop service with tools, fluid spec, temp-based level check, and safety tips


đź”§ Expedition - Transmission Fluid Change
Your Expedition’s transmission fluid service method depends on which transmission you have and whether you’re doing a simple drain-and-refill or removing the pan and filter. On these newer Ford automatics, fluid level is set through a level/check plug at a specific transmission temperature (there is usually no dipstick).
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours
⚠️ Safety & Precautions
- ⚠️ Work on a level surface; support with jack stands before going underneath.
- ⚠️ Transmission fluid can be hot; let it cool and wear gloves/eye protection.
- ⚠️ Keep the engine running only when instructed for the level-check step.
- ⚠️ Do not crawl under a vehicle supported only by a jack.
đź”§ Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks
- Safety glasses
- Nitrile gloves
- Drain pan (at least 10-quart)
- Fluid transfer pump
- OBD2 scan tool with transmission fluid temperature data (specialty)
- Socket set (metric)
- Torx bit set
- Torque wrench (in-lb and ft-lb)
- Trim clip tool

đź“‹ Before You Begin

- Plan to monitor transmission fluid temperature with a scan tool; the level check depends on temperature.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Quick confirmation (so I give the exact Ford procedure)
- Are we talking about your Expedition with the 10-speed automatic (no dipstick), or does yours have a dipstick tube?
- Do you want a drain-and-refill only, or a pan drop + filter service—and do you have a scan tool that can read Transmission Fluid Temperature (TFT)?
Step 2: I’ll tailor the exact steps + correct fluid spec, fill/level temperature window, and torque specs
- Reply with the two answers above, and I’ll generate the complete, manufacturer-correct procedure for your Expedition.
âś… After Repair
- Verify there are no leaks with the engine running.
- Road test, then recheck for leaks.
