2018 Ford F-150
2018 Ford F-150 transmission dry-fill capacity, plus transfer and axle fluid from the same capacity tables. Some fluid names are omitted.
Difficulty, time, and cost are estimates when this guide gives them. Torque is a cited figure, or it is left off.

The fluid named for that section
The 3.3L, 3.5L, and diesel sections say to use only MERCON ULV in a transmission that requires it. The 2.7L and 5.0L fluid name is left off this page.
| Item | Figure | Where it comes from |
|---|---|---|
| Automatic transmission, dry fill | 13.1 qt (12.4 L) in the 2.7L, 3.3L, 3.5L EcoBoost, 5.0L, and 3.0L diesel capacity tables. Approximate dry fill. Actual amount may vary during a fluid change. | Automatic transmission fluid row in each engine capacity table |
| 3.3L, 3.5L EcoBoost, and 3.0L diesel fluid | MERCON ULV. Motorcraft MERCON ULV, WSS-M2C949-A, XT-12-QULV. Those sections say a transmission that requires MERCON ULV should use only MERCON ULV. | Materials blocks and closing notes for the 3.3L, 3.5L EcoBoost, and 3.0L diesel |
| 2.7L and 5.0L fluid name | Omitted. Those sections print the same 13.1 qt dry fill, and the materials text contains both MERCON ULV and MERCON LV without a clean assignment. | 2.7L and 5.0L materials blocks |
| Transmission code on the label | Code 6 is the six-speed automatic 6R80. Code G is the ten-speed automatic 10R80. The code is on the Safety Compliance Certification Label. | Transmission code designation |
| Transfer case | 1.5 qt (1.4 L) for Electronic Shift-on-the-Fly and for Automatic four-wheel drive (Torque on demand). MERCON LV, WSS-M2C938-A. U.S. and Mexico XT-10-QLVC. Canada CXT-10-LV12. | Transfer case rows in the engine capacity and materials tables |
| Front and rear axle, gasoline engines | Front 3.5 pt (1.7 L). Rear 5.5 pt (2.6 L). SAE 75W-85, WSS-M2C942-A, XY-75W85-QL. | 2.7L, 3.3L, 3.5L, and 5.0L capacity and materials tables |
| Front and rear axle, 3.0L diesel | Front 1.8 qt (1.7 L). Rear 2.7 qt (2.6 L). SAE 75W-85, WSS-M2C942-A, XY-75W85-QL. | 3.0L diesel capacity and materials tables |
| Brake fluid | Motorcraft DOT 4 LV High Performance Brake Fluid, WSS-M6C65-A2, PM-20. Capacity is between MIN and MAX on the reservoir. | Brake fluid row in the capacity and materials tables |
Every engine capacity table in this printing lists automatic transmission fluid at 13.1 qt (12.4 L) and marks it approximate dry fill. A fluid change can take a different amount.
The 3.3L, 3.5L EcoBoost, and 3.0L diesel materials blocks name Motorcraft MERCON ULV, WSS-M2C949-A, XT-12-QULV, and the closing note says to use only MERCON ULV in a transmission that requires it.
Those two materials blocks also contain MERCON LV, WSS-M2C938-A, in the transmission area, and the closing note names MERCON LV. The page does not say which fluid belongs to code 6 or code G, so neither name is assigned here.
Transfer case capacity is 1.5 qt (1.4 L) of MERCON LV for both four-wheel-drive systems listed. Gasoline front and rear axles are 3.5 pt (1.7 L) and 5.5 pt (2.6 L) of SAE 75W-85. The diesel prints the same liters as 1.8 qt and 2.7 qt.
The certification label is how the manual says to identify the transmission. Code 6 is 6R80 and code G is 10R80. This page does not pair those codes with a fluid, because the code table and the fluid tables are separate. Brake fluid in the same materials tables is DOT 4 LV meeting WSS-M6C65-A2, kept between the reservoir marks.
