To service your 2008 Ford F-150, use Mobil 1 Synthetic Transmission Fluid Dexron/Mercon. First, ensure the vehicle is on a level surface and open the hood. Locate the transmission fluid reservoir, typically near the transmission, and find the dipstick. Pull it out, clean it, reinsert it, and pull it out again to check the fluid level. Note the amount and top it off using a funnel until it reaches the full mark. Avoid overfilling the reservoir. Secure the container and you're all set to hit the road.
In many instances, you can determine the correct fluid type by checking the dipstick. For the 2008 Ford F-150, it's recommended to use transmission fluid that meets the Mercon V specifications.
Ford recommends using Mercon V transmission fluid. The specific brand of Mercon V is not crucial, but opting for a synthetic variant is preferred.
Did you remember to remove the old o-ring from the transmission when you replaced the filter?
Andrew Mercon V and Mercon 5 are identical. If the trucks have high mileage, avoid making any changes. Visit Fordtechmakuloco's YouTube channel for instructional videos on repairing and maintaining vehicles.
Can someone please help with a transmission issue I'm having? My dipstick shows "MERCON 5" written in Roman numerals, but the dealership told me it should take "MERCON V" based on the VIN. I did an oil and filter change, but now my Overdrive (O/D) and transmission fault lights are blinking. I'm considering flushing out all the fluid in the transfer case and transmission and starting fresh with either MERCON LV or MERCON 5. I've tried getting advice from different auto shops, but they all give conflicting suggestions. Any help would be greatly appreciated. Thank you!
