Changed out the Mercon LV ATF in my 2012 Ford Fusion SEL V6 a few days ago. Originally, I planned to get Mercon LV from Advance Auto parts, but they did not have any in stock, so I got Peak Full Synthetic Multi-vehicle (ATF) Automatic Transmission Fluid recommemded by them. It's said on the bottle that it is certified by Ford for Mercon LV applications. Later, I did some research and found two other certified products: Castrol/Transmax ATF full synthetic multi-vehicle transmission fluid available from Autozone and Silver State Dex VI / Mercon LV ATF.
I would have gone with Castrol if I had found that before making the purchase although the price is higher. I wonder if someone knows better licensed aftermarket alternatives.
I used a fluid extractor. About 4 to 5 quarts can be sucked out each time, as much as by removing the drain plug. I used 12 quarts of the Peak ATF following the instructions posted by drolds1 here.
About 10 to 20 percent of the original oil is still left using this method. The color changed from dark brown to pink, but I am not sure if the shift quality is better. There are still unsmooth shifts though. I have used Dr. Tranny instant shudder fixx but I have not seen any improvement yet. I plan to use Lubegard 63010 Platinum Universal ATF Protectant.
I am not sure if using Steeda CAI and tune exacerbated the transmission shudder. I wonder when I can request transmission rebuild since it's still under factory warranty.
