The mechanic I went to put Merk 5 in my transmission. He put a cheap alternative. I have to have it redone. 06 ford Fusion S takes FRN5 Motorcraft. I will have to take him to small claims court. If you mechanic prints the invoice and it's not listed in what he used,you will have to insist he added.

My Fusion manual says not to use Mercon V with FRN5 transmission. Only Motorcraft FNR5.I went to RockAuto and bought the Motorcraft FNR5 ATF. The Ford dealer says to use Mercon V ,but manual says NO. I have alot of miles on my car. I talked to the mechanic and he is going to drain out Mercon V ,and put Motorcraft FRN5 instead. The part # from the dealer is XT-9-QMM5,that's Mercon V. RickAuto is the same,but it says FRN5 Motorcraft on the front of the quart.

Thanks! I just happened to purchase a manual for my 06 Fusion S .Ford Motor Company, in my opinion doesn't care. RockAuto is right on! The manual makes it clear. The mechanic made a mistake. It's not his fault. I went with Haynes.
