at 160k, my tranny will soon need a replacement, about 2grand from the dealer, 1800 for an art carr, money is tight,so i thought about a junkyard piece low mileage, when i do it, and add a shift recal before install, my question is does it have to be from a mark? can I use a Mustang one ? let me know, mustangs are easier to find, how bout crown vic or t bird or grand marquis let me know.
