I have a 2000 Mustang GT with an automatic tranny. I found a 5 speed tranny from a 2001 Mustang Cobra. its the 3650. would it fit my car? What would i need? its comes with the bell housing, main tranny body, shifter etc.. i dont know a whole lot about tranny swap, and its going for 399, is this a good deal? only had 66,000 miles on it and ran perfectly fine when removed.
