do 4.10 or leave it stock
what do you have now ? 3.27 ? i did a 3.73 in an AOD from 3.27 and it didnt even feel like i swapped, you want a 3 gearet step up to even feel it. i like 4.10's in my 5 speed cars....i wont use anything less
also....that 2100 is way low, it probably flashes about 1700 doesnt it ? mustangs are light and relatively low HP so advertised stall speed is not a good indicator
i'll never do another AOD, but if did....id do minimum 3k stall and probably 4.30's
i suggest a 3k stallion from precision, a "good" oil cooler , and 4.10's
door code for gears is m=2.73 z=3.08 e=3.27
