i only use good DOT tires...ET Streets, M&H racemaster, Sportsman pro....
An AOD needs a 4.56 gear to equal 1st gear takeoff power of a 5-speed w/ 3.08's.
AOD=1st=2.40
T5=1st=3.35
Multiply by ring and pinion to get total gear.
Installation is about $200 and the gear is about $175
You can get a used gear for $75-100 if you wanted to save a few bucks but there is some risk.
