Ever wanted Overdrive?

I installed a Tremec TKO-600 5spd. in my Barracuda and I have to say it was the best modification that I made to the car. With a 2.87 first gear, the 3.91 rear end is more like a 4.23 while fifth gear at a .64 ratio lets me cruise the interstate at nearly 70 mph at only 2200 rpm. The overdrive transmission really transforms the car.
