Thanks John ! That's one smooth Tranny :thumb:John Hennessey said:Jeff - congrats on the big dyno numbers and a beautiful motor. The installed cost for our 4-speed auto transmission is $19,500. The nice thing about this system is that it can be driven as an every day car, drive around town or on the freeway (80 mph = 2500 rpm). And at the same time you can take it to the dragstrip and run 3-5 tenths quicker than you could with the 6-speed.
