I have the TKO 600 in my Macho TA. It works great with my 3.42 gears. At 72mph it is only turning 2000 rpm. Not that there is anything wrong with my TKO, but I am taking it out and putting in a 4l80e. Shifting is great but I drive a truck for a living and sometimes it is great just to put in drive and go !!!!!!!
