I am pretty new to this, actually i never had a slapshift tranny before. The setup is a 350 with a small race converter, 3500 stall and a freddy brown tranny.(B&M shifter and shift kit) When i shift into drive, i can punch it up once and/or down twice. The only thing is i do not know wat it does so any help in this field would be greatly appreciated. Also while on the subject with the 3500 stall speed, When driving on the street at slow speeds, should it feel as if the tranny is almost slipping and not fully engaged?
