I have a hammer shifter also and I love it. You almost feel like your better that the sticks..
My friend has a stick and from a dig he gets me by a car in a half if I just let the car shift itself. But when I use the Hammer shifter like a stick we are door to door and thats with the stock torque converter.
i love my shifter. i dont race, never really had the oppratunity to so i dont manually shift it. i sometimes manually shift it while driving from stop sign to stop sign.
i love the feel when i shift it. its hard to explain. especially knowing i cant overshift it or put it in neutral by accident.
i got the converter through a group purchase with stangnet member, gcomfx.com. the converter, and 2 shiftkits came out to around $820 canadian i beleive. cant remember. it was over a year ago.
