if you have a shift kit on a 4speed auto does that mean you can manually shift between 1,2,3 and 4 ??? if soo what are some approx. prices, and is it worth doing it to an N/A also are there any places on the net that i can check out some exhausts, mufflers and extractors?? thanks for any help

You can't really get a shift kit for the Jatco auto. At least thats what i've found out in my experience. Mine has parts from a Turbo 700 (VS commo etc.) with thicker clutch plates an adjustable modulator, stronger springs and modified valve body. I don't know the exact specs, i haven't even paid for it yet. But it works! Its not really worth doing unless you need to, that was the only reason i had mine done. It doesn't change the way you manually shift, The power button on the shifter locks out the overdrive. So shift through the gears with the button on, when you want to change to fourth, push the button back to the off position. Do a search for Genie, Walker, Lukey and Pace maker for exhausts.
