Shift kits.. do you really need one????

Done right, a shift kit is going to benefit any trans, street, strip, whatever. They made them soft from the factory on purpose to feel smooth, which is what most customers wanted. I put the TF2 in my Chrysler a few year back and the difference was very noticeable - quick shifts with minimal overlap. The trans just feels tighter and more crisp. That car chirps 2nd at WOT, which is pretty impressive for a still mostly all stock 42+ years big, old land barge.
