Can anyone tell me a DIY way to do a shift kit on my automatic 1994 Toyota Soarer? My goal is for my car to shift smoother instead of sputtering when I go full throttle

 

You may have other issues if your are sputtering when you go wot. I've never heard of an auto tranny causing a car to sputter.

 

are you looking for firmer and harder shifts..like to chirp the tires? and to improve upon your track time?

this might be what your looking for

 

yea iim trying 2 achieve exactly wat your saying. IM trying to get my track time down and i feel i should get this sorted out before i do the single turbo swap because in my opinion there would be no point in building up power if im not shifting alot better
