"ncludes the popular Power Shift Controller to give you the ability to select between four different transmission settings of shift firmness. Ranges from Stock, Stage 1, Stage 2 and Race." This sounds great and its for e4od witch my truck has. It is only 130$ so do you all think it will really work? Work as in firming up shifts and what not? JET Power Shift Kit - JEGS check it out and tell me what you think, im just hoping it isnt a waste like the throttle body spacers they make. Thanks again guys

 

IMO you are much better off spending the extra $$$ and going with a machanical shift kit. I have a Factory Tech Accumulator on my 4R100 to firm up the shifts. Firming up the shifts electronically is not the best way to do it and is harder on the pump in the trans and can lead to ATF starvation in parts of the tranny when the firmness is ramped up with the tuner. I still use my tuner with my accumulator, I just leave the shift firmness stock.
