Has anybody had any luck with shift improver my 2000 4x4 has one hard shift wondering if any additives have worked well for anyone

 

My Edge Evo on "tranny" setting helped with the hard shifting. It lowers your shifting RPM so it minimizes that thug once who next to higher gear. Not punching the gas pedal all the time during traffic lights help a lot too with the side effect of improved gas mileage.

 

i think your screwed, getting a 5 speed manual tranny for that beast!!
