Do Shift Kits make a transmission shift hard?

No they do not.

TransGo Shift Kit® valve body repair kits are engineered to correct rough shifts and to correct other shift malfunctions that can reduce transmission longevity and durability.

You may notice a more progressive shift feel after a shift kit has been installed. Progressive, meaning the shift becomes firmer in relation to throttle as it should for maximum durability.  Shift feel will also depend on a wide number of other factors such as;

  • Vehicle weight
  • Tire diameter
  • Differential ratio
  • Engine torque
  • Converter stall speed
