No they do not. TransGo SHIFT KIT® valve body repair kits are engineered to correct rough shifts and other malfunctions that can reduce transmission longevity and durability. You may notice a more ‘progressive’ shift feel after a TransGo 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
