The B and M AUTOMOTIVE 93-96 GM 4L60E Shift Kit is a precision transmission performance upgrade designed for owners seeking sharper, more responsive gear engagement in fourth-generation Chevrolet and GMC trucks and SUVs. This shift kit addresses the factory 4L60E transmission's soft, delayed shift characteristics by modifying internal valve body hydraulics and spring tensions.
Engineered by B and M Automotive, this shift kit recalibrates the valve body spring pressures to tighten band and clutch pack engagement across all gear transitions. It reduces line pressure delay and sharpens both upshifts and downshifts, resulting in less transmission slip during acceleration. Installation requires removing the transmission pan and valve body, making it suitable for experienced DIY mechanics with basic transmission knowledge.
This upgrade is ideal for stock or lightly modified trucks that tow, off-road, or see highway driving where transmission response matters. The compact kit weighs just 1.1 lbs and fits within the transmission's existing envelope, meaning no custom fabrication or external modifications are necessary.
