The Complete Pump Rotor/Slide Package 13-Vane (#42288B) is a full pump rotor and slide assembly engineered for the 4L40E, 4L60E, 4L65E, 4L70E, 5L40, and 5L50 automatic transmissions. Built around a 13-vane rotor design, this package restores the precise fluid dynamics needed inside the transmission pump, giving technicians and rebuilders a direct-fit solution for pump reconditioning. Anyone searching for a 4L60E pump rotor kit or 13-vane transmission pump package will find this assembly matches OE vane count and configuration for accurate hydraulic performance.
Worn or mismatched rotor and slide components are a common source of low line pressure, delayed shifts, and inconsistent transmission behavior. This package addresses that by supplying a matched rotor and slide set sized to maintain correct hydraulic clearances within the pump body. Installing a complete, correctly paired set rather than mixing individual parts helps ensure the pump generates steady, consistent pressure across the vane pack, which supports smoother shift engagement and reduces the risk of premature pump wear after a rebuild.
This 4L60E/5L40 pump rotor slide package is best suited for transmission rebuilders, shops, and experienced DIY mechanics performing a pump overhaul or full transmission rebuild on any of the listed 4L and 5L transmission families. For anyone sourcing 4L65E or 4L70E pump internals, this complete rotor and slide set offers a straightforward way to bring pump hydraulics back to proper working spec as part of a broader rebuild.
