4L60E 700R4 4L65E 200-4R Hardened Pump Ring Kit (For Engines Rev Above 5400 RPM)

Product Description

TransGo 700PKH Unbreakable High-Performance Pump Rings for 4L60E, 700R4, 4L65E and 200-4R transmissions in engines that rev above 5400 RPM.

The rings are tough, hardened steel, not brittle cast iron or compressed metal. They are slightly larger and stiffer, which increases pump efficiency and gives higher pressure at hot idle.

Specifications

How it works

Broken pump rings often take out the transmission and converter along with the pump. These high carbon, heat treated and annealed steel rings are precision-ground for thickness and outside diameter.

The kit also includes a priming spring that corrects the pressure drop above 5500 RPM, which makes max throttle upshifts soft on high revving engines.

Corrects, prevents or reduces pressure regulator buzz or moan (especially hot) and high rev pressure drop.
