TransGo Performance TH200/700/4L60-70E Unbreakable Pump Rings for engines that rev above 5400 RPM 700 PKH

Description:

We know the sick feeling in your gut and the pain in the brain when a job comes back with broken rings. Most of the time it takes the trans and the converter along with the pump, and the customer is positive it’s all your fault. The rings in this kit are not cast iron or compressed metal. They are not brittle. They are tough, high carbon, heat treated annealed steel precision-ground for thickness and outside diameter. Because they are slightly larger and stiffer, pump efficiency is increased. You will notice higher pressure at hot idle. The kit also includes a priming spring that corrects the high rev drop that occurs above 5500 RPM.
