Working on a 700R4, 4L60E, 4L60, or 4L70E transmission? This pump tool kit makes installing turbine shaft seals and pump stator rings way easier – and saves you from damaging parts during the job. The kit includes a ring expander and re-sizer for Teflon seals, plus a bushing sizer rotor aligner to get pump bushings and rotors lined up perfectly. Made from quality steel and PVC, it's sturdy yet light enough to handle in tight spots. The step-by-step process is simple: lube the expander, slide the ring on, walk it into the groove, then use the sizer to collapse and seat the seal properly. It prevents leaks, misalignment, and seal deformation, which means fewer comebacks and smoother transmission operation. Whether you're a pro builder, a DIY mechanic, or a shop tech, this tool saves time and frustration. Compatible with THM700-R4 (MD8), 4L60, 4L60E, and 4L70E pumps. Compact design fits in your toolbox without taking up much space. Stop fighting with seals by hand – get the right tool for a clean, professional install every time.
