GM-52095 is a set of three tools that correctly install and compress the five solid Teflon seals on the turbine/input shaft that seal inside the reverse clutch housing. GM-52095-1 is a long, smooth protector tube with an adjustable depth stop rod that covers the shaft and protects the five seals from damage as they slide down the turbine shaft one at a time. DT‑52095‑2 has expandable fingers that snug fit the protector and evenly push the seals down the protector into their respective grooves on the turbine shaft without over-expanding the seals. GM-52095-3 features a tapered ID that gradually compresses the seals to the correct size OD, allowing them to slide smoothly inside the front support assembly ID without being nicked, cut, or twisted out of the groove.
