T-0015 Lip Seal Installer and Remover Transmission Tool (2-Piece) for TH400 and Rebuild Work

Lip seals are one of the easiest parts to ruin on a rebuild. Pry an old one out with a screwdriver and you gouge the bore; push a new one in over a sharp shaft shoulder and you shave a sliver off the sealing lip that leaks the day you fill the case. This tool is the trick the factory manuals show for getting around both problems. The thin, high-strength steel wire loop slides in behind a seated seal to catch it and draw it out clean, and on the install side it wraps the fresh seal lip so it rides up over a shaft step or snap-ring groove without ever contacting a cutting edge.

You get two tools with two loop gauges, a finer 0.016 inch and a heavier 0.035 inch, so you can match the wire to the seal you are working. It is the go-to auxiliary tool for TH400 rebuilds and works the same on the lip seals and O-rings throughout most automatic transmissions. Because the loop cradles the seal instead of forcing it, precision seals and O-rings come out and go back in without the cuts and rolled lips that cause slow leaks.

Machined from aluminum with a steel wire loop and an anodized coating, so it shrugs off shop humidity and ATF and keeps its shape job after job. Replaces the Atec T-0015 and Kent-Moore J-26744-A. For the price of a couple of seals, it keeps you from installing a leaker and having to pull the unit back apart.
