This stopped the front pump seal leak on my 2005 Trailblazer

To use this sleeve on a torque converter, the supplied tool isn't long enough. However a piece of PVC pipe can work. (normally this is used on a harmonic balancer) Just replacing the seal for the torque converter often only lasts a couple of months, due to the shaft wear, a reconditioned torque converter and or the fact the after market seals are often not tight enough to the shaft. Pulling a 4WD 4L60-E automatic transmission is a lot of work, and this sleeve kit insures a permanent repair. I highly recommend it, along with a new seal. The repair sleeve manufacturer has a U-Tube video showing exactly how to install it, worth the watch. Use a caliper to measure as instructed.
