Notice the erosion of the friction material that is always present. This condition not only causes slipping but also unusual “buzzing sounds” from the converter area

Let’s take a short trip back in time earlier this year to Bohemia, New York, the home of Pro-Torque, Ltd. Joe Rivera and family hosted a hands-on open house for the TCRA members and nonmembers enjoyment. One of the important displays highlighted the rebuilding of the ZF5HP. Considered to be unrebuildable by many, it is true with proper care that this converter can be easily and successfully rebuilt.

Many companies steer away from this infamous unit due to difficulties encountered during removal of the captive clutch. Under NO circumstances should this step be avoided.

There are three basic types of clutch retention: crimped retainer, friction welded and complete welded versions. Recently Joe Rivera has explored the rebuilding possibilities of this unit in great lengths. We all owe Rivera a great “Thank You” for sharing his knowledge with members. Rivera has also written a complete technical bulletin regarding this topic and can be found on upcoming web pages. It is here that you also find, in detail, the proper dimensions and procedures to successfully rebuild this converter.
