Revisiting the Captive Clutch

Joe Rivera proved that the ZF 5HP19/24 converter with captive clutch is rebuildable (see “Rebuilding the Unrebuildable,” Transmission Digest, December 2005). Many converter shops are now trying to build this unit, and the number of rebuilding questions continues to increase. A recent rise in issues related to lockup performance after rebuild has prompted a closer look at this unit. The same fear factor that prevented many shops from trying to rebuild this unit in the first place is now causing some of the braver rebuilders to have second thoughts.
