DRUM CONVERSION KIT, 4R100, DIRECT 4 CLUTCH DIODE TO 45 ELEMENT SPRAG
Sprag kit for the 2001 4R100 with the diode one-way clutch. Most 2001 4R100 transmissions came with a defective mechanical diode on the direct drum. This kit attaches to the direct drum and allows you to switch to the stronger sprag clutch without the expense of replacing the direct drum. The sprag isn’t included. The diode clutch should always be switched on any 2001 4R100 rebuild.
