Sprag Kit for the 2001 4R100 with the Diode One-Way Clutch. (WITHOUT DRUM)
#100SK. 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. There will be a 10% discount if you buy the K100 Combo Kit. Order this part if your drum is still good.
