Tool Kits:
- ZF8-AFL-TK This tool kit is required for installing the oversized pressure reducing (AFL) valve included in the SK®8HP SHIFT KIT® Valve Body Repair Kit
- ZF8-TCREG-TK This tool kit is optional. We included an optional oversized converter pressure regulator valve in the SK®8HP kit. At this time, half of the bores we’ve seen do not show signs of significant wear and do not require the oversize valve. This tool kit is designed only for those units that do exhibit wear.
