The kit contains uniquely designed parts to prevent the loss of pressures within the main line, EPC, solenoid feed and converter circuits. This kit also includes modifications that provide firmer shifts, improves intermediate servo and direct clutch pressure, and improves TCC apply. The kit also seals multiple circuits known to suffer from end plug leakage or poor checkball sealing. No special tools are required for installing these parts.The Zip Kit quick guide provides clear and easy instructions on one sheet to get the unit sealed up and back on the road fast.
