|
Always wear protective gloves. Incorrect connection may cause damage to the transmission since the fluid filter incorporates a non-return valve which will prevent the fluid from circulating in the transmission. Furthermore, the fluid cooler will not be cleaned if the equipment is not connected correctly.

Oil the sealing surface of the adapter plate with DEXRON II and fit a new fluid filter.
