Pour fluid as fast as necessary to prevent reservoir from going dry.

Stop engine after about three quarts have been dumped.

Reconnect return hose.

Fill reservoir to required level.

Install cap.

Toss out old transmission fluid (or burn it in the tank).

Done.


I'm still unsure of why you want to switch it to PS fluid? If the switch was made prior to the pump seals leaking, you might have an argument. But, the pump seals need to be done in any case. The current ATF is pristine clean due to the leak.



FWIW, I do not believe anyone can state, for certainty, that the two fluids are definitely compatible with each other over a long time interval. Personally, I would not mix them.
