Anyone know what kind of fluid does it take and how i can drain it? thanks

Any dextron automatic transmission fluid, non-foaming. PD uses Havoline MD-3. Not sure about draining it.

Trim your engine all the way down and disconnect the ram from the cross member. Retract the ram all the way into the cylinder. This will minimize how much fluid will be in your lines. Break them loose. You wont have much run out at all. Remove pump, motor,and reservior from bracket. (You may have to remove the whole assemble from your motor mounting bracket.) You can unscrew the reservior and drain. If you try and drain it in place, you are probably gonna make a mess.

Thanks guys for the info
