Hi guys looking for a simple answer. Garage kept my Evo this winter and wanted to drive it now did all normal checks and found the pump in rear trunk reading just below minimum. I’ve drove it a couple times in the winter and had no issues with flashing lights or codes popping but they were very short drives around neighborhood. I’m planning to just add the ATF SP3 fluid to the reservoir to max again but is this okay? I know the system is pressurized so wasn’t sure if okay. Then I would wait and see what happens to the level after but I’m guessing something’s wrong for it be low. I’m at 120K miles. Fluid never changed or touched.

 

You should only check the level after the car has sat for 90min or longer after driving. So If it's been sitting and is low, add fluid.
