You are probably low on fluid.
Behind the rear seat is your motor/pump/reservoir combination.
With the top DOWN, fill the reservoir to overflowing with ATF.
Cycle the system a few times and repeat.
Do this till the reservoir will take no more fluid.
Check the lines and cylinders for leaks. The fluid must be going somewhere.
If you replace any lines or cylinders, always do them in pairs.
