I would suggest finding the source of the leak and repairing that first, refill and test, if you can find the leak and need help on how to repair it post back here and we will help you out.

First and foremost the leak needs to be repaired. However, we need to then monitor the pressure in the unit to ensure that when the fluid is at the proper level the pump is able to supply the needed pressure. There could be other issues but the fluid leak needs to be addressed first. Then take a look at the attachment and see the test port. If you do not have a gauge then simply locate a parts stores that rent tools and they will be able to provide one.

Once the leak is fixed and the pressure is checked then we need to retest.

If you need assistance in locating the leak, simply put the vehicle on jack stands and fill the transmission and then put it in gear and verify where it is coming from.

Please reach out with what you find and we can go from there.
