These threads may be able to help you test- while we could speculate your pressures and other checks will help to diagnose:

Have you put a gage on it to see what the pressures were in each gear, high, low and reverse.

A little more detail would help. Did this happen all of a sudden, did you get it this way?

It may be the linkage. On mine I had to grind out the slot so it would go into low all the time. Still needs to be ground out further. your pressure for 2nd forward and reverse are good.

You need to get it into low forward and check the pressure to confirm. You can unhook the linkage from the handle to see if it goes into low.

Put the range (1,2,3,4) selector in neutral with the brakes on. You will be able to hear when you make direction change and/or a low/high change and see it on the gauge.
