Reversing valve or txv
Diagnosing a Trane 5ton packaged heat pump Suction pressure will not go above 60. Reversing valve very sluggish furring changeover. Any thoughts
With a 5-Ton heat pump there may not be enough airflow heatload to load the coil & suction pressure above 60-psig.

There are a number of components in the refrigerant system; besides the TXV & reversing valve; that need checking.
The systems airflow should be checked first, then subcooling & superheat should be checked.
Also, check the temperature rise off the outdoor unit & the temp-drop indoors between Return air & supply air, along with the % of relative humidity; the indoor humidity level is critical to know when trouble shooting a system.
All the system pressures need to be checked...
Some indicators will begin to show-up.
