Hi, my name is ***** ***** you for your question.
Sorry for delay
The trans shifts off of throttle position and engine load so if TPS is showing low % it will do what its doing.
It will also shift like that if engine is not producing any power so check all basics like fuel system and CAC for leaks.
Its also a good idea to check engine breather, if engine can't breath it will have same effect.
