Hi, my name is Marty.

The problem is typically caused by low governor pressure. This is a common symptom as the transmission wears. You could try having the transmission flushed and see if it improves. You could also have the valve body removed and cleaned and have the filter replaced. If none of this helps you will need to have the transmission rebuilt.

Let me know if you have any questions.
