The P0701 is a transmission "Range/Performance" Code. This means there's is transmission sensors sending faulty data to the PCM. The input shaft sensor and output sensor are out of sync becasue the transmission is starting to slip.
It sounds like the transmission is going out which sets this code.
Please let us know happens so it will help others.
Best, Ken
