I did see it as a PM so I thought I would share what I said.
"Sorry for the delay, I was busy all day.
Do you have a scan tool?
Does the speedometer work? It has to have a VSS signal to shift. No signal no shift.
A broken or bad band would allow a 1-3 shift. A broken input sprag would not move forward."
To add a broken reaction sun shell would have no reverse.
His reply was no Scanner and its going to the shop for investigation.
