Shift solenoid...
You may want to take it to a trans shop and have them read for a deeper look. I have the same problem and I have replaced the solenoid to no avail.
Then I took it to my local dodge dealer and he put a scope on it and he told me it needed a ecm the box that is beside the battery that controls everything. So I bought one and installed it. Still the same problem and 750 code.
