Default Help!!! Limp mode 42re P0748

Hi all and what a great forum! I have an 03 WJ Laredo 4.0 4wd. I had the transmission go into limp mode, p0748. My transmission guy replaced the solenoid and transducer, with mopar parts.I have been fine up until about a week ago. I did a reset of the computer and it takes no time to pop up again. I had heard that an o2 sensor failure can also throw this code due to a shared ground. Could the o2 relay also cause this issue? I am at a loss here! Putting new 02 sensors in to test the theory. If anyone has had this issue please let me know how it was resolved! Thanks in advance!
