Trying to read powertrain codes on truck i bought. I believe codes have been
erased. How do I get them back. They are not stored. Says everything is ok,
but will only move in reverse.

Any recurring problems will continue to throw new codes. The OBD system wasn't built to monitor transmission problems other than some basic ones, so you may have issues that will never throw a code. A tranny shop can run the transmission on a diagnostic stand however and give you a lot of info.
