All the codes seems to be related and I would sugggest starting with checks to the soenoid harness connectors. Look out for contaminations or water entry damages that usually results in oxidations at terminals and pins.

Have a trasn guy look at it and make sure your fluid is fulll. It could be solenoids inside trans or a poor electrical connection or an internal trans problem.
