Hello and welcome to JustAnswer! An electrical issue should never prevent a transmission from engaging, but having water in the TCM isn't a normal failure either. P0730 sets when the TCM has identified a gear ratio error - it knows the trans is slipping and has set a code. The problem is most likely a mechanical or hydraulic failure in the trans, but if there was water in the TCM I would recommend replacing it first.

Today I noticed that I didn't even need the key in the ignition and the gear shifter moves without my foot on the break
Expert:  sprinkles08 replied 2 years ago.
That would be a failure of the ignition and brake interlock and should be unrelated to the trans problem.
