Could a P0753 Shift Solenoid A Electrical code cause my battery to drain?

Question

We charge the battery overnight. Put the battery in the car and the battery dies within 30 minutes. We replaced the alternator, starter and battery already. (all needed to be replaced) The funny thing also is that if we disconnect the battery while the car is running, the car dies. This, to me, means the alternator is not working but we had it tested at our local O'Reily's and they said it is functioning properly and the battery holds a charge.

HI there

If the solenoid is shorted out, it's possible it could be draining the battery. You will need to test the solenoid, or you could try disconnecting the transmission harness and see if the battery still drains over night. Also, watch for any under hood lights or trunk lights as possible causes.
