Transmission Fault with no other symptoms - p2727 & p0730

Just bought a 2007 supercharged at a big discount due to a "Transmission Fault" warning that comes on a few seconds after startup and then goes away a few seconds later. Drove it home and had no issues at all and no other messages. I tried all driving conditions (hard acceleration, heavy load, hot, cold, etc.) Codes p2727 and p0730. Any idea what this could be? It has 114k miles.

Don't know how helpful this is, but AllData shows:

Electronic Automatic Transmission Gear Monitor.

P0730 - Symptom gear monitor fault: Plausibility fault

Possible causes:

1. Gearbox mechanical fault.
2. CAN bus.

	1.	Gearbox mechanical fault.
		No detail available for this fault
	2.	CAN bus.
		FAULT:

• CAN bus.

CHECK THE FOLLOWING:

• Integrity of all CAN Bus connections.
• Look for similar faults in other ECUs on the CAN Bus.
• Look for faults in the originating ECU (if applicable), including intermittent supplies/ground faults.

Refer to the CAN Bus wiring diagram.

AND


Electronic Automatic Transmission Stall Speed Fault.

P0730 - Stall speed fault: Plausibility fault

Possible causes:

1. Transmission Damage (Defective Clutch).

	1.	Transmission Damage (Defective Clutch).

The P2727 comes up with Pressure Control Solenoid, again not sure how helpful this is:

Update: I took it to a local transmission shop and he found a few more codes and said it needs a rebuild.
