Got the paperwork back from the dealer today regarding the issue I had which resulted in the transmission getting replaced at 2600 miles.

The notes have all of the various seals, gaskets, bolts, washers, etc. that were replaced but I'll skip listing all that out. The main items are:

"Caused by: Checked for DTCS found P1AEE, P1AEF. Called TAC after running test. Email freeze frame data to Volt engineer. They instructed tech to replace transmission. 1 & 2 drive motors overcharging."

"Replaced transmission and programmed PIM, reprogrammed HPCM and BECM, and immobilizer. Cleared DTCS, bled cooling system and fill with trans fluid. After replacing transmission and programming PIM vehicle would not start. Request OLH to program HPCM2, BECM, and diag no start condition."

That's a lot of proprietary jargon, but thanks for sharing it! I take it, your Volt is still at the dealership?

I wish I knew what "motors overcharging" meant because I've never heard of a motor charging to begin with. Not entirely sure what that jargon is supposed to mean...

The explanation given to me was that the motors were overcharging the battery when in regen mode. Still not sold on this since the car drove fine to the airport and the problem didn't start until I came back, when the car hadn't been moved for over a week. Only problem with charging that I could see possible would be if somehow the charger at the airport was overcharging the batteries.
