2010 Camry tranny hunting for gear at low speed
 

This is really weird. 2010 Camry, 4cyl, only 32k on it. While driving slow and soft on the gas, like cruising through the neighborhood, now and then it seems to jump out of gear, hunt around for the right gear roughly, and few seconds later act normally. Not really repeatable. Today it did it and threw a U0100, U0101 code, com error.

Every now and then this car will throw those codes for no reason, and it will have no effect. Usually that would happen if I did not drive it for a few days.

I've checked the TCM connector, reseated it, it's clean.

This was my late mother-in-law's car, not sure what she did to it, but she is probably haunting me through it.

Any ideas?
