The above transpired after a boatload of mostly unnecessary mechanical repairs perpetrated by an independent shop under the guise of being "required" repairs in order to pass PA State Inspection.
None of these repairs involved the transmission.
[EDIT] Ran fine for 1 week, then began overheating, Took back to same shop.
Replaced:
Thermostat, Thermostat seal, Thermostat Housing
A few days later, owner repeatedly waking up to a dead battery every day. [\EDIT] Car can be jump-started, but shifts hard and now MIL is on. May be other lights on; I have not yet seen the vehicle.
-----------------------
Stored codes are
P0734 Gear 4 (4GR) Incorrect Gear Ratio)
P0735 Gear 5 (5GR) Incorrect Gear Ratio)
P0775 Pressure Control Solenoid "B"
P0795 Pressure Control Solenoid "C"
---------------------
Attempts were made to find the source of the parasitic drain via fuse pulling but those efforts were unsuccessful.
Someone suggested security system might be causing no-start condition. New key cut at dealer. No change.
----------------
Battery was changed to ensure it was not the cause of the no-start.
No change in behavior.
----------
ALL of this information was relayed to me; I am walking into this as a favor. I have not even seen the vehicle yet.
--------
Transmission (5R55S) was rebuilt in 2012; reasons yet unknown, mileage yet unknown.
-------
Electrical
I suspect the Zener diode on the output of the alternator has broken down and the battery V current is flowing back through the alt to ground overnight, enough to droop the battery such that it cannot start the vehicle. I've instructed the owner to go to Autozone or similar and request a free complete charging system test to see if it picks up an alternator issue.
[EDIT] There is also the much simpler explanation that there is a defective switch that is not turning off a light as it should (glovebox) and that is draining the battery, but I would have thought that would have been uncovered in the fuse pulling exercise. [\EDIT]
--------
Codes
I have seen certain combinations of codes thrown on Saturns (I am a mod on a Saturn forum) that point to A but as a group indicate B, or in some cases point to C which seemingly has nothing to do with the codes that were thrown.
Trannys are by far my weak suit, so your patience is appreciated.
