I have an 04 ls v8. 88k miles. Its the 5 speed auto with the sport override (where you choose gear) (if that even matters) anyways, iv finally got the car in working order and started driving it. The trans is a disaster. It has failsafed twice and gone into “E” mode and refused to change gear. Turning the cat off fixes it untill it fails again. Iv had successfully driven it on a 20 mile trip another day and nothing went wrong. Its also had extremely aggressive shifts and not wanting to shift at intended time. At low revs its smooth enough but anything above 3,800 it jerks and throws the car around. Yes the battery was disconnected on and off for a few months and probably screwed the computer up based on the slim information on this issues i could find.
Iv put together a few fixes…
1. Fluid flush (was planning on it even if the car shifted fine)
2. Computer “flash” or replacement.
3. Solenoid replacements.
If anyone has specific details or information on this issue and potentially things too look for and fixes that would be great!
