1999 ES300 4-Speed Overdrive with 109K miles.
Owned since new.
Trouble Code P0770
" The PCM Has Dectected a Malfunction in Shift Solenoid "E" "
The "Check Engine" and "Trac" light are on and it has been this way for
months.
I see no difference in the way it drives or runs.
I unhooked the battery and cleared the code and it comes right back in a few
hours or at most a few days.
AutoZone scanned for the code
Now,
What sort of ordeal is it to get this repaired?
Where is the solenoid and where can I get one or what is the best way to go
with this?
The "NAG" lights are just what they are ..., NAG lights.

I forgot to add that when I drive the car cold it stays in 3rd gear until
the engine warms for a couoole of miles and then goes into overdrive.
maybe that helps with diagnosis.

That is normal operation. The system is designed this way to help the
engine warm up more quickly.

The shift solenoid is located in the transmission and should be fairly easy
to check with a volt/ohm meter and change if necessary, once you have
identified which one "E" is. You can get online access to factory service
manuals at techinfo.toyota.com for $10/day and identify the solenoid and its
location. The solenoids should be accessible from the outside of the
transmission case so you don't have to open up the transmission.

The best place to get a replacement solenoid is at a Lexus dealer.
