I was told to check the connections at the transmission control module to
possible correct a shift solenoid E problem.
Comes on now and then. I disconnect the battery and reset the computer and
the lights go off. Sometimes they stay off for a week or two and them other
times maybe a day. I'm tired of constantly resetting the computer to make
the lights go out. The car shifts fine and runs great.
I go through car washes and the bottom of the car is flushed with water as
part of the wash. It  could be a connector problem so I'm willing to look at
that.
Now, where is the TCM located on a 1999 ES300?
I called the dealer and the parts person couldn't find it in 20 minutes and
then put me on hold.
I'll skip them.
