I have a 2000 Es300 with 141K miles. Runs good, nice car, etc.
In the chicago winters, I start the car from cold, and until it warms up, the trans has trouble shifting up.
In the neighborhood (driving slow), it gets up to right around 30 mph, and the engine is revving at 2750 rpm.
If the car were warm, it would shift, but because it's cold, it holds onto that gear.
If I go faster - up to about 3000 rpm, the car will then shift.
When I leave work, within several hundred feet, I'm on a fast road.
Because I'm on it a bit, the car keeps shifting, getting up to alomost 50mph, and about 3000 rpm.
It will not up shift. I've tried pressing it a couple times, but depending on how cold it is,
I'll have to drive another half mile or so, then it will shift up and drive like it normally would.
Once it cools off, it has these issues like clockwork.
I had a 95 camry v6 before this Lexus, and it never had this problem.
What the heck is going on? I've reset the car by disconnecting the battery for a long period of time. still does the same thing - when it's cold.
I THINK during the summer it was OK, but when the temps started cooling off, it would act up.
Does anyone else have this, or more importantly, know what is goin on?
THANKS!
