I have a 2000 RX300 with 110k miles.
I've started getting an intermittent P0768 code. The check engine light will come on and then next time I start it,it will be off, and stays off for 1-2 weeks.
When I check the code it is always P0768. The transmission appears to shift fine.
I'm taking it to a transmission shop, but thought I'd ask for anyone's experience so I can be ready when the mechanic tells me his findings. Does this sound like a solenoid failure? Loose wire? Transmission?
