Lexus ES Transmission Problem

Hi, I have a 2003 Lexus ES with a gasoline engine. The automatic transmission seems to have a problem in park. The engine won't start, the check engine light is on, and the gearbox shifts uncleanly. An error is stored in the error memory. Any ideas?

A 2003 Lexus ES is experiencing transmission issues, including difficulty starting in park, a check engine light, and unclean gear shifts. The problem may be due to a faulty transmission sensor or a defective control unit. It is advised to consult a mechanic for proper diagnosis and repair, as the issue was resolved by replacing the defective control unit.

Sounds familiar. I had similar transmission issues with my ES. Does it feel like it's slipping between gears sometimes? Could be a faulty transmission sensor. Check your shift lock and park brake too.

Thanks for the quick reply. Slipping is a good way to describe it. Where exactly is the transmission sensor located? Is it something I can check myself or do I need special tools?

I wouldn't recommend messing with it yourself unless you know what you're doing. In my case, the affected control unit was defective, so better go to the workshop.

Okay, thanks for the advice. I took it to a mechanic. The control unit was indeed defective, and the repair cost me around 1000€. Problem solved.
