Lexus LFA Transmission Slipping

Hey, I've got a 2010 Lexus LFA with a gasoline engine. Recently, it won't start sometimes, the check engine light is on, and the transmission feels like it's slipping. Error memory says something about the parking position being defective. Mileage is around 199918 km. Could a defective control unit cause this?

A 2010 Lexus LFA is experiencing starting issues, a check engine light, and a slipping transmission, with an error indicating a defective parking position. The problem may be due to a defective control unit or a faulty transmission sensor. It is advised to have a professional workshop diagnose and fix the issue, as it requires specialized tools and expertise.

I had similar transmission issues with my LFA. Not sure about the build year, but the symptoms sound familiar. Does it feel like the gear linkage is loose or the shift lock is engaged when it shouldn't be? It could also be a faulty transmission sensor causing the problem.

The linkage feels fine, nothing obviously loose. Is a transmission sensor something I can check myself, or am I better off taking it to a shop?

Based on what you're saying and my experience, it sounds like the same problem. The transmission sensor requires special tools, better let a shop handle it. I ended up paying around 1000€ to get it fixed. It could be a defective control unit indeed. Don't risk making it worse.

Thanks, that's helpful. I'll book it in with a workshop. I appreciate the advice.
