This started happening to me after I installed the SRT intake.

Did you have to replace the sensor? Or does it require another fix?

Per the lexus dealer, my lights are due to some sort of transmission issue.

Thanks, but no worries. Certified pre-owned with 3 year/100K warranty FTW.

I think that would just if the CEL came on. I would recheck the wiring on the ECU for the SRT

What? This is some terrible advice

I mean, it's not gonna hurt to do that, but c'mon man. If it were that simple I/we could have figured it out without posting.

The same lights came on last week in my GS400. Did you figure out the issue? I hate to bring it over to the dealership and pay the big bucks yet. My preferred (inexpensive) mechanic is 160 miles away. I am concerned my car wouldn't make that trip.
