I use LexusLS's photo to note the steps under the hood. 1. Remove this first throttle cable, as it is attached to the transmission. Chase it behind the enginewhile unclipping it from the support clips. 2. Remove the transmission dipstick, and dipstick-tube. There is a bolt that holds the dipstick-tube to the exhaust header on the driver side. I believe it's a 12mm. Unbolt it to free the tube, then pull it up and out.
