I know this is not a place to ask stuff about the LS, but considering the LS430 (2003) has the same transmission (A650E) as the GS and GS people bit more technical :P I thought this would be a better place to post.I bought a LS430 (2003), after totaling my LS460. For the people who have hooked up OBD2/Torque Pro readers, what are the temperatures you get (Highway, summer, winter, idling etc etc) ? Specifically looking for Transmission and Coolant temperatures.
