lol I checked this thread first so I was a bit lost..."I don't see a reply here..." ;) But yes that will be checked next...I'm working from easiest, to cheapest, to hardest, to most expensive "things to check"...and that day I couldn't get to the plug.
Updates:
I've gone ahead and ordered the shop repair manual, wiring diagrams, and transmission repair manual from Lexus (well ebay really) so until they get them in and familiarize myself with the finer workings I won't be able to do more than throw wrenches/parts at the problem, I hate doing that, I always prefer a more organized, logical approach...THEN go to the abstract hitting with a hammer crying like a baby while rocking on the ground in the fetal position wimpering "this can't be happening...this can't be happening"...I try to do that last, I get fewer odd looks if I don't jump to that last step of the diagnostic process.
more things to check...hopefully I'll figure it out and help some other poor sap ;)
