I had the Transmission rebuild a couple years ago and afterward started getting an "INTERMITTENT" grinding noise at low speeds both when starting up and also slowing down. I have taken the vehicle back to the Transmission Shop several times and they say they are unable to duplicate the problem and the transmission inspection shows everything is ok. I had the water pump replaced a couple months ago and he also replaced some gaskets and a "VACUUM SWITCHING VALVE". When I picked up the car the mechanic advised me the "CHECK ENGINE LIGHT and VSC LIGHT" were on. He said his diagnostic showed it needed the "OXYGEN SENSOR - BANK 1 SENSOR 1--HEATER CIRCUIT". The warning lights were not on when I brought the car in and I told him so. He denied doing anything that would have caused the lights to come on. I have not made the repair as I am having a dispute with the mechanic however I have noticced the grinding noise is no longer there but after driving a couple miles and warming up" the transmission is sluggish when shifting gears ". This leads me to believe the grinding noise involves the "VEHICLE SKID CONTROL" system. Any suggestions will be greatly appreciated? I have not gone and will not go to the Lexus Dealer and that is a whole other story.
have the same problem?
