2006 lexus is350 transmission problem
I been struggling for months on a repeating cycle of pain and money hole, someone please help!
My first original transmission went bad one day I swapped it and the new one got bad too its always 3rd gear, I replaced it 3 more times with 3 new transmissions and still same exact problem, I changed ecu 3 time and reprogrammed them to the car, checked all the harnesses to engine and transmission still same problem.. ecu been tested on different is350 and works perfectly fine. I have no hope left in this car to fix any more 4 transmissions later and a lot of money down the drain still at square one. if someone knows anything please don't be shy and reply to me.
Thank you
