Forgot to add that this goes away when you let off power. Now I am really confused. I also posted this on JustAnswer.com and got response from Lexus experts that totally contradict each other. One says Type T-IV no exceptions which I paid for the answer and the other says this model year took Dextron Type III and type T-IV was for later years. Who to believe?

I have a 2000 LX 470 with 70K on the odometer. I recently had the trans fluid changed at an oil change facility because it is a long ways to a dealership and one third of the cost. They used Multi Trans Fluid to refill. I have noticed a low noise almost like a quiet but discernable growling noise when car shifts into overdrive. Still shifts smoothly though. I have had responses of wrong tranny fluid must use only Toyota T IV. Called oil facility and they state nonsense their oil companies fluid exceeds manufacturers specs and has been used for years with no problem. Took it to Lexus dealership and of course it took 2 seconds to get a diagnosis of internal transmission problems with overdrive unit and fix is to R&R the transmission. Nonsense as they want over $3 Grand to do that. Click the overdrive button off and noise goes away. Almost sounds like something is vibrating. Any ideas?
