My 2009 RX350 has started hesitating when I give it gas. Not sure what to do but know if I take it to the dealer they will find $1000 worth if repair regardless.ideas?

 

Is it the engine hesitating or the auto trans

 

I think it's the transmission. feels like it is not shifting

 

How many miles on the trans oil, ... color red or brown.... does the oil smell burnt/stink...new trans filter and oil if its not too late
re learn the trans throttle input.... turn ign key on push throttle pedal all the way down slow... hold it down for one minute.... let it up slow.... start engine.. how does the trans shift now
