Sorry, you lose. Read your Owners Manual.My I4 2007 Camry automatically downshifts (5to4 or 4to3) when braking downhill. I think they did this to aid in braking, but this will wear the clutches out prematurely. Is there a way to defeat this? I would much rather replace pad and rotors than rebuild the trans. If I want to downshift going downhill, I will do it myself.
