Will it hurt to drive my 2001 4x4 SR5 2.7L up and down these WV mountains without the overdrive?
I can feel it shift without it on the upgrades bot not on the flats. It feels like I'm always in third gear but it does seem to be much easier on the truck overall to leave the overdrive off while driving the mountains. Thanks for your openions and knowledge. Mike
