Can I press the brakes while shifting from d to d3 while going down a steep mountain?
I have a 2003 4runner with an automatic transmission. I am heading over
some steep mountains with a uhaul trailer and was advised to downshift to d3
so i don't burn out my brakes. I've never downshifted before so wondering if i
can shift from d to d3 while braking? And also goig from d3 to d while hitting
the accelerator pedal.
