to me, its like riding a bicycle/swimming. u may lose touch, but
u will not forget how to drive a manual.
when i got into my friend's manual, i instinctly put my left on the
clutch and right on the accelerator. the changing of gears came
like they should, though i would want to be better at getting the
biting point and such.
and same as u , i have been driving an AT vehicle for 1.5 years
too
