Hi, I've got a 2000 Quest. When going up hills, the engine stays in low gear and moves really slow. If I press on the gas, the engine jumps into high gear, and whines, but the van goes faster, then falls back into low gear. I've broken a couple of engine mounts due to this all of a sudden, violent acceleration. It's like it jumps into passing gear. Basically, the van doesn't shift into higher gears when under load, unless I smash the gas pedal. On the freeweay, it's fine, though, and goes through all the gears automatically. I've been told this is probably a computer problem. Does this mean an 'engine' computer, or a 'transmission' computer problem? Are both/either easily replaceable by the do-it-yourselfer? Does either/both have to be programmed by the dealer. Thanks in advance.
