umm...i personally wouldnt touch it. my friend does it all the time but it is just unnessecary wear and shit. hahahaha, my friend had a rental because his car was in the body shop and he went down the same hill trying to downshift it into 2nd...he accidently puts it into Reverse and it shuts off the truck's engine and he has to force the brake to the floor since there wasnt any power assitance...

it is normal for it to stick for a couple seconds but what is hella cool about this mod you can do to camry v6's is change a cable that controls the tranny shifting and it will shift way harder which actually saves the transmission because the clutch packs wont have to "engage" it as long.
too bad they dont have it for accords.

just use up your brakes...they are much cheaper.
btw? how many miles on accord?
