Re: AL480E Question
I would either call up the dealer or take it in cause there is an update for the pcm for that issue. Mine was acting up every so often where it would start out in second gear from a stop. If my truck was an 03 or newer there is an update for the programming to adress that specific issue but i was sol although the still updated the pcm for general driveability issues.
