hi.....when you say you 'reset the PCM' how are you doing that? I've just started having this issue on my 06...I've changed every fluid, filter, temp sensor that have anything to do with this issue and i'm still getting the hesitation and then hard shift between 1st and 2nd....but only seems to happen when Rubi's not warmed up. (still testing this warmed up vs. taking off cold thing). I'm not getting any error codes/check engine lights either. so frustrating! thanks in advance!
is this the reset? I've also heard holding the brakes for 30sec while battery unhooked as well.
Disconnect positive
battery cable.
Ground positive cable for 30 seconds.
Reconnect positive cable
Turn ignition key to the "run" position (do not start engine)
Turn headlights on.
Turn headlights off.
Turn ignition off.
Computer is now reset.
