Hello,

my daughter's truck has this problem: when driving, the car shifts up fine, then when slowing down, shifts down fine. But once this pattern has happened, if the car then is accelerated, about 50% of the time the transmission won't upshift and will leave the car in a low gear. If she pulls over, turns the car off, then back on, it seems to remedy the problem (for awhile). Also, the O/D light is always saying "off" on the dashboard. Any ideas?

ty!
