    I'm looking for some information on the dt 12 transmission. Just recently I am hearing the transmission shift.It sounds like gears grinding when it shifts.I thought maybe it was the fluid,but the fluid level was good.
    Does anyone know what I can do to to resolve this issue?

    Thank you

    Those symptoms sound like a bad deal.
