Replying to: backy (Jan 21, 2009 2:31 pm) I just told them that my 1-2 shifts were harsh and that I heard there was a service bulletin about it. The updated the firmware on the computer controlling the tranny and so far I am pleased. I no longer have to get off the gas as I feel a shiftpoint coming.
