Hi,
Finally I got an scanner that read ABS codes, as they were the most frequent happening in my case. I got it yesterday and this morning I give it a try. Yes it worked and identify my faulty rear sensor at the differential. No new news there for me.

But in going through the motions of learning how to operate a new tool I got this code for the TCM (P0884 "Power-up at speed") That code is not in my list that I got from viewtopic.php?t=11386 from oldnavy, and my other scanner did not read it.

I do not feel any malfunctioning of the transmission except for some erratic shifting at around 45 to 50 mph while under light acceleration, like getting up to speed at an access ramp for a highway after a short stop, and after being on the highway for three or four hours. This happened two or three time on the last 12 to 14 months. And yes I do have some occational shudder from the TC that I know how to avoid. The transmission is new (factory rebuilt) installed in Novenber 2017, with about 35K miles mostly highway.

Have any body an idea of what this code P0884 is?

Thanks,
