Hello guys, so hopefully, someone can benefit from my experience, I was finally able to get the GT1 working.....OBD was showing p1748, transmission module self test. GT1 reads, or looks like either 0F (zero F), or OF ( letter "O" F) and it says PRESSURE ACTUATOR EDS, TOTAL CURRENT.
Does that mean anything to anybody??? I also cleared codes 31 and 22, but the persisten is the 0F....
as far as the GT1, man, I was ready to shoot something, I said to myself, this is the last time, then it's going back on ebay....and voila! it worked.....not quite sure how I accomplished it, but it worked!
thanks guys,
