My brother in law called me the other day saying his 03 was shifting strang when cold. He said it wouldn't shift till almost redline then shifts real hard. Threw codes P0700 and U2105. He has the Edge with attitude but says he has kept it on lvl 1. Truck has about 135000 miles on it. Any thought on the codes? I told him the first thing to do is change the spin on filter, but I am worried he just got the DEATH code for his tranny.
