having problems with my 2001 7.3 shifting from 1st to 2nd and 2nd to 3rd. won’t shift out of first unless it’s up to like 2500. but shift on time but a little hard for every other gear. light is flashing got it scanned. came back with po182,po183,po132. so i changed the solenoid pack. i don’t really know what’s next. maybe thinking it’s getting grounded out or something.
