The only normal way 1/2 can overlap is if the low/reverse band is stuck on. But it's obviously not because it's overlapping 2/3 also which has nothing to do with the low/reverse band. It almost sounds like its got a loose or cracked valve body that it's applying throttle pressure to the back side of the shuttle valves for the shifts, but that's odd too since it sounds like you have the kickdown lever tied in one position.
Give the board some time, there are some smart guys on here, they may just not check the forum every single day.
Yes lever is tied at 80% range this weekend I was planning to try and move it to 100% and see if that does anything.
