2003 4l80e has no reverse foreward gears and 4x4 still work perfect.

I have a 2003 gmc 2500hd and I think it has a 4l80e trans. I pulled a heavy load home had to put it in four wheel drive to park it in the field when I put it in reverse to back it up I had no response. No sound, no rpm change nothing. And all foreword gears pull strong. What do u think it could be?

if the forward 4 gears work ''perfect'' , then the problem with reverse is the rear band. Burned up band, broken servo piston are a couple of possible problems
Dont worry how old you are... it is the mileage on your body that adds up.
