Tweaked with my 4L80e tune, now won't downshift from OD/4th into 3rd while coasting..
Hey guys, I have HP Tuners and know enough to get into trouble. Last week I was messing with some shift settings, mostly lockup for towing on my 2003 Silverado with a 4L80e swap. I noticed yesterday that when I now manually move the shifter from 4th to 3rd while coasting downhill (mostly for engine braking reasons) it won't actually downshift into 3rd. If I am cruising with the throttle applied and I move the shifter into 3rd from 4th it will downshift. I have compared previous tunes, but I am at a loss to what I changed.
I will gladly email my tune to anyone who wants to see the actual settings.
Thanks!!

I used the Blue Cat software to setup my truck (4L60E), and my car (4L80E).
Both shift great, up or down.
