I am trying to use the tire gear wizard on my 98 k1500. The tire size is 32.8 and the gears are 4.11's. When I confirm this change it maxes out my transmission shift tables to 256mph and causes the truck not to stay in first.
What am I doing wrong? I would try to manually change the VSSppm but I am pretty new at this and don't want to hurt anything.
This truck is not 411 swapped. Tune is attached
Thank you.
