Last week I had level 10 install trans, 2,200 stall converter, and valve body. They piggybacked hp tuners trans portion on top of the bullydog tune, now the truck short shifts at 5,100 into 2nd.
Prior to the trans work/HP tuners it always shifted around 5,800 or so.
All other gears shift at redline (about 6k), the 5,100 shift is the same regardless of load (pulling 1,600# trailer), I am manually able to keep the truck in 1st until redline.
I was told by bully dog that the shift points are not adjustable in their programmer and that parameters had to of been changed with the hp tuners, just trying to see what options I have in fixing this.
