Yes that what this is , At about 15 MPH when the truck trys to shift but dont then repeats then finaly goes into the next gear
Reset your APPS first then if its still an issue isolate the APPS wires running to the ECM
Once you clear this up its sweet !
Now to take care of 2 other issues 1. Dieing going into gear and 2. OD Lock Up
