If i pull the lever into 2nd at about 70km/hr, the truck should rev right up to 2500+/- rpm and hold back. i even flip my exhaust brake on on the big hills and you can feel the engine grab the wheels and rev up then let go all in about 3-4 seconds. it will do that for about 15 seconds then stop. tranny dosent seem to heat up, no codes, and once its in OD everything is fine again. guess next step it a dealer computer...
