recently i have had a problem with my truck when it is hot outside and ive been driving for awhile it jerks during takeoff usually thought the first 2 gears im curious what could be causing this once the truck cools down it doesn't do it im hoping i can discover what the problem is before it becomes more constant . I have checked the fluid its still red and full and the oil was just recently changed
