I am experiencing what i think is the TC going in and out of lock up. This occurs randomly and anywhere from 40 at initial shift into OD and cruising at 70+ on the interstate in cruise control. The tach jumps approximately 250 for anywhere from 1 second to 20 seconds with no increase in speed. I have taken the truck to a friend (master mechanic) and he said it could be due to brake switch position. he adjusted the switch with no favorable result. He said that the position of the switch in relation to the steering column does not allow for adequate movement to remove the gap between switch and pedal. The next step that he recommended was a new switch that could be modified to close the gap. Anyone have any thoughts or suggestions to try before I buy a new switch?
