[AT] OT - Pickup Transmission Question

[CBear81438 at aol.com]

Sounds like vehicle speed sensor or the woring harness may be loose, or  
broken wire..  I hate these electronics systems after they get some age on  them.  
 I had a shifting problem in the overdrive with my F 350 95  model.  I had 
changed the tail loghts to LED and the cab mounted brake  light was burned out.  
The comuter runs a continuity check on the brake  lights and there4 has to be 
one bulb with a filament in the system for the shift  sequence to work.    
$2.00 at the dealer and it worked.....
