2003 f150 supercrew 4x4.The overdrive does not disengauge.How do you fix the wire to switch?

 

Welcome to the site..

Did you check the fuse in the Central Junction Fuse box? #29/5amp.. You can also pop the cap on the shift lever and remove the TCS/OD switch and check for power distribution there. Sometimes the OD switch wire/s will wear through or break at the base of the shift lever. Could be the switch itself.. If the wires are worn, most times they can be repaired, or a replacement shifter will come with the TCS harness as part of the assembly. With the switch removed, or the column covers removed, the OD can be cycled ON/Off with a test lead to prove out the system. First check for power distribution...
