Awhile ago I began to get a 3-5 shift flare and flashing tow haul light, I cleared codes and kept driving, I returned my sct to stock tune and been driving fine for couple months now then today I get in truck to leave for work and no reverse. Then when I shift into drive to go I get flashing tow haul and cel. Codes come up p2703 and p0766. I drove down road and it wouldn't shift into OD or lock converter. I've cleared codes but soon as I start it up and put it in drive the tow haul starts to flash.

Fluid looks good doesn't smell burnt at, has maybe 7000 miles on motorcraft lv fluid.

This happened to me after I stuffed my built motor in last spring in my 08.

It sounds like either you burned up a clutch pack or a solenoid has gone bad.
