The overdrive light flashing means the TCM (transmission control module) has detected a problem and is setting a trouble code(s). Your symptom of being sluggish in forward gears suggests the module has shut down the operation of the shift solenoids and your truck is in failsafe mode, so you are starting out in third gear. You need to pull the codes from the TCM and have the problem diagnosed.
