I would make sure your shift linkage is actually putting the trans into 4th gear. Have someone move the shift lever to each position while you are under the truck (not running of course) and you can hear it click into each position. If it is going into the correct position for 4th, time to take it to a trans shop. Having the TV cable mis-adjusted could have possibly damaged the trans. And you are absolutely sure you have a 4 speed OD trans?
