Just got my truck back from the shop and I was told they dropped the trans to replace the branch tube for the oil system. When I start the truck the light isnt on but as soon as it attempts to shift from 1st to 2nd the light will go on and it will stay in what seems like 5th gear for the remainder of the time driving it. Throwing a P0720 code but until I get around to changing it can it be driven as it is without hurting it? Or should I change it before driving it anymore?
Thanks

That is the output speed sensor -- check to see if they plugged the sensor in all the way, or damaged the wiring
it is the one at the rear of the transmission
