Chrysler Pacifica throwing code po882

I had a Chevy s10 it did the same thing I was told all of those trucks when the motor gets hot it stays in low gear because it should have a extra fan to cool the motor but it doesn't. but you can install one yourself

it gives a po882 power input signal low

Check the Transmission Relay Switch, located on the Driver side of radiator. Should be attached to the frame of pacifica. Had this issue, replaced the Switch and was good again. Although it did start having issues again, this was related to the driveshaft, having play in the U-Joint. Had to replace entire driveshaft. Good luck
