What could be the problem with my 2008 Ford F150 4.2L for the code P0720? Transmission is Slipping, I put in a new output sensor. Still slipping. I cleared the code. So now I'm waiting for the drive cycle to complete.

Best answer
P0720 Output speed sensor

What the ECM does is look for open, shorts ,grounds and rationality, P0720 will result in harsh shift or abnormal shift, if this is the sensor , P0720 more than likely appears due to a internal mechanical transmission problem.To set the monitor you will need to use a transmission additive such as Lucas. Your acceleration must be light to modearate,
