Maybe i could get some help on this. I was having a problem with the torque converter lock/unlock so i replaced the alternator and both battery's since the battery's were getting old and the problem is gone. i drove it for a day then check engine light came on. i hooked up to it and it saying code P0720 output speed sensor.I was have intermittent issues before this for about a year with the abs light and brake light coming on and off and it has come on twice in the last day now. could this be the PCM going or gone. Any advise would be great.
