I was driving yesterday at 35 mph, all of a sudden RPM went straight to 0. I noticed through out the day the RPM would fluctuate. When the RPM dropped everything locked up but I still had power. And the vehicle is an automatic. What might cause this?

  • Welcome to Motor Vehicle Maintenance & Repair! Is the Check Engine Light (CEL) on? If so, have you had the codes read? Really, your question doesn't give us much to go on, so we'll need a lot better information as to what's going on to give you a coherent answer. – Pᴀᴜʟsᴛᴇʀ2 Mar 4 at 14:43
  • Also, what does "everything locked up" mean? Needs more detail. – JPhi1618 Mar 4 at 17:35
