Why is my speedometer working intermittently when my car warms up?
Ive been trying to figure out this problem for a while. My speedometer works, but only works until my car warms up. It zeros out and the odometer is blank. Its making my transmission shift erratically and eating gas. I have replaced the speed sensor located on the top of the transmission and looked at the connector and connector wires. They all looked fine. Other than a little bit of oil coming out of the sensor. Maybe transmission oil? Around the sensor was dry and I seen nothing that would be dripping on it. But its still doing the same thing. Nothing changed. There is no other problem with the dash lights everything else is working fine. On colder days it works longer. On warmer days I will start her up and have nothing. Sometimes it will kick on randomly while I'm traveling at high speed. I am a female trying to learn how to work on cars. Please try and stray away from acronyms I would appreciate it. Or help explain what they mean?
