On my way to work, I would think I would have noticed it before the main road but the speedometer wasn't working. The odometer was working though WTF? I noticed when I was going appx 50ish the speedometer was up to about 10 MPH. Getting signal but sluggish. Hoping it was due to the cold even though I ran the car and heat 15 minutes before I left. It was about 26 F and the car was warm inside, engine temp half way so fully warm. Stopped off and shut down and restarted no deals. 2500 rpm = 45 mph (3:64 gears).

After work everything was fine again. Never experienced this before so figured I would post just for my own reference as I usually do lol.
