Hi all. A few months ago I was driving on the interstate going about 85 and suddenly the dashboard starting losing power, all the lights were blinking and the digital speedometer was spastically changing to every which number. The car would not accelerate at first, then slowly picked up speed and was then was running normally after reaching about 30 mph... but this happened a few times within 5 minutes. I left the car off for about a day and the next day the check engine light was off and the car accelerated like normal. This happened again this week, so I had it looked at by a mechanic and this is the note he gave on the car- "output speed sensor circuit intermittent. Monitored sensors, all reading properly at this time. Recommend replacing output speed sensor."


Has anyone else had a similar problem? The car has a little over 96,000 miles on it. about how much did it run to fix it? (Labor included). He is going to charge me about $630 and I'm not too familiar with cars so I don't know what's reasonable. Thank you.

To replace that speed sensor is a PIA. You have to take the valve body out of the transmission.
See I did all that to mine replaced the speedsensor behind the valve body and put it all back together. Drove perfect for a little bit. And same light and instant limp mode again. It's fine if it's cold but after it warms up it jerks on gear and doesn't act right. So back to square one with the speed sensor. Even replaced the tcm with a programmed one for it. Nothing
