I got an error code pointing to the transmission speed sensor at the same time the overdrive and speedo stopped working. Got a new speed sensor from a parts store and had the car in the shop last week for shocks, tires, exhaust, etc., so I asked the mechanic to put in the sensor while he had the car. When I picked the car up he said he couldn't find where it went. I THOUGHT it attached and plugged in to the transmission somewhere but he said he looked all over the place and didn't see it. Where DOES it go? Thanks in advance! p.s. I'll post a jpeg of the sensor if it helps..
