97 E420 Speed Sensor Not shifting

I have a 97 mercedes e420 that has stopped shifting into higher gears. It was having misfires earlier, I changed the coils and fixed that problem, now the code reader is saying something about a speed sensor. I looked up the price of a speed sensor at autozone, they said it was $112 dollars. Where is the speed sensor in the car, and how do I change it or fix the problem?

You have a W210 and we have a very active forum and a lot of DIY sticky threads. Look for us in the sedans section and read the Transmission FAQ in the stickies. Then post the exact code you are getting. Chances are you need to replace the conductor plate which is where the speed sensors are. Lots of diagnostics and instructions in our forum. Welcome and good luck.
