Can I change the Speed Sensor in the Trans. and how do I do this " simple " job.

This is Kevin with NWA Auto Shop. Without seeing the vehicle, I can only theorize. Based on the limited information given, these are my thoughts. A) There is now way for me to know your level of mechanical ability or the tools you have at your disposal. Changing the speed sensor is not difficult as compared to doing a timing belt or chain. However, with the proper information researched you should be able to do it with basic wrenches and tools. Kevin
