Ok, last night on way home after work, doing about 65MPH on freeway. All of a sudden the speedometer goes to 0MPH & my car just revs free. No drive in any gear but still running. I am coasting & hit the manual switch & now I have 3 gears. I manage to get off the freeway & stop. I pull the FWD fuse I had installed (torque bind issues) and the car drives & shift fine, just no speedometer. About a mile from home the check engine light comes on but still driving fine. I am going to start by checking codes & the speedometer cable. Not sure what the cable would have to do with shifting but it's a start. Any thoughts on this? Thanks. Pat
