Speed sensor problems, need help Badly!Experts welcome.
Ok, I've been having problems with my shifting and speedometer. My speedometer doesnt move at all till about 40kms per hour, and then it flickers up and down very erratically. Once hitting the first shift in the automatic transmission it shifts about 2 seconds too late and someone "bucks" me. I read a prior post that said change the speed sensor in the differential which i did, and it did not help. So now I'm not sure what it is. I picked up a speed sensor for the transfor case, and went to check out the transfer case to find where it goes in and its nowheres to be found, so that can't be it. Had a mechanic friend look at it and he said that sensor in the rear end should be the problem, so I'm not sure whats going on?? Could there be rust or dirt underneather the sensor in the hole that may be blocking the sensor? Or maybe it is the wire that clicks into the sensor that is not working properly? Any help would be HUGELY appreciated as this problem is really starting to get to me, help please!

Don't spray water in there. It goes straight into the rear end, and so all that water will get mixed with the grease, and it won't be pretty. It's a magnetic sensor, so dirt shouldn't affect it. At this point, I would suspect the wiring more than anything. You'll have to trace it somehow and see if you can find a point where there is a break or a short. Might also want to check the connection with the cruise control.

Auto trans or manual? If it's a manual then you probably don't have a speed sensor in the trans.....
