Unless if you don't plug it in all the way. Then it acts exactly as the failed sensor did.

The plug sits atop the transmission and requires that you sort-of bear-hug the tranny and feel your way. I guess I just didn't plug it together far enough the first time. It nearly fell apart when I checked it. I knew right then what had happened. I firmly plugged it together until I heard the snap of the connector latch and have had no problems since.


Thanks for all the input guys, I really appreciate it.

Glad you figured it out man!!!

LOL. It is usually the culprit though... so I just got lucky. I'm typically never right. Theres three ways to do things in my opinion:
1. the right way
2. the wrong way
3. and my way (which is exactly like the wrong way, just much much faster!)

That's funny!

Man, I was hoping this thread would just die, go away or get lost about 50 pages deep but when I saw you guys had replied to it, I knew I had to come clean.

Thanks again for the replies.
