97 Jetta auto trans stuck in second gear.

I have a 97 jetta with 2.0 auto trans.  The trans is stuck in second gear.  I put it in drive and it takes off in second and stays in second.  I try manually shifting it and nothing.  Just stays in second gear.  Has anyone else had this problem or know how to fix it.  Could it be just a relay or sensor somewhere? 

I'm actually having that same problem right now with mine.  I know someone else that had this and it ended up being her transmission sensor.  I'm going to try to get my sensor replaced this week.
