4L60E/Speedo Electronics Help Needed

I am having problems with my Autometer Ultra-Light Electronic Speedo, the needle bounces around erractically mainly above 50 mph. I have an elecronic cruise that works fine even when the needle fluctuates and also the odometer seems fine. I was messing with it today and it seems that it is mainly when it shifts into 4th gear. It could very well be a problem with the speedo, but do any of transmission guys know if the trans could cause this? Maybe a bad servo or a short? Thanx for anyone that can help!
