It's been this way for 2 years. When put on diagnostic machine, said speed sensor, transmission or electrical.

yes it only tells you the bad circuit not the actual sensor or problem. thats or job to determine. the repair could exceed the valve of the car in your case,so you might leave it alone for now

If left alone will it cause more problems to the transmission?

possibly but the cost of this repair could go from 400.00 to 2500.00 depending on what's wrong.
