You have a problem with the transmission itself not the gear changer.
What you have I suspect is the so called Limp Mode, it is intended to save your progress tranny from serious harm.
The answer you had from ala_xfire is probably correct. You vpcan check to see if there are any codes stored using a code reader. If you intend to do work on the car this is what you should buy.
