The errors P0170 and p0171 have nothing to do with the transmission they are fuel trim codes. I would check the input shaft speed sensor and the gear position sensor electrical connectors for corrosion and if clean replace them. Here are instructions and diagrams to help you find the components. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
