there werent any accidents, no precusors or warning signs that there was trouble with the transmission, just parked it one night with no problems and the next morning it wouldnt shift into 2nd gear (automatic) and more recently stopped shifting period, R D 2 or 1?!
What would cause my transmission to not shift into 2nd and then not shift at all on 1996 Pontiac Sunfire

Check the transmission oil level after that, servicing the transmission may be the first and cheapest place to start. In servicing the transmission the condition of the oil will be checked, the oil can be checked for debris, the filter and magnets at the bottom of the oil pan can be inspected, and on a test drive afterward the shifting of the transmission can be checked to see if the transmission may have further mechanical or electrical problems.
