The service engine light comes on and 6 different transmissions trouble codes are set in the computer causing the transmission to go into a default mode that causes it not to have a first gear or high gear. The electrical dash gauges moy or may not work at times and the key may or may not come out of the switch when you try and shut the car off. I checked with a gm dealer and talked to the mechanic and as soon as I showed him the trouble codes and the number of times they had came up he told me what the problem was as he had seen it on many other gm cars before.
