can a computer code tell why a 2002 Cadilac deville would suddenly lose all gears?

Question

traveling along at 65 mph and all of a sudden the transmission lost all gears including reverse. pan pulled oil level fine, no signs of anything wrong at all. filter clean. discovered one 30 amp fuse under the back seat, replaced fuse all fuses good now still no difference. current codes are b0429, c0660 and b0100. Can anyone tell me how to find out what my codes mean?

Answer 1

B0429 Auxillary air temperature actuator

C0660 Automatic level control

B0100 Inflatable restraint electronic frontal sensor

None of these codes are for the transmission. You would need to gather a "P" code from the powertrain. If the vehicle was traveling and all of a sudden lost  all gear incuding reverse the most likely event that occured is the transmission pump failed. Without the transmission pump feeding the torque convertor there would be no transmission fluid pressure. Nothing else would do what you describe, this is a mechanical condition. To diagnosis this a transmission pressure test would need to be performed.
