P0335 is a code for a faulty crank angle sensor. When this sensor starts going bad, usually the car will not start till it cools down, may cause rough running or no start at all. P0727 is a communication error between the engine control module and the transmission control module. Check for any bad connections between both modules.

My 2000 cadillac catera check engine light is on and the tc light is on and it idle's low


What have you done so far. I would start with looking at the cars repair/maintenance history. Have the codes read (might be helpful). Could be anything, depending in what direction you need to go you might want to check for cyl. miss-fires, bad coil, IAC, fuel pressure, clogged CAT. CMP sensor. Let me know if I can help anymore.
