pop out the center trim piece with a flat head screwdriver. Center dash piece may be brushed aluminum or wood grain depending on trim level. It should pop out easily working all the way around it. Then radio is held in with 7mm screws.

Starting with the P0128, the temp that the engine computer will affect the settings it makes to your engine-that particular code specifically means that the ECU thinks the engine is running too cold-and it is telling you that by tripping a P0128. Check to see if your coolant temperature sensor is connected, or just replace it-they are not expensive (usually less than $15).
The P1811 is a manufacturer's specific code, and it means it has a faulty Pressure Control
Solenoid, GM knows about it, there are TSB about it. Harsh shifts when
hot. The best and cheapest thing to do is call GM and complain. Their
number is 1-800-222-1020. These transmissions are known to be defective
but have yet to be recalled. You can try a trans service and it might solve it, if you haven't had one done you should do it ASAP. Another thing you can try is to disconnect the battery, both terminals, and hold/tape the clamps together for at least 10 minutes, then reconnect them, start it up and let it idle for about 6-8 minutes, then gently drive it for another 10 minutes-all your sensors will 'relearn' and it might solve this problem.
The P0300 is a random misfire-who knows what caused that, have you done a tuneup lately (or at all?)- Your coolant leak needs to be found, and that can be done using a pressure tester on the cooling system-with the engine cold, you pressurize the cooling system and watch the gauge-it will drop if there is a leak, and it needs to be found. If you are lucky, it is a hose, but it could be the radiator or heater core, or internal to the engine (head gasket)-not good and expensive. These testers can be 'rented' for free at most commercial auto parts stores.

I think that panel just snaps out,it's held by little spring steel clips ,
comes right out.
code p 0961 refers to pressure control (PC ) solenoid A -- control circuit range / performance===causes wiring---poor connections ---pressure control solenoid---ECM/TCM
at this stage look for poor wire connections or TCM

Ensure that the current PCM calibration is correct for the final drive ratio.
