Well seeing from your signature you are catless without a proper tune so thats the cat code. I would look into the sensor circuit code because if that's not reading proper the ECU can not calculate the amount of torque the engine is making leading to is setting the other code? Just my guess and where i would start

 

The catless code is the one code I don’t Care about. Pops on about every 150-200 miles.

After I shut the car off outside the store, I let it sit for 10 min then turned it back on after I cleared all of the codes. No problems , drove the car 2 miles back to my buddies house, left it off for about 45 min, then turned it on again and still no codes and issues with the transmission. Drive it back to my house 45 minutes again with no issues.

I’ll keep looking into the others.

 

How does a transmission shake... and how would you know?

 

From the center console the car started to vigorously shake so it shut it off immediately.

 

Yeah keep us posted if you find something or it happens again.

I get the odd random code or one off reduced power (turbo won't build boost) but I clear it and car seems fine on the next drive so I don't worry about it. Hopefully it's something like that for you too

The only other time this happened was back in November, but that time it wouldn’t let me take the car out of park so I had to leave it for the night, came back the morning and the codes cleared themselves and this is the first time since. Should I be worried or is the infrequency of the code nothing to worry about?

 

The code you should be concerned about are your MAP sensor codes. Your transmission shaking is likely from your engine idling very rough due a bad MAP sensor. Additionally, the ECU is probably rejecting requests from the transmission because the engine operation has been compromised. A bad MAP sensor can wreak havoc on your engine, not to mention it can cause engine failure.

 

^ what he said

Could also be related to that racechip you got. Haven't seen many peeps here run one but if it's sending bad data it could be the source of your issues. Normally things like those intercept the readings from the sensor and change them before sending a new signal to the ECU (assuming it's a piggy back and uses the MAP sensor, like I said no real experience with them)

 

Update: believe the harness on the racechip was the problem. The clip seems to have broken by user default so I replaced the harness and hasn’t happened since. I’d assume since the clip was broken when I hit a hard pothole etc it slowly was separating the sensor.
