4l60e questions Having code issues with my LS swap 4l60e. Bones stock, used 4l60e out of a 2002 camaro. I was getting a manifold pressure switch code so i changed that. And now i get a TCC code and 1-2 shift solenoid code. But, ill still get a manifold pressure switch code every other start up and when i get that code, i don't get the TCC or solenoid code. But when i don't get the manifold pressure switch code, i get the TCC and 1-2 shift solenoid code. I havent driven the vehicle but around the block once before i replaced the pressure switch. Im running a stock ecm thats just had the basics done to it just to get the swap running, it hasn't been tuned yet. Am i getting these codes because i need a tune? Or if i drive the car around will the computer re learn something since i changed the manifold pressure switch?
Im not a transmission guy at all so please go easy on me lol

Computer is for a 5.3/4l60. Its just had the basic deletes to let a swap run. Harness is a DBC set up for any gen 3 engine. The harness is from amazon and the computer is from Ebay.

How does the ATF look?
...Hopefully not full of Metal.
Do you own a Digital Multi-Meter?
Are you using a New GM Wiring-Harness?
...A Used GM Wiring-Harness?
...A Modified GM Wiring-Harness?
...or an Aftermarket Wiring-Harness?
What is the condition of the Wiring-Harness?
It would be good to know which PCM you have, and which Calibration-Number you are using.
Please Post that information.
What are the Current-DTCs, and what are the DTCs stored in History?
Which DTCs have been made inactive?
