CAMARO6 - View Single Post - Hard shift when braking, just 11k miles (no warranty)

pisters · 01-31-2023, 07:12 AM

I have a 2021 Camaro 2.0T 1LS with 11k miles that out of nowhere started making a noise when it is braking (downshifting) and sometimes it makes it violently. Testing the sequential I found that when I downshift from 3 to 2 in low gears it makes a BOOM type noise. I am surprised that the car being so new has problems so quickly. My car has no warranty as I am not from the USA and it is imported.

I was suggested to reset the TCM but I can't find any steps on how to do it. Can I do it with a LAUNCH scanner? What steps should I follow? Sorry for the question but I searched a lot and found nothing about procedures. I will be grateful for any help
