I just swapped a camaro over from a 4l60e to a th400. The car was already running cos#5. I took and did a campare from a mn6 camaro with cos#5 that I tuned and copied both the trans segments. The car will now not go above 2,000 rpms. I can flash it back to the old tune cos#5 with the 4l60e and the car runs and drives fine just has a lot of faults. I have to have the car a mn6 to use the shift light function. Any ideas, Im lost.
