Hello!

I have a blazer I am swapping a manual into, have found matching OS to do a segment paste job and am confused to the tune for the manual transmissions.

Why does the manual transmission tunes have parameters that would run an automatic? TCC is not in a manual and upshift, downshift options. an its only showing its a 4 speed and the manuals all should be 5 speed. But looking at the rest of the tunes with a manual I see they have the same parameters available. When I did the segment swap, after saving, the segment ID and checksum numbers changed to what the camaro numbers were. So I assumed it flashed correctly.

Any one know why this is?? Thanks in advance!!
