If it shows "D5" in the scanner then make sure it says D5 in VCM Editor.

Those tables are just the maximum's, so it will shift regardless of input. It may prevent the TUTD system from enabling if the tables are set incorrectly. For now you can set all the upshift speeds to 100, and all the downshift speeds to 0 to rule this out.
