    2010 GT500 Cruise Control Issue

    Is there anything in the tune that could possibly prohibit cruise control from working in 6th gear? It works flawlessly in all other gears at any speed but it doesn't work at all in 6th.

    Engine speed and/or throttle position does not match the commanded positions. Log in a lower gear and compare to log in 6th.

    Eric, thank you! I was unaware that the 2007 TR-6060 trans that I just replaced my 2010 TR-6060 with had different 5/6 gears. Thank you for the heads up! I'll make the changes in the tune now.

    We replaced the trans in a GT500, it was the one of the years that Ford got the gear ratio spacing wrong. The new trans had the proper gear ratios and caused all sorts of problems till I figured out what it was. Smart PCM for sure.

    Made the adjustments in the tune for the different gear ratios in 5th and 6th and still only have cruise control in 3, 4, and 5. Any other ideas would be greatly appreciated
