I recently cleaned the throttle body on my 2009 GMC Yukon XL.i completed the relearn procedures,but acts as though the trans wants to take off.  The relearn procedure I ran was --crank,run for 3 minutes turn off for 60 seconds crank run for 3 minutes.drive for 10+ miles above 44 mph with decreased speed, increased speed but not over44. Do I need to do the relearn procedures over or carry to dealer

Re-learn?  What do you mean by "take off"?  What were you trying to fix before you cleaned throttle body?

Try removing both battery cables (negative first) then clean both posts and cable ends.  Reconnect battery (positive first) and drive your vehicle normally.  Systems that learn how you drive do not require a special sequence.
