Try the easy stuff first. Change the spin on filter and clear codes. Any other P07xx codes?

I changed the oil and filters in the trans last night
same thing happened to me this morning on my way to work
I have been to the dealer with this several times
never any help of coarse they send me to Allison direct and Allison sends me back to them. I feel like I am in a game of tag all I hear is "Not it" from both.
