CEL code PO2716??wth?

My buddy brought by his wifes 05 Corolla...cause the check engine light was on...I got code PO2716....

I looked in the book and it doesnt exist...

I looked online and the codes listed dont go up that high....

I am almost positive thats what it said ..I read it a dozen times..then cleared it..

he still wants to know what that was and now so do I

P2716 = Pressure control solenoid D performance or stuck off

It sounds transmission related:
