If so what is the code, if not you can check for history or pending codes… You may have to go to live data on a scanner to see if the shift solenoid is being commanded to shift into OD (overdrive) or not, if it is but not shifting then you have a wiring issue or bad or sticking OD solenoid or even the TCM needing rehashed or replaced… Also check your ECT (engine coolant temp) as to low a temp can cause the OD not to engage… IIRM a CEL will cancel the OD on your vehicle… ---

Have you accidentally hit that little overdrive button on the shifter? I do that sometimes in my Highlander (2007), and people who borrow it often do that.
