I wasn't asking if you had the feature . I was asking if the delay was working .
An easy system check is to bridge the in/out vac line at the Switch Over Valve and go down the road to see if you have shift delay. If you do , then the element/actuator part of the system is working but the SOV/ECU activation is not.
If it still does not work, a bad servo element at trans is suspect. See if the line from SOV holds hand vac. Bad element is a common failure part for shift delay system. Some guyjust BB the line and use lower gear until collant temp is warm. [ but that does not solve the CE]
