1988 560SEC Passing Gear

I have not been able to kick into passing gear on my 1988 560SEC. Could this be a problem with the FPR? It will speed up but does not kick down. Any ideas on where I should start looking?

Yes, the Fuel Pump relay is a possible culprit. But check the kickdown switch first before you swap the relay. After that there is linkage that can be adjusted but thats less in need of messing with.

Welcome to the forum btw! :)
