Engine/Transmission (1994 - 1998) No Overdrive

Question on the transmission relay switched power side.

I have 12v to relay from battery but on the 12v to relay from ignition switch I get a 12v volt flash of power then goes away. So no power to plug at top of transmission with key on, but I do have 12v when running.
Is this normal, from what I have read there should be switched power to the relay. This is for a 98 12 valve 47re

The PCM gets a momentary ground from the OD Off switch then commands OD off. Same thing when it is pushed again, momentary ground to PCM commands
OD back on.

Yes but me question is at the transmission relay. Should pin 10 in the pic have 12v with key on engine off?

Sorry, I misunderstood your question. Maybe cerberusiam or someone else will step in here and help you with this.
