There is no dipstick. It is a matenance free trans.

On a 1989 Mercury Grand Marquis : The automatic transmission fluid level dipstick should be in the engine compartment , near the firewall ( the metal wall that divides the engine compartment from the passenger compartment ) just towards the passenger side of the vehicle ( where the rear of the engine connects to the transmission )
Check under the hood, passenger side, between fire wall and engine, look down.
Rear of engine near firewall.
You pour it through a thin necked funnel into the dipstick tube
I was not aware that the Grand Marquis came in a manual Transmission! If it was an Automatic Transmission I would say take it to a Transmission Shop and have it looked at.

Look at the back of the eng. by the firewall on the passengers side, it should say TRANS on the handle
Oh, dude, the transmission dipstick on a Mercury Grand Marquis is located towards the back of the engine bay. It's usually a bright color, like yellow or red, because, you know, it wants to stand out in the crowd of car parts. Just look for a long, thin stick that's like, "Hey, I'm the transmission dipstick, come check me out!"
It is the Dipstick plug. When the transmission is manufactured they put the plug in and when they put the dipstick tube in the very first time it pushes the plug into the transmission. Nothing to worry about. Just throw it away.
No ( motorcraft . com shows the 1995 Grand Marquis transmission as an AOD - E and the 1997 Grand Marquis transmission as a 4R70W and different part numbers )
