2000 Grand Marquis
I just bought a mercury grand marquis with 150000 miles on it and have been going through routine maintenance. I was wondering if i should change the transmission fluid since I'm not quite sure the last time it was changed if ever. Thanks

Since it's at that mileage do a drain and refill only. And keep the old transmission fluid in case it starts slipping.

I would leave it alone because if you change it now it might start to slip
