Question about 2003 Mercury Grand Marquis

1 Answer

2003 Mercury Grand Marquis w/ less than 100k miles-lost reverse; all other gears fine.

I was pulling my 2003 Mercury Grand Marquis into my driveway and decided that I needed to back-in so that I could unload the trunk. When I shifted into reverse, I heard a loud pop and some additional non-savory noices plus the entire car shuttered. At that point, the car would no longer go in reverse; all of the other gears work fine. This car has less than 100k on it; I keep it well maintained and drive rather conservatively. Am I looking at a transmission rebuild or could there be an electrical gremlin behind this such as the automatic transmission solenoid? Thanks for any assistance.

    We took the car for a test drive this evening; the car is shifting very late...it almost feels like the transmission is slipping. In park, we ran through the gears and it moved ever so slightly in reverse and then quit moving. One other thing we noticed is that there were 2 trails of fluid on the ground from where we pulled out to test drive it. Also, we checked the transmission fluid levels and they were normal.

Usually what causes this is your reverse clutch is worn out in the transmission, or there is a bad valve

How do you stop your trunk from opening when you put your car in reverse?


You have a short between the trunk motor and the reverse lights. Follow the harness from the trunk latch to to reverse lights. Open the harness there and start looking.

Atv won,t shift into reverse


2004 Mercury Grand Marquis is not an ATV. Reverse on some ATV's has a knob on the handlebar attached to a cable that sometimes goes out of rig. (the cable prevents shifting down past neutral unless pulled)

I have a 1993 mercury grand marquis and reverse doesn't work after it warms up. It does work when cold.


You can check with a local transmission shop, but usually the problem is a worn band or a weak pump. The reverse band also affects low gear.
There may also be a solenoid involved.
