Down the tube that holds the trans dipstick.
There is no transmission dip stick for a 2002 mercury mountaineer, fluid will need to be checked from under the vehicle. There is a fill plug on the transmission, remove the plug and fluid level should be up to the level of the plug hole. This is the only year mercury did this in the mountaineer.
Starting with the 2002 model , there is no automatic transmission fluid dipstick on the Mercury Mountaineer ( and the Ford Explorer , 4 door )
how do you change the transmission pump in a 2002 mountaineer
The 2004 Mercury Mountaineer does not have an automatic transmission fluid dipstick . I know that the 2002 and newer Ford Explorer four door versions do not have a dipstick for the automatic transmission fluid level .
They have a sealed transmission you dont have to fill it. The fluid should be changed around 100,000 and it has to be done by a dealer.
I assume the 2002 Mercury Mountaineer would be the same as a 2002 Ford Explorer ( No , starting with the 2002 model there is no automatic transmission fluid level dipstick ) Ford has a way of checking from underneath the vehicle
The transmission fluid can only be checked with a special tool from Mercury (there may be aftermarket tools). A plug on the underside of the transmission must be pulled and the tool inserted. The short answer for regular driver maintenance is, "No."
On a 2002 Mercury Mountaineer : ( DOT 3 brake fluid meeting Ford specification ESA-M6C25-A ) According to the Owner Guide
It doesn't have a dipstick for the automatic transmission - not since the 2002 model
there isn't one, the transmission is sealed for life and not DIY servicable
There is no dipstick, the transmission is a completely sealed system. You have to take to dealer for service.
According to the 2002 Mercury Mountaineer Owner Guide :The washer fluid for the rear liftgate is supplied by the same reservoir as thewindshield ( located in the engine compartment )
