According to the 1997 Mercury Mountaineer Owner Guide :
( the 4R70W automatic transmission used in two wheel drive and all wheel
drive versions takes Motorcraft MERCON automatic transmission fluid )
* the type used should be engraved into the automatic Transmission Fluid dipstick *
Motorcraft MERCON automatic transmission fluid ( 2.64 pints / 1.25 liters ) is used in the transfer case of a 1997 Mercury Mountaineer
Your 1997 Mercury Mountaineer came from the factory with ( Motorcraft MERCON automatic transmission fluid ) in your 4R70W automatic transmission ( the type that you are supposed to use should be engraved in your automatic transmission fluid dipstick just to confirm )
According to the 1997 Mercury Mountaineer owners manual : Your 4R70W automatic transmission capacity is ( 13.9 quarts ) * that of couse would be for the transmission , torque converter , lines , transmission cooler , etcetera *
In a 1997 Mercury Mountaineer : ( 4R70W )
According to the 1997 Mercury Mountaineer owners manual : Your 4R70W automatic transmission takes ( Motorcraft MERCON automatic transmission fluid ) * the type that is used should be engraved into your automatic transmission fluid level dipstick *
According to the 1997 Mercury Mountaineer owners manual : ( 13.9 quarts / 13.2 liters ) for the 4R70W automatic transmission ( rear wheel drive and all wheel drive ) ** that would be for the entire system , transmission , converter , lines , etcetera **
If you have a 1997 to 1998 Mercury Mountaineer or Ford Explorer with a V8 engine, you will have a 4R70W transmission.
The first model year for the Mercury Mountaineer SUV was ( 1997 )
Motorcraft MERCON V - automatic transmission fluid - according to the owners manual
On a 1998 Mercury Mountaineer : Using a funnel , add the automatic transmission fluid through the automatic transmission fluid dipstick tube . It is located near the firewall , just to the right side ( passenger side ) of the engine , where the transmission is bolted to the rear of the engine . ( the type of transmission fluid to use should be engraved into the dipstick )
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 .
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.
