I believe that is a 4R70W
The first model year for the Mercury Mountaineer SUV was ( 1997 )
4r70w
Starting with the 2002 model , there is no automatic transmission fluid dipstick on the Mercury Mountaineer ( and the Ford Explorer , 4 door )
It doesn't have a dipstick for the automatic transmission - not since the 2002 model
Since the first model year of the Mercury Mountaineer is the 1997 model it would be ( r134a )
The first model year of the Mercury Mountaineer was 1997
( 4R70W ) automatic transmission is used on the 1998 Mercury Mountaineer 5.0 L - V8 all wheel drive
The first model year of the Mercury Mountaineer was 1997
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 first model year of the Mercury Mountaineer sport utility vehicle was 1997 Did you mean 2005 ?
1997 to 2009 ( so far )
1997 was the first model year for the Mercury Mountaineer
