I had my transmission rebuilt on my 2004 Mountaineer. I believe it cost around $1800
Yes.
I am pretty sure that it is non existent, i have a 99 mountaineer and it is AWD and i am going to assume that yours has either FWD or AWD which means it has a transmission and a transfer case not a transaxle
passengers side of rear housing of transmission
you do not it is factory sealed the fluid if no leaks will last a life time so ford thinks
That would be the 4.6 liter engine, which takes six quarts. * of 5W-20 according to the 2003 Mercury Mountaineer Owner Guide
check reverse light switch on transmission.
You can check the transmission fluid, there is a little window on the side of the transmission on the drivers side that shows the fluid level and you can also add transmission fluid on that same side. There is no dipstick to check the level.
It is in the fuel tank.
It is on the side of the transmission where the shifter cable bolts to. It is built into the neutral safety switch.
Most likely worn engine mounts or transmission mount.
I had the same problem with my 2002 ford explorer in 2008. I took my vehicle to the dealership and ended up having to have my torque converter which is inside of the transmission replaced. Yes it was costly!
