Where is the dipstick for transmission fluid in a 2003 Mountaineer w/ automatic trans?

The automatic transmission fluid fill location on a 2008 BMW 650i can vary depending on the specific model and transmission type, but generally it is located under the hood and accessed through a dipstick tube.

To locate the dipstick tube for the automatic transmission fluid, follow these steps:

1. Open the hood of the vehicle and locate the transmission fluid dipstick. The dipstick handle is usually yellow, red, or black and is labeled with "ATF" or "trans."
2. Remove the dipstick from the tube and wipe it clean with a lint-free cloth or paper towel.
3. Reinsert the dipstick all the way back into the tube and then remove it again. The fluid level on the dipstick should indicate the current level of transmission fluid.
4. If the fluid level is low, you will need to add automatic transmission fluid. To add fluid, remove the dipstick and use a funnel to pour the fluid into the dipstick tube. Be sure to use the correct type of transmission fluid specified in your owner's manual.
5. Check the fluid level again with the dipstick to make sure it is at the correct level. Add more fluid as needed.

Note: It is important to follow the recommended procedure for checking and adding transmission fluid to your BMW 650i to avoid overfilling the system, which can cause damage to the transmission. If you are unsure about the location of the dipstick or how to properly add fluid, consult your owner's manual or a qualified mechanic for assistance.

Open the hood and look for either a red handle for a dipstick or one marked trans. Remove the dipstick and ,with a funnel, pour the fluid into the tube the dipstick came out of.

Automatic transmission fluid goes into the same tube the transmission dipstick occupies. It's slightly larger than the oil dipstick and is commonly located further back in the engine compartment than the oil dipstick. You should make sure not to overfill the transmission fluid. Add only until it appears between the indicators on the trans. fluid dipstick.

Transmission Fluid Automatic Trans. Fluid Level Checking

1. Park vehicle on level surface.
2. Set parking brake and chock wheels.
3. Warm up engine. NOTE: Allow automatic transmission fluid to reach 140-158 degrees F (60-70 degrees C).
   
4. Move shift selector from "P" to "1" and then back to "P".
   • Automatic transaxle fluid level should be in 65 degree C range on dipstick.
5. Add SK ATF SP-III (or Diamond ATF SP-III) if required.

Usually you just add transmission fluid through the dipstick tube, given its a automatic. Have the vehicle warmed up to operating tempature and check the trans fluid. Remove the trans dipstick and place a small funnel in the dipstick tubes opening. Add the neccessary amount of fluid and recheck. Be aware though that between adding fluid and checking the fluids, you need to allow enough time for the trans fluid to drain all the way down the dipstick tube or you will get a inaccurate reading.

I have recently changed and added fluid to my 2003 Mercury Mountaineer with help from a Chilton manual. None of the answers posted so far are quite correct...and since I researched this for months before finding a proper solution I figured I would let everyone know how to do this.

Tools needed: Mercon V trans fluid, torx head socket to remove trans drain/add plug, an adjustable wrench to loosen the main bolt on the drain/add plug, a pump to add fluid back in, and (if possible) a temp gun like a service station would use. Last, but not least, you will need a special nozel that fits in the bottom of the drain hole to add fluid back in with. (I could only find this at OReilly's. It was a special order from 'OTC' <OTC Part No. 6604>

In my opinion this is a terribly designed transmission. To add, remove, or check fluid follow these steps:

1. Heat fluid to 180 degrees F.
2. Raise entire vehicle using a level to make sure the vehicle is completely level.
3. With foot on break, shift through all gears, place back in park.
4. Go under transmission pan, and by using torx head socket (and PB blaster or you'll break the socket), Loosen the middle plug on the main trans drain plug. (There is a larger bolt head on the drain plug with a smaller plug inside it)
5. Replace center plug with OTC part No 6604.
6. Loosen, (but not all the way) the main bolt plug.
7. Now, this will tell you your fluid level. (Per Chiltons manual: If fluid pours out your trans is overfilled. If fluid drips out the level is ok. If no fluid comes out, add and repeat until you get a slow drip, indicating the proper level.
7B. If you need to add fluid, at this point you would use the pump. They make plunger pumps for differentials that are supposed to work well, but I used a simple $3.99 bulb pump just fine.
8. When level is correct, tighten main bolt.
9. Remove OTC No. 6604
10. Replace center plug with torx head socket.

That sounds complicated but it's not bad once you have what you need. The BIG problem is that this IS a sealed trans. Ok for BMWs...not so good on a Ford products! SO, if your fluid level begins to become inconsistent be vigilant. Because there is likely an underlying problem causing this.

Temp Gun Note: The temp gun is to make sure your fluid is at 180 degrees. However, Chilton reports that this is about where it would be after driving around the block a couple times. Since I'm not a pro, and don't have one, I did the latter and it worked fine.

HOPE THIS HELPS!!! This was tough for me to research, but my Mountaineer runs fine (relatively speaking :) and I know very little about fixing cars. Just researched it till I found the correct fix.

Peace, and good luck!

It does not have a dipstick.To check the fluid trans fluid has to be warm then you take the allen screw out of plug in pan, see 1st pick and you should have a steady drip from the hole. If you have to add fluid you would need the special tool shown in second pick and a tool to pump fluid in.

Dipstick is to the left of the engine. Should be a small yellow dipstick. Add fluid through the dipstick hole. The vehicle should be running when you do this. It is best to have driven at least 20 miles before adding trans fluid so everything has had time to get hot.

nope there is no dipstick, to put fluid in, you have to take out the inner drain plug, if you look on the trans pan you will see a drain plug with either a torx or allen head plug in the middle, take this out with the engine running and at normal temperature, dont worry fluid will not come pouring out (there is a standpipe that goes up into the trans) to add fluid you need to squirt it up through this hole with a tube or whatever you can find that works, when it is full you will have a steady drip from the plug, thats the only way to do it. hope this helps
