How do you change the transmission oil on a mercury mountaineer?

Answer 1

Someone on this site said you can't, but I did! First I drove the car up on front-end ramps and put the vehicle in park, set the parking brake, and put blocks behind the rear wheels. (if your crawling under the vehicle, think safety). By the way, I forgot to mention that I went to autozone or advance auto parts, (forgot which), to get an automatic transmission filter and a transmission pan gasket, along with a case of Transmission Fluid. The transmission filter and pan gasket comes in a kit. I then took the transmission pan off, (you'll need a very large floor pan to catch the old transmission fluid). Just take a few bolts off at a time to let the fluid drain into your floor pan, that's so you don't make a big mess. Once you drain the pan and take the pan completely off you'll see your old filter up in the front right, this filter comes off easily, (just pulls right out). Also, when you pull the pan off you'll see a small white plastic ball, (free floating), don't be alarmed, it's supposed to be in there to seal an overflow tube, most mechanics just throw them away, but I think if Ford put them in there, I would put it back in. Slide your new filter in. Clean your pan lip off good, put your gasket on the pan, slide your pan into place and start re-bolting the pan. I forgot what the specs were for torquing down the bolts, but you can find that at ford.com or probably even at autozone. Be careful not to over-tighten and strip out a bolt, then you'll have a leak. I recommend you use a torque wrench for that reason, (and personal experience). Once you've got it back together, just fill-er up. I also forgot how many pints of fluid it takes, but once again you can find that info at ford.com or autozone. Keep an eye on how much fluid you put back in, don't overfill or underfill, check the dip stick. One last thing, this doesn't remove all of the fluid. What ever remained in the torque converter is still there. The only way to remove all of the fluid is to take it to a transmission shop where they have the pump to drain it completely. When you take the pan off, make sure you clean the whole pan well. And there you have it. It was about a two (2) hour job for me, but then again everything went well. Hope this helps and good luck.
