2003 mercury mountaineer transmission does'nt like to shift from second to third. what would cause this

The trans shifts alright through all the other gears but between second to third it allows it to run up to about 4500 rpm then slams into third. I did a trans fluid change, even though I know these trans are sealed and not supposed to have to be change, and it helped a little with the slipping but did nothing for the hard shift. I do have a front wheel speed sensor broke and I have heard that since all 6 speed senors communitcate that that could be the problem. the front and rear wheel speed sensors, the intermediate shaft transmission sensor, and the high speed shaft transmission sensor

No such thing as a seal transmission

Any slipping & slamming & you using it
like that,you may as well pull it & rebuild it

Trans & Power Steering fluids you change every 3 years
on all vehicles or get out your check book for the repairs,
due to lack of knowledge & abuse

None of what you said was fact based or true

    sorry didnt mean to offend you was just going off what I was told by ford mechanic that is all not a certified mechanic myself so was relying on a ford certified mechanic for my information. I will tell him that he needs to go back to ford school, thanks for the helpful insight.

    this transmission has no filler tube in in only a set screw at the bottom of the pan that you take out and shove a tube into to fill until it comes back out at you.

    The trans can be filled thru the drain plug as you said with the proper fill canister you add 2 quarts to & put air pressure to it After you fill it at 180 degrees or more you remove your fill hose & the extra runs out. Your wrong on the tailhousing 3/8 pipe plug As I said it runs out the tube that is part of the drain plug where you filled it I use the plug to fill my Lincoln LS as I know what I'm doing & how much goes in What your told at dealers & shops is just a matter of symantics & they don't care to educate your or that you will understand,they live in the 1950's sorry to say

    Should repeat any slipping is internal wear regardless of how your trans got to that point Changing the fluid makes it slip more in most cases

SOURCE: Transmission hesitates shifting into second and perhaps third gear when driving slow. When acceleration is positive transmission shifts smoothly. Reference "99 Mercury Transmission" as Subject when

Several things could be causing your problem:

  1. Auto transmission fluid is low
  2. Auto transmission fluid needs changing; this is an area that gets neglected by a lot of people;check the fluid and if its brown or gives off a burning smell, it needs changing. Very old transmission fluid will cause slipping in the transmission; if this is the case, it should be changed along with the filter
Hope you find that this answers your question. Best of luck.
Greg

p.s. If you have the fluid changed, make sure it's done from the tranmission pan, not through the filler tube; siphoning through the filler tube can be hazardous to the transmission, especially cars with a lot of miles

SOURCE: transmission locked up, felt like

It was a temporary fault that put the car into limp mode (a safeguard operating condition designed to protect the transmission in case of serious failure). Sometimes a transient fault can occur, and the car goes into limp mode just to be sure it's not for real. Shutting off and restarting the car is the usual way to clear the fault and return the car to normal operation - if the problem was real, the car would've stayed in limp mode after restart, or gone into limp once you started driving again. I wouldn't sweat this one, since it went right back to normal operation.

SOURCE: hard shifting from first gear to second after complete stop

It is in the bottom pan. In order to replace it you have to replace all the solenoids. They are all built into a solenoid pack. What does it do when it shifts to 2nd? Not at all or slips?

SOURCE: I want 2 change 2004 mercury mountaineer transmission fluid

The best way to change it is to flush it out You can do it yourself, but I do not recommend. A shop that is good like a Monro or Firestone usually charges about 100 bucks to flush and that includes the fluid. If you do it yourself, you will save about 60 dollars, but you risk damage to your radiator.

you will need a hose and an adapter. you back out the lower, or upper cooler line for your trans, whichever is the easiest to get to, (Some trucks have an auxiliary engine oil cooler, but make sure you are flushing the trans lines) put the adapter into the rad where you removed the line, and put a hose from each one down into a bucket. Have about 14 qt's of ford trans fluid ready. Put the funnel into the trans dip stick, and start the engine. pour the qts into the dipstick tube while the old fluid is pumped into the bucket. When you have about two gallons pumped into the bucket shut the engine off and reattach the line into the radiator. start up the engine and check your level. Fill with additional fluid if needed.

note: some say you should drop the pan. two things, you only change half the fluid when you do it that way, and second if you need to change the filter because it is clogged, it is too late for the transmission. The filter is only there to protect the valve body, not keep the fluid clean.

Hope this helps

I have a 2003 Mercury Mountaineer 6 cylinder the O/D light is flashing when I go over 45 miles could this mean that I have a bad transmission?

The O/D light flashing is to warn the driver an to suggest he or she take their vehicle to a qualified repair shop. It's telling you a transmission problem exists an fault code's are stored in the PCM/ECM or transmission control module . More then likely it's just a shift solenoid . Take an have code's read ,
