#7 of 18 2006 mountaineer transmission
Oct 05, 2010 (4:28 am)
I have a 2006 mountaineer premier edition AWD with a 6 speed trans and 31k miles. I have had it for 18 months and in the winter I heard a whining sound in the trans between 10 to 20 mph and shifts hard into gear. At higher speeds the noise disappears and runs fine. It appears usually on cold days and does not subside when the car warms up. I had it at a trans shop and he found nothing wrong, but did hear the noise. He changed the fluid and filter. Until 1 month ago the noise had stopped, then I noticed it again on a rainy day, it lasted until the ignition was turned off and has not reappeared. Finally last week as we were driving down a grade at about 55mph the trans felt like it was pulsating down hill. Almost trying to shift gears but didn't. Once I accelearated it went away. I was told at the trans shop when the work was done it could be the solenoid valve. He had checked bulletins with Mercury and other shops and found nothing Have you heard of anything like this before.

Help please! I have a 1998 Mercury Mountaineer AWD 5.0 V8. When driving it sounds as though someone is beating the bottom of the truck with a hammer. Any ideas???
#10 of 18 overdrive turns off
Mar 28, 2012 (8:48 am)
I got 2003 MMount, 4.0, 6 cyl, regular trans; and -very often- the overdrive turns off and the button not respond when trying turn it on...this happens driving over 65 mph; and besides the OD off, TRANS overheated msgs appears too. Turning the car off/on resets the msg and sometimes don't show up for the rest of the trip and runs ok.
In the workshop#1 (general) I was told the scan shows code 775; solenoids out of range. I drove it to another -trans specialist- workshop (70 miles) to ensure diagnostic; the vehicle behaves normal, -nothing wrong- and the new scan showed nothing!
Took it to the electric shop to ensure right voltage, and voltage was correct but cca or caa not, so need to replace battery; by the way I left my car with workshop#2 several days for them to test/drive it and look for something mas precise...Do someone have or had any similar experience? Please?? if so, what was the conclusion?

Most likely is solenoids/valve body malfunctions. An easy fix really, but the shops and dealers like to call it a "rebuild" since most of us don't know how a transmission works.

I had the same noise coming from mine almost like an animal had crawled up in the engine. Then mine started to shift funny and we took it in and the transmission was gone! $2,400.00 later........ 2006 Mountaineer with 90,000 miles

Those transmissions were made to go 100,000 miles. Yours died just short of schedule. It's the cost of driving.
My neighbor has an 09 Suburban - just lost their transmission at 60,000 miles.
OTOH, I have an 02 Odyssey with 194,000 on the transmission, still going. My cousin has a Taurus with 300,000 miles on it, original transmission (and engine). Lots of factors go into these events - but 100,000 miles from anybody's transmission shouldn't be denigrated as unfair performance.

When increasing speed from a stop, the low gear(s) do not shift as they should. There is no grinding or loud noise, but the sound is different. The problem does not occur every time you accelerate, but it is becoming more frequent. Is the transmission going out?

That's not enough info for me to help. Specifically, can you describe what it's doing differently?
