started losing power ,did not want to go pas 30 miles per hr ,then it ramed up and came to a stop with no acceleration ,i shut it off then start it again and was able to get home at a low rate of speed while continuing to have these problems, another day while far away from home the engine rammed up again minimizing my speed as the transmission was slipping and not go fast then my O/D over drive went on flashing a light ,while the engine kept steady at 20-30 miles per hour while accelerating increasing no speed ,now my SUV will not run wright, it will kick into gear at times constantly and cause problems driving safely ,this is a common problem I'm hearing and reading in the internet with the ford/ mercury mountaineer the manufactory does not want to accept responsibility with this problem ..... this is clear a RECALL ISSUE that needs to be addressed before someone gets killed on the highway by getting rammed by a semi-truck which it almost happened to me !!!! a multi-million dollar law suit is in order if they do not acknowledge and fix this problem

Transmission lever binds when attempting to shift into park, slipping into reverse instead. Problem has occurred sporadically from 2007 to date. Usually the miss-shift is noticed because it just doesn't feel right, but not always. It can be most dangerous if you don't turn off the engine immediately (after attempting to shift into park) and take your foot off the brake. That has happened to me about 5 times over 5 years. It happened twice at a gas station, once at a car wash, once in a shopping center, and once in front of my house as a child walked behind the car. In each case the car only moved 1 or 2 feet before I realized it, and was able to step on the brake. These days I don't need to worry about it as much because (at 52,000 miles) the transmission takes 5 - 10 seconds to engage the reverse gear and then it bangs into gear, loudly alerting me that it didn't go into park.. The transmission is defective, and ford knows it.

Extremely hard shifting into reverse. Slipping in 3rd gear when transmission is running for 15 minutes. Over drive light flashes and transmission fails to work while on highway. I have to shift into neutral turn the car off then back on (while at 65mph) then it works fine the rest of the day.
