car back fires

hi guys, i also have 2000 chrysler intrepid, i believe that my question is general for all "automatic trans." cars. As was coming home an hour ago, in the highway, @ 110 km/h , the car suddenly lost control of gears, "like putting your gear in neutral and pushing the gas", and the car made some weird noises. Then after 4 secs, it went to the right gear and was all fine. It did this 2 times only as i was coming home, and after it did that, i still had an hour of trip left, it never did it again. By the way, there's lots of snow and ice around in the roads.
I believe theres a transmission problem, and once again, this is an automatic trans. chrysler intrepid, 90 KM on it.
If you can help out in anyways, its greatly appreciated. thanks

There is a link between your talon and your intrepid. Chrysler manufactures a large variety of vehicles including some I found out just recently. Chrysler makes cars in the same manufacturing plants as Dodge, Plymoth, Eagle, and Mitshubishi (of which chrysler owns part or all of these companies). Not only does some of these companies use the same names on their cars they also use the same bodies, engines, and transmissions etc. It is mainly a select few automatic transmissions that chrysler puts in their cars that has problems with overdrive. I should know because I have a 1992 Eagle Talon that just went on its 5th transmission at 87K miles. I just pulled the same model chrysler transmission out of a 1990 eclipse that I cannot yet try out since my car refuses to start. Not all of chrysler's transmissions have this problem but the one in the early model talons, eclipses, and lasers have a bad case of tranny problems. Usually the first thing that goes is the overdrive; it will miss shifting occasionally and more often the more it is driven. When it gets to the point your overdrive doesn't work anymore, thats when the other gears start acting up, usually with 1st next. It is much cheaper to buy a used tranny to put in since a new one would cost as much as 10x as used one. You are describing the same problems exactly how mine started going out the first 4 times (the 4th tranny worked fine, until the CV axle busted a hole in the side).

i took the 2000 intrepid to the chrysler dealership service, they did some sort of tune up to the engine, they told me the transmission wasn't causing the problem, it was actually the engine tune up. One way or another, they charged me $1000 bucks, but the problem is gone now, thats the good thing. thanks for ur advice though

Hmmm, think to yourself. Psychologically do you believe the problem is gone because they said it is fixed, or does it still exist but hasn't resurfaced yet? I've had to rethink several problems like this before. If its fixed, good luck with it.
