Ok I have a chevrolet impala 2000 3.8L and it is an ex-police cruiser. I got it in January 2007 with 112,000 miles on it. So far I have had the spark plug wires changed, spark plugs, fuel filter, air filter, oil changes of course but never the transmission fluid changed. I took it to many car shops and asked the mechanic about changing it and they all say NO. They say if I have not owned the car since day 1 and have no history of maintenance especially transmission fluid changes, not to do it cause the transmission may lock up with a new change.

Is this true or not? am I safe to go ahead with a new transmission fluid change? The car now has close to 140,000 miles on it now.

The car was probably on a prventative maintaince schedule. If the fluid does not smell burnt and still has the red color to it I would change it.

Is there any truth to this theory? My car has just over 90K and the tranny isn't as smooth as it should be so I am thinking about having it serviced. I am the second owner so I don't know what has ocurred prior to 65K.

I would have it serviced. You may save it. If you use it the way it is it probably will get worse with time.

an article I read a while back- dealt with the scenario where a tranny hasnt had the fluid changed in a long time.
They get the fluid changed/ get a flush and filter change... and a few days later the tranny fails.
the article stated that many times- over time the tranny had some of its little passageways become clogged with whatever clogs stuff... be it grime or metal particles....
when they did the flush and filter change- this unclogged some of the blocked stuff - and now the tranny was working as it was supposed to- but it also uncovered stuff that was hidden by the clogged passages- and the tranny soon failed.
article made alot of sense.
but like mentioned- if it was a police vehicle- it most likely was on a severe duty maintenance schedule.... I would go ahead and change it.
