Transmission still shifts okay, but in the last year or so, it has started to shift rough and erratically. I suspect it's on it's way out, but I can't afford to do anything about it, so I guess I'm just going to see how long it will last before it grenades....
I wouldnt wait for that to happen,why have the car sit in the back yard and deteriorate? Just p/u some decent fluid/filter and change it.It really isnt that much money to do a service on a Cavalier transmission. Plus,it will save you all kinds of money in the long run. BTW,it sounds like your filter is the culprit.

Unless your plan is to get another trans from the auto wrecker?
I am a bit ashamed to admit this but I suspect the transmission fluid in my Neon could be the original fill. In the manual it is described as maintenance free and my grandfather had the car until 2000. Then it bounced around the family as a spare car until 2005 and I've put 60k of highway miles
since then. My mom threw out all the maintenance records before I got it but I doubt anyone got a change done between 2000-2005. Fluid looks and smells fine and it only makes maybe 40 shifts a day on my 60 mile commute and spends most of the time at 60mph with the converter locked.
Almost all my autocross runs are done in 1st gear only so that doesn't work the trans to much either.
It's too bad I don't know for sure if its the factory fill, it would be an interesting oil analysis to see, 16 years and 208,000km...
