I have been trying to put my tranny into neutral when I see I am coming up to a red light or slowing down for any reason. What I have noticed, however, is that I will put it into neutral and the RPMs will lower like normal, but when I come to a complete stop, the RPMs stay relatively high and when I put it into drive the RPMs go down to a "normal" idle speed.
Also, I have noticed the RPMs fluctuate a lot. Some days are good and some days, well... When idling or during normal operation, the revs will be at a normal speed, but on bad days, the RPMs can be close to or above two for idle and almost three at speed.
I've also noticed when switching gears, the tranny can be a little "jumpy", instead of a smooth transition into the next gear. This doesn't happen often, and I can't narrow it down to cold days or hot days, engine cold or engine hot, at speed or idle into accelerating, etc.
The bad days are few and far in between, but I don't know if these are separate issues or symptoms of a bigger problem. I do know the ATF is a little fuller then it should and I was going to change it, since I don't know when it was last changed (and we have had the car for a decent time now), but I can't imagine this to be the fix-it for all these issues. I am planning on changing the fluid on Thursday or Friday, but I was wondering if anybody had any insight on this beforehand.

Thanks!
