bad tranny fluid?
My 94' A4WD (99,000mi) aerostar transmission has been giving me greif by shifting hard and whining excessivly. I checked the fluid levels and they appear to be in the proper zone. I noticed when I wiped off the dipstick that the color of the fluid was brown/black but it did not smell burnt. Could old tranny fluid cause the problems im experiencing and if so what is the best way to change the fluid?
Thanks

I had the same problem in mine, changed the filter and ran a transmission flush on it. A trans flush is really the best way to change out the fluid, you only get maybe 1/3 of the fluid out with just dropping the pan and changing the filter.

I was going to change fluid in mine but some guy told me that if the fluid has never been changed and I doubt it has that he knows of people that had failers after the change. Do you all believe that? I am talking about high milers.

It can happen, but I've also done it to my own high milleage cars. I've never had a problem with my own 115000 miles or so, but on customers cars at work we make them sign a waiver about that problem if they're past 70,000 miles without a record of a change at our store. The cars I've seen fail after the service were close to 200000. I'd do it if I was you but be aware that there is a risk. Best of luck.

Just dropping the pan and changing the filter is probably safer than running a flush but there is still a risk to it.
