I checked the transmission today on my 1987 2-WD van today and noticed the fluid has turned from a red color to a slightly brown color so, I want to get it changed but, I have read many posts here over time that says that when others have changed the fluid, they end up having transmission problems.

Mine is doing great and am sorta afread of doing the fluid change. What the the pros and cons of serviceing my transmission? should I just change the fluid and not disturb the filter or go ahead and change the filter and fluid and hope for the best?????

Thanks in advance for any information on this.
