Is it time to change your transmission fluid? How do you know when to change your transmission fluid? These questions will hopefully be addressed in this article.

How Often Should You Change Your Transmission Fluid?
There seems to be a lot of misinformation about how often you should change your transmission fluid. According to the article “Do You Really Need to Change the Transmission Fluid?” by Rick Popely,
“The manufacturer’s maintenance schedule for many automatic transmissions doesn’t call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and it should be done at least every 50,000 miles. Manual transmissions may be on a different schedule, so it’s best to consult the maintenance schedule in the owner’s manual.
Like other vital automotive fluids, transmission fluid deteriorates over time. Hard use — such as frequent stop-and-go city driving, hauling heavy loads, trailer towing — will accelerate the deterioration. That kind of driving raises the operating temperature of the transmission, and heat puts more strain on the transmission and the fluid, which helps facilitate gear shifts, cools the transmission and lubricates moving parts.
If you do a lot of driving under high-stress conditions, you should check the transmission level more often and have a repair shop check the condition of the fluid. Transmission fluid often is red but can come in other colors, and as it deteriorates it tends to turn darker. It may also acquire a burned odor that could indicate it needs to be changed or that the transmission is developing mechanical problems. Another indication it needs changing is dirt or other debris in the fluid. When you take your vehicle in for an oil change or other routine service, the repair facility may urge you to pay for a transmission-fluid change or flush. Even if they can show you that the fluid is darker than original, that might not mean you need fresh fluid right now. Step back, check the maintenance schedule in your owner’s manual and see what the manufacturer recommends before you decide. This also will give you time to price shop.
Many repair shops use flush systems that force out the old fluid and pump in new fluid. Though that sounds good, some manufacturers say you shouldn’t do that (Honda is one; there are others), so you need to know this before you agree to a flush.”[READ SOURCE]
