When should you change your transmission fluid?

After driving my 99 Chevy Van in the blistering heat of the Arizona desert for the past 6 years and 85,000 miles, I became concerned about the ATF in my 1,300,000 mile original transmission that has never been overhauled.

Prior to moving to AZ…I lived back east.  Had a delivery service driving 8-10,000 miles a month.  Was changing my Amsoil ATF every 150,000 miles or about every 18 months!  When you drive over the road…you can go much further
on oil changes…if you’re using a high quality synthetic oil like Amsoil. 

I reached out to the GMC dealership about ATF fluid getting old.  They recommended changing it every 50-100,000 miles. 
Amsoil Tech department said the same thing.  Most Techies will tell you, go by the owners manual. 

What if it says change the ATF every 100,000 miles and six years later you’ve only
driven 85,000 miles?   Should you be concerned about the ATF breaking down or getting old?

Your Transmission Is The Weakest Component Of Your Drivetrain

From my experience over the years, most folks are more concerned about their engine oil with little concern about their transmission oil.  Guess what?  The transmission is normally the first component to drain your wallet.  It’s the weak link of the drivetrain.  We’ve all had to replace one and they’re not cheap.

Since no one could answer my question, “does ATF get old” the thought came to me …  Order an oil analysis kit from Amsoil along with the Amsoil transmission fluid plus a Wix transmission filter,  make an appointment at the Dealership to do a transmission flush and catch a sample of the Amsoil ATF when they drop the transmission pan.
(Order your oil and oil filters easily by looking up your vehicle, and shop by your vehicle’s make and model.)

Catching A Sample Of My Transmission Fluid At The Dealership

It had been almost 6 years since I had changed the transmission fluid in my 99 Chevy van.

In July 2018, I made an appointment at the GMC Dealership to flush the transmission.  The odometer reading was 1,312,400 miles…still original transmission…never been overhauled!

The technician allowed me to observe the entire flushing sequence.  Never done that before.   When he dropped the transmission oil pan, I had a 12 oz glass jar I used to catch a sample of the oil.   I later transferred that into my analysis kit sample jar.

I Was Anxious To See What The Magnet Looked Like

I could see through the glass jar…the oil was red and clean.   I got to take a look at the bottom of the oil pan and most importantly…what did the magnet look like.

Why? Metal shavings…that’s what the purpose of that magnet is for…is to collect them.   And if there’s lots of them…it’s an indication your transmission is experiencing significant wear and a potential repair looming in the near future.

There was a small amount of dirt particles close to the magnet at the bottom of the pan.  The magnet had a light coating of fine dirt particles…but no metal shavings.  Conclusion…very little wear was taking place inside this Million Mile Transmission.

Even the technician commented on how clean everything was.   And me…I was bubbling over with enthusiasm once again at “how remarkably tough” the Amsoil transmission fluid really is.

The technician submerged the oil pan in a special cleaning machine to thoroughly clean it.  Dried it and applied the rubber transmission gasket. 

He removed the old Wix Transmission filter and snapped in the new one.  Installed the oil pan and then added six quarts of the Amsoil ATF into the transmission fill tube to replace the ATF that was in the oil pan.  The transmission holds 14 quarts of oil.

NOTE:  If your transmission has a transmission oil filter…insist that it be changed whenever you change the transmission fluid.  Some dealerships will try and persuade you not to drop the oil pan…because it will take longer to change the oil.  And will cost you a little more money in labor. 

By the way…just dropping the transmission oil pan and adding 4-6 quarts of oil without flushing…you’ve left half the ATF in the converter.  So your adding good oil with not so good oil.  The good ATF fluid becomes diluted and will not last a normal transmission oil change of 50-100,000 miles.

Flushing Your Transmission With Amsoil ATF…May Make It Almost Immortal

He started the engine and let it run for a few minutes.  Poured 18 quarts of Amsoil ATF into the flushing machine.  He inserted the flushing machine tube into the transmission fill tube and slid it to the bottom of the transmission oil pan…punched a couple buttons on the flushing machine and the ATF fluid started flowing into the fill tube.

It probably took about a half hour to complete the flush.  I normally only used about 16-17 quarts of the ATF in the past.  However this technician suggested putting 18 quarts into the flushing machine to get a thorough flush.  So I ended up using 24 quarts this time.

I was told by a technician at the Chevrolet Dealership back in Ohio several years ago…you cannot remove 100% of the old ATF by flushing.  However he said you can replace at least 90% of the ATF by flushing.   So I figure I got a really thorough flush with 24 quarts.

What A Surprise When I Saw The Oil Analysis!

Filled out the paperwork and sent it along with the oil sample to Indianapolis, IN.  About a week later, I received my results by email.  What a pleasant surprise.

In the upper right corner of the report there’s a scale from 0 – 4 giving you a quick snapshot of the condition of your oil. 0-1 is normal.  2-3 is abnormal.  4 is critical.  It read 1 or normal.   There’s a section in the report for comments.  They said, “the viscosity was slightly low at 5.7.”  Amsoil ATF viscosity unused is 7.5.  They went on to say, “there’s no immediate need for maintenance action.”  Man I was happier than a pig in slop!

After 6 Years and 85,000 Miles…Amsoil ATF Didn’t Break down Or Get Old!

At 1,320,000 miles (as of January 2019)…it appears the “original transmission” in my 99 Chevy van…can blame the Amsoil synthetic transmission fluid for this remarkable achievement.  If this story does not cause you to want to change all your vehicle fluids over to Amsoil…then your wood is wet!  More importantly…the fella in Wisconsin that drove his 91 Chevy pickup truck 1 million miles…went through 5 transmissions! Estimated bill: $17,500.

Now that’s what I call a “Thousand Pound Dog.”  That’s a big deal when you can go over 1 million miles without having a transmission breakdown!

If you want to have peace of mind about keeping your vehicles for 500,000 miles “PLUS”…I have
proven that the Amsoil synthetic fluids will make your vehicle almost immortal.

It only takes 5 minutes to order online or by phone…and have the product shipped to your doorstep in 2-3 business days. In 20 minutes…you can have your dealership or local repair shop change your oil…and add the Amsoil synthetic oil and filter to your engine. And just that quick…you’re up and running. And that’s not all. The best is yet to come.
