Synthetic fluid!

My wife has a 2007 Toyota Camry. Never has been changed per owner manual.

My Cummins powered motorhome has a 50,000 mile change out IF if has synthetic fluid.


Today is my personal best for most consecutive days alive.

I can understand your nervousness about it but I have two older vehicles with sealed transmissions, an F150 that has been used quite a bit for trailer towing and 150,000 miles on the clock, and a 2011 Kia Optima with about a 160,000 on the clock. No transmission troubles from either one so far. I did recently get the fluid changed in the F150 as a precaution.

My 2016 F150 only has about 61,000 miles on it but shows that 33,000 of those miles where pulling a trailer over 10,000lbs. And that is not the only trailer that it has been used to pull. If I am not hauling or pulling I generally drive something smaller. I intend to do a transmission fluid and filter change on it soon out of caution. It doesn't seem like it is going to be that hard. You just have to do everything from underneath the vehicle. That makes checking and adding fluid a little more challenging.

Filled for life is great for trans shops and dealerships. Fluid is cheaper than a trans. At the very least drain the fluid and refill it. I’m sure the fluid is pricey, but again it’s better than getting stranded because you didn’t change the fluid!

Obviously older but on our 2008 F250, our local mechanic refused to do it when we asked. They had too many times when they changed it and 2-3k miles later the transmission crapped out.

Currently around 215k miles with no issues, so not fixing what isn't broken. I might think differently, if we had overheated the transmission and cooked the fluid.

In 1986 I had a AMMCO Transmission with their lifetime warranty installed in my 73 Blazer. One of the main features I liked about it was that I no longer had to do any maintainence on it. I just had to take it in every year for them to look at it. At first they were changing the fluid and filter, but that soon stopped. The yearly check consisted of them driving it around the block, checking rhe dipstick, and trying to sell me additional serfvices. I did not care, if they actually serviced the tranny at all. If it failed, they had to fix it, About 15 years ago, they told me that the tranny fluid and filter needed to be changed. I told them to go ahead. They told me how much it was going to cost me. I told them to read my warranty. After much hemming and hawing and some phone calls to corporate, they honered the warranty and did it for free.... And then told me that it did not need to be done very often, and that the Lifetime warranty I have is not like the one they offer now. They have not changed the fluid/filter since. And they have really backed off on trying to upsell me other services.
If one thinks about it from a mechanical mindset, tranny fluid is not like engine oil.There are no combustion contaiminents finding their way into the fluid.And the fluid really doesn't wear out. So long as it doesn't get too hot, it can last forever.

Except there is no place to put new fluid in!

Previous next door neighbor had a new Toyota or Nissan truck. Drained the transmission fluid on his "usual maintenance interval." Went to fill it. No dipstick! Crawled all over the transmission. No fill plug anywhere on it! Sealed from the factory.

Suffice it to say, he instantly voided the warranty. Had it hauled to the dealer. They could not put fluid in it. As I recall he had to pay for a new transmission to be installed. All his fault for not following directions.

There’s about zero chance that a fluid change voided the warranty and zero chance that it’s not able to be filled. Just different methods on different vehicles. They don’t fill em by osmosis at the factory.
Yes trans service intervals have gotten much longer as both transmissions and fluid has gotten better.
And maybe most of them will last 250k miles or whatever. But there’s no magic that keeps the fluid “like new”. And especially if working it hard or planning on keeping it long term high miles, a reasonable service interval is a good thing.

Wow! That is an interesting and expensive situation. Reading that little book in the glove box is getting more and more important.

Transmission being "filled for life" is not a new thing. That has been the "spec" in many vehicles for over 20 years. I am sad they removed the dipstick tube (there is still a very short dipstick you can get to from underneath). The color and smell of ATF will tell you if you have a problem. Of course, by then, it is probably too late.

Almost all modern transmissions have a temperature sensor. This is the most important thing to be monitored.

If you are still not happy, ask to see the official "severe duty" maintenance schedule. Or drop the pan (but not the filter) every 25K-50K, measure what you took out and replace it with the exact OEM ATF.

My 2022 F150 came with a "Cliff Notes" edition of the owners manual. The real one is on line, or you can request they send one to you.
