"Toyota teams fluid", is not manufactured by Toyota, but an oil company independent of Toyota, to Toyota Type T-III or T-IV specifications,
just as is any other transmission fluid that meets those specifications, it merely has a different brand label. The key here is to understand that transmission fluids have to meet certain performance specifications such as the Toyota Type T-III or T-IV specs. As long as the transmission fluid meets or exceeds those minimum specifications, (not all do), then the motorist is good to go. For the motorist to be certain that the transmission fluid meets the proper specifications, they can usually look on the bottle of the transmission fluid itself or consult the Product Data Bulletin for that transmission fluid. Below is the link for the Product Data Bulletin of the AMSOIL synthetic automatic transmission fluid and we can see it does indeed meet Toyota Type T-III and T-IV specifications -

Motorists aren't required to use high priced dealership supplied parts which are notorious for having a very high mark-up because of the independent dealership being a middle-man, which is the reason dealership parts many times cost so much more. So of course dealerships, (which have a well earned reputation of being referred to as, "stealerships"), are going to recommend the O.E./stock parts and fluids. Motorists can use any brand transmission fluids, oils, oil filters, air filters, brake pads, struts/shocks, etc., that they wish and as long as the aftermarket parts meet the O.E. specs, there is no problem. Indeed, many motorists desire to
improve the performance of their vehicles and use
better performing parts than merely O.E./stock parts, be it tires, brake pads, spark plugs or transmission fluid. This is why many motorists modify their cars for
better performance than the O.E./stock parts, tires, brakes, transmission fluid, or motor oils, etc. can deliver.
AMSOIL isn't some, "savior of oils", but the pioneering leader in the synthetic lubricants industry with formulating the first 100% synthetic API qualified motor oil in the world way back in 1972 and is known as, "The First in Synthetics", (tm). AMSOIL has synthetic motor oils that are indeed recommended and warranted for up to 25,000 miles and this has been so for the last 40 years. It's old hat and certainly can be taken to heart. AMSOIL has a well earned reputation for quality that is second to none in the world. AMSOIL has a black and white written warranty that is iron clad and is proudly publicly posted at their website for all to see. What other oil company proudly stands behind the quality of their products like this?
Whether the motorist you referenced followed the recommended drain intervals in this case or not is unknown. AMSOIL Signature Series synthetic motor oils are recommended and warranted for up to 25,000 miles or one year, whichever comes first, in normal duty service. If the vehicle is operated in short trip, stop and go severe service usage then the recommended drain interval is 15,000 miles or one year, again whichever comes first. So if the consumer ignored the recommended drain intervals, then that is their responsibility, not the products. To make disparaging remarks about the quality and reputation of a product without knowing all the facts, might not be ethical.

"
Automakers may not void warranties based solely on an owner’s practice of extending oil drain intervals. Dealership personnel and district managers may be unaware of the serviceability of synthetic oils over an extended period, but they
may not summarily dismiss a warranty claim based on the owner’s practice of changing oil at extended intervals. To do so does not disprove a defect in manufacture or workmanship as the immediate cause of failure. Vehicle owners may appeal to a factory representative if the dealership and district manager do not satisfactorily settle the warranty claim. Factory representatives appreciate the value of used oil analysis and do consider preventive maintenance oil analysis reports in their evaluations of warranty claims, while post-failure oil analysis is critically important to the disposition of a warranty claim. Their findings pull more weight than the opinions of dealerships or district managers".
"AMSOIL offers superior synthetic motor oils fully capable of providing extended drain service. AMSOIL is committed to backing its products, as well as protecting the interests of its customers. Therefore, AMSOIL INC. offers its customers a limited warranty. “AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company’s recommendations and instructions.” AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering superior protection for extended drain intervals.

"
The vehicle manufacturer may not specify by brand name the products you may use in your vehicle. The Magnuson-Moss Act is a U.S. federal law which states that a manufacturer may not require the use of a specific brand of aftermarket product, including lubricants,
unless that part is provided by the manufacturer free of charge. To do otherwise constitutes an infringement upon free trade. If any representative of the vehicle dealership or manufacturer informs you that you must use a specific brand of lubricant or filter, obtain a written statement to that effect and send a copy to AMSOIL INC. AMSOIL will call the entity directly to correct the situation".
"Customers are covered. As long as customers maintain their vehicles properly and follow either the vehicle manufacturer recommendations or AMSOIL recommendations, their vehicles are warranted against failure by either the vehicle manufacturer or AMSOIL INC. In the unlikely event of an AMSOIL lubrication-related issue, the AMSOIL limited warranty covers the cost to repair or replace the damaged components".
In my opinion, to imply that other brand parts or transmission fluids are not as good as the O.E./stock Toyota parts or fluids, (especially when they already meet or exceed Toyota specifications), is violating the spirit of the Magnuson-Moss Act federal law, is an infringement upon free trade and is a dis-service to motorists, in order to line the pockets of independent dealerships.
stick with Toyota teams fluid. There may be other cheaper "comparable" fluids but you never know exactly what you're gonna get. A $1 bottle of ATF vs a $3 of ATF... There's a reason they cost more.
And if you insist on using some sort of additive flush kit, go ahead. But I would highly recommend against it.
And I'm sorry, but you can't always count on the claims that certain synthetic oils are the savior of oils... For example Amsoil has some motor oil they claim will go 25,000 miles before a change... We had a customer at the dealer that took this to heart. They changed the filter a couple times but made it to about 22k without any oil changes on record. Motor seized up and threw an absolute fit when we wouldn't warranty the engine. Car only had 27k on it. Their only argument was the bottle they brought in that said it was good for 25k miles. I don't think amsoil ever bought them a new engine either...
Many of these flush additives fall under the same story. I have a ton of examples of transmissions magically coming apart very shortly after using that crap.
