The seller is AW Tec, they are not going anywhere. These likely don't have any promises behind them, but being brand new unobtainium transmissions that just as easily could have been used on the production line while building new F cars, worries should be minimal.
As for changing fluid, you won't hurt anything if done correctly. We burn this fluid up in the trucks and Land Cruisers. It's a good fluid, but too much heat can ruin it, just like anything else. With that said, the likelihood of smoking the fluid in an F is much lower than in the trucks. If we are seeing good results at this point, that being well used cars w/ 100k plus mile, imagine what kind of trans life is potentially possible by keeping the fluid at top spec. I know in the trucks, I keep it at top spec so if things do go wrong, I won't have fluid that was almost used up getting completely smoked out.

^^ Entirely New fluid flush can shock the system... from what I am hearing..
I did a Trans pan drain & refill at 50k miles.. And plan to do another one this month / next month now that I passed 100k miles
It only takes approx 3.6 qts in this process
I also measure what comes out

What I am a little confused about is that if this an opportunity for the dealer to make money, why don't they recommend or push for people to do the tranny fluid change during service appointments? I would be curious to see if they actually even DO it, or just BS you and tell you that it was done since you aren't ever going to open that thing up on your own.

Perhaps, I can feel the vehicle runs more smoothly ? Due to the fact that I had the trans fluid change on a IS250 and I could feel the difference.

Always find it entertaining when someone starts a thread about the transmission fluid and needing to be changed. Many chime in with oh yes it needs to be changed and nothing last forever. They have ZERO experience on transmissions especially Lexus transmissions. Than there are the conspiracy theorist who state Lexus says do not change the fluid knowing it will fail as soon as it gets out of warranty. If I believed this to be true I would sell my Lexus and never ever own one again.
My local Lexus Service manager who has 25 years experience working on Lexus vehicles and has been trained by Lexus said it never needs to be changed. He went to Detroit where the transmissions are made for training and asked what is the #1 cause of Lexus transmission failing. Their reply was the wrong level of fluid and the wrong fluid. Both of these are factors in one changing the fluid. I will save my money and never change the fluid and listen to the experts. Never changed the transmission fluid and never had one problem.

My 07 IS250 has about 210,000 miles on it. Within the past year, it has developed an issue with downshifting from cruising speeds. When I'm on the highway cruising in 6th, if I go to accelerate for an overtake too quickly (foot down too fast), it will miss the downshift, revs go up to max, after they come back down and it engages again there is strong a jolt that feels like a kick in the back. If I ease onto the accelerator (who wants to do that haha), I can do the overtake with no issue just a bit slower than I'd like.
