YES, another transmission thread but only for information
Hello fellow LS fans, Im just here to give a little info for some that might not think its needed.
For the last couple of months, my 2007 LS with 160k miles has been acting like it cant find gears, sometimes it would slip and I could hear what I later found out to be the pump which sounds like a power steering pump when its low on fluid. I decided on doing some reading and came to the conclusion that it was more than likely the transmission oil filter. Headed to the local Lexus dealer and picked one up along with the Oring and 5 quarts of fluid to do the job myself. I wont get into how its done since there are already a few writeups on this procedure. But what I will say is that the filter was indeed dirty to the point that when I removed it, about 1/2 quart of fluid came out of the hole and I can clearly see that the filter element itself was nothing like the new one. Took all of 60 min to do the entire process including the fluid level and now the car runs as good as the day I picked it up 14 years ago.
Long story short, for those that thing this fluid is "lifetime", while it can possibly be, the filter is not. So do yourself a favor and get in there and change it and some of the fluid. If youre having tranny issues and have never done this, try it first.
PS:, I plan on doing a few of drain and refills in the coming months to get some of the original fluid out of there.
Also, Id read that its recommended to do a transmission relearn when new fluid is added. Unfortunately, I have Techstream but dont have the proper cable to do so.

It is a well established fact that there is no such thing as forever transmission fluid. Replacing a transmission filter while doing a transmission flush or every 60-100k miles is a must.

Heads up for AWD cars - dropping the pan to replace the filter is complicated the crossmember for the transfer case. Getting to the rear pan bolts requires a very short socket and lifting the transmission off the crossmember to get enough space.
Also if your car spent time in the rust belt the transmission bolts can seize to the pan and break when you try to remove them.

I personally recommend removing the cross member while supporting the transmission with a jack. It makes the process much faster and easier. My transmission pan bolts were rusted and one broke. I believe, I replaced all of them with brand new ones. It is being a while since I did it.

I’ve been wanting to do this and my local dealer told me we do t do flush service , I said drain and re fill he said, we can’t do that. So I’m lost on where should I go to get this done cuz I feel my transmission holds a gear for long at high RPM when I do push the car to its limits here n there.

Many here recommend either Toyota or an independent shop with Japanese car experience. Search on Yelp for reviews and names. You're seeing that some Lexus dealers lean toward newer cars for repairs and often won't do small jobs or repairs vs replacement. With high overhead, they need to keep it high dollar.
