Transmission problem '99 LS400

I recently decided to use a gasket instead of the FIPG which was applied by a dealer last time when the pan was dropped a few years ago. The ATF has been leaking little by little since then but the dealer could not fix it. I don't trust the FIPG applied by an unskilled human. I consider that it should be applied by a industrial robot which is adjusted precisely.
You will find how I dislike the FIPG seeing photos below.

The car is 98 Celsior 94k miles. Here in Japan we are normally forced to stop and run very often like you drive in the city and the damage to the AT must be more than yours. Other than the ATF leak, I did not have any particular problem with this transmission although it had this much of unwanted gunk.
I think the strainer has been doing a good job. But it is just a mesh and smaller particulates must have been passing through it and circulating. I can see some of them at the bottom of the pan but most of them were small particulates from the clutch. Those magnets were catching some of iron materials and you can imagine the amount of those.
Doing the job myself, there were some other interesting experience other than particulates but my limited English skill prevents me to write the whole story well enough. If you are interested in them I will try to report consulting the dictionary.

You should always warm your car up if it's 40 and below. If you don't, you're going to be wearing out your internals of your engine faster. The cold makes lubricants Thickened up.

I have a 1998 LS400 with 137k miles now. Cold operating temperature has similar effect on my transmission. I'm not too worried about it because it completely goes away when engine is warmer. Even if I park the car for a few hours then drive again. I may change the fluid at some point as precaution maintenance. I only change my oil with full synthetic Mobil-1 oil. The Lexus dealer uses this oil for their synthetics.
