All my crazy Lexus issues SOLVED!! (ECU-leaking capacitor)

I re capped my ECU with the ones mentioned but apparently not much has been improved. Car is still not daily ready, Got speed sensor 1 code (changed but popped up again), solenoids 2 and 3 (getting solenoid 1 and 2 replaced today, going to buy solenoid 3...so expensive for a solenoid). Cluster is still all wonky, could bad capacitors in the cluster affect speedo/odometer/tachometer/lazy temp gauge and could bad cluster affect the transmission? I'm pretty much chipping options away and hoping one of the options fixes the car.

It looked in perfect condition, Will post pics soon for visual inspection. Mechanic changed shift solenoids 1 and 2 today, fixed SL solenoid wiring (apparently it was bad). He didn't check speed sensor but I replaced it and still popped up so probably could be wiring also. I'm gonna pick it up tomorrow to test it.
EDIT: here are the pics.
This pictures shows 3 10mf caps when there is 2 10mf and 1 100mf, shop fixed it after I told them. 100mf cap was supposed to go in between the black pieces.

Still, many thanks to Lone Star Cowboy
Now, correct me if I’m wrong, but there is zero difference from a NOS zero mile ECU and his “perfect core” that he squirreled away. He is also not the only person that has access to the capacitors since all the sources have been listed here. He is also not the only person doing the repairs in the US using those “Super capacitors”. What he is doing is taking advantage of someone that doesn’t know about this forum and bs’ing them in order to get a higher price. Two things I do know, business practices and sales tactics. What he’s doing is pure shady tactics. This is the same type of marketing that telemarketers use on cold calls to someone that hasn’t heard of their business. Like I said, glad he put up all the info, but I’ll go local for my repair.

As I said, I thank him for figuring out what the source of many issues actually was, which is the caps in the ECM. Yamae I can garauntee played a bigger hand in providing info for various ECM models by year, and probably for locating the correct capacitors, but I can’t do business with someone that would blatantly lie like that to a potential customer. First off, he is not the only person in the US that does the repair. Second, he is not the only person that can acquire the capacitors since the parts numbers are listed here and links to where you can order them from. So yes, thanks to him we know the source of the issues. Not forgetting that since he started this entire thread almost a decade ago, but I don’t trust anyone to work on anything of mine that will straight up make false claims about anything.

Thank you (and the guru) for this information. My '93 LS400 just started many of those symptoms. Two questions:
1. If the problem is so common in early cars, why hasn't there been a recall?
2. Board fixing is beyond my skill set. Where/who can you recommend to replace the capacitors in my ECU?
Thanks, Jim
