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

Finally got the caps changed in my Celsior, not done by myself but by a pro. It took about 2 hours changing all 9 of them, we took our time to do it right. Looks like its factory done !
The ecu is still learning new settings, but the car is allready a lot more economic, and the transmission shifts smoother by the minute.
Thanks a lot for all this info on here. A big 10 for Yamae and Cowboy

Congratulations on your success.
Once you mentioned that you were happy with the ECU for a 96 changing from your original 95. There was no more unexpected engine stop after the high speed run and also there was some performance improvement.
It seems to me that you now have additional better results. You are another happy owner who proved that our recommendations revive the car.
The replacement is a kind of must, I'd say.
As far as I see the thread "Have you done the ECU capacitor fix?" by RA40 / Mike, many owners are still using original capacitors and not enjoying the original good performances of his/her LS400 or Celsior.
I feel sorry for them not knowing the fact that the car runs much better.

Hi Yamae,
Yes im very pleased with the results. I was allready very content with the other ECU but with the new caps it feels like new. The car is even more powerful, and runs very smooth.

If we could only get most owners of LS400 to realize that this is a huge problem that all LS400's will eventually have, it is like 90% of owners are skeptical, but if they understood electrical engineering, they wouldn't be!

my cruise stopped working with the failing main ECU, as well as speedo issues
I have not heard of any issues with the cruise ECU itself though

I got all the maint. up to date and runs great! That's the only thing not working is just that so thought I would ask. I will look into it further when I eventually get the motivation.

ECU or TRANSMISSION
Hi,
thats a great thread up here !!!
I have a small problem with my transmission. It shifts ok when I drive slowly, but when I push more on the gas to accelerate more, car raises the rpm more, doesnt accelarate that much and kinda slips...shifts hard from 2nd to 3rd.
I was always thinking I had some trany problem, but it seems like it might be a ECU.
changed the oil in trany 2 time, didnt help.
Am I right about the ECU??
Anyone had same problems??
No code, no CEL ... just goes hard from 2 to 3 when going fast.
LS400, 1998.
thank you !!
btw, can someone give a number for this ECU. I dindt find it, cuz there are kinda many of them

Yes you should. Especially when the capacitors allready have leaked, you have a lot more work on it. Better replace them before that! Don't try to replace them yourself, it's not as easy as it looks.

"All LS400's" as in 90-97 or "all" period? I definitely have no time to address such a repair so I have shifted my focus to 98-2000's. If I will have to do it anyway, then I should be looking back at the earlier models, save some $ and have some pro do the soldering?

It should be instructive that the person who understands this issue better than anyone, Yamae, has done his caps and he owns the 98-00 generation

Well, I guess the most important step right now is to get a car first and then worry about the caps.
