Link to the ECU that I bought that matched my original ECU:

Other Lexus GS300 ECU's for 98-05

MAKE SURE THE NUMBERS ON YOUR ORIGINAL ECU MATCH WITH THE ONE YOU BUY!

My 2000 GS300 had the same p1755 code with hard shifting. I got the ECU and the check engine light is off! Drives like a dream again! Thanks bro!

[beiyzzz]

Thank you so much man, I swapped my ECU and the check engine cleared immediately and it ran a lot more smoother, couldn't say thank you enough!

this video is the truth What THEY DON'T TELL YOU ABOUT LEXUS CARS AND WHY THIS VIDEO IS THE TRUTH.... YOUR LEXUS ECU is actually LINKED to your transmission so if your like me you thinking this video doesn't make sense but that why this video WORKS there is another person on YouTube a LEXUS ECU company that breaks down why changing you computer makes sense....I got ECU from Junkyard and got key to it and like video says. SHIT FIXES EVERYTHING P1755 GONE this video was only life line I had THANK YOU SO FUCKING

[oscarvillegas]

I have a replacement key and it's not a key fob, i've been wanting to get a key fob for my 00' gs300 while fixing p1755, will cutting the key that comes with the Ecu to fit my car be fine?

[senseigelatosz]

Will this fix the doors not unlocking when you try to unlock it wit the key ??

[digitlongname]

can someone explain what is going on in the example videos? starting at 3:56 -4:21 ? to me it just looks like its shifting at a lower rpm but how can i tell whats its normal rpm to shift at

[anthonyramirez]

I have a 2003 Lexus GS300 that won’t turn over nearly replaced everything you think it could be a bad ECU??

[oscarvillegas]

I own a 99 LEXUS GS300 and i too got the p1755 code but only for poor electrical circuit, my car drives everywhere only thing is my rpms are slower and so is my shifting im HOPING its just my ECU , based off of other gs300 i dont think my solenoids are locking or worn out, i took it to a transmission shop and they tried to tell me that i have 3 codes when i do not i only have the p1755 POOR CIRCUIT I feel like there trying to make me do a whole lot to my car they quoted me without even dropping my pan how is that possible when it could just be the ECU my transmission isn't slipping and they also said my fluids are burnt or contaminated the fluid is still its natural color 🤔💯so idk im not trying to waste money on dropping the transmission pan when there's nothing wrong with the transmission itself only poor power or electric circuit all connectors look good and everything leads to new ECU PLEASE COMMENT WHAT YOU THINK

[DanielSanchezzz]

how long did the shipping take cause it’s been over a week and i haven’t gotten a tracking number or anything 😓

[jermainevalenzuela]

Is there a way to get the ECU numbers without pulling out my old one?

[scottleary]

this is a great video thanks for posting this. I have a 1998 GS300 with a bad ECU. I know this because the immobilizer keeps locking up and preventing the car from starting. I took it to my local shop and they confirmed it's a bad ECU. So, they want to charge me $1200 for a new ECU not to mention $600 labor for installing another one! No way I am doing this. My question is - if I order my own ECU from module mechanics swap it out, the car won't start with my old keys right? I can actually take the key they send me over to my locksmith and have them cut a new one right? I have a guy who will do it for $10 down the street thanks again

[tregs]

this isn’t a problem on the gs400 is it?

[JaredBennz]

Long shot you’ll respond but did you experience any jumping while slow acceleration I got the same code Js wanna make sure it’s the problem

[anthonybarksdale]

I'm getting the same code. I have a 1999 GS300, but my transmission had a fliud leak due to the gasket failing. I let too much leak out, i felt a couple of hard shifts in 1st gear. After a little driving i turned off the ECT power to normal. 10 minutes later my check engine came on. I went to autozone and the only code is P1755. Since then, i added transmission fluid from Toyota. The car doesn't kick anymore, but the check engine light is still on and my first gear doesn't rev up like yours did in the video to 6000+ rpms. I'm going to try replacing the SLU solenoid and resealing the transmission pan. If that doesn't work, I will then try replacing the ECU. Did you disconnect the battery after replacing the solenoid? Did you ohm out the solenoid to see if it was bad? I have 540, 000 miles on my lexus and I have never had a transmission problem. Thanks for posting this video to give me more options to solve this.

I Have the code P1755 on my 2000 Lexus GS 300 I swapped 3 solenoids and the check engine light is still there, also I’ve Noticed My 3rd gear Feels like it’s not Working When downshifting From 4th to 3rd or 2nd to 3rd. Do You think If I order a ECU & it’s not the Problem You think they accept Like a refund?

[beiyzzz]

Hey man I just ordered my new ECU, do I need to program it or is it plug and play?

[scottmoya]

Dealing with the dam stuff as we speak o got another transmission put it in and the same dam code pop up that like one in a million so I just got a ecu I think that’s what my problem is

[KING_TOPGSlope]

When u installed the ecu u didn’t have to call like a dude that programs the key ?

[rubencapeles]

Have the same code and runs like shit to me lol how do u know for sure it's the ecu
