Thank-you for all the great videos you've done, I have learned so many new things about my 98' Lexus gs400, your very neat, very detailed, & your car is very nice!
@@CAMRONlamarramsey did you also install the temperature switch valve on it as well? I had to because of the sometimes very cold temps I drive in. After watching this video its very simple however the main issue I had is the placement of the actual cooler, and the hoses for the fluid, not in my most favorite spot I could've put them in but it works. lol
@@CAMRONlamarramsey did you install it bro? I have a 99sc300 aswell and I want to get this done tomorrow because my koyo radiator and mishimoto transmission cooler got here today! Do you have an ig where I can add you so you can send me a picture of how it’s installed?
Good video! Add a 3rd mount for the trans cooler to triangulate the mounting and that will help with the vibration. Cannot wait for the Valve Body update. Unfortunately I have the aristo transmission 4 speed, hopefully it is similar.
Great video. Thinking about doing this for my Tacoma so I'm watching different videos for install ideas. Well organized garage. What is the storage rack above the garage door? Thanks!
Thanks for stopping by! I had a '98 TACOMA TRD LTD and (6) 3rd gen 4Runners, including a supercharged '96 V6 5-speed with 4.30 gears, e-locker swap and a huge list of mods. Amazing rigs!

@@ForwardMomentum Thanks for the information on the rack. Looking for my oldest son. I subscribed to your channel for more ideas and info, like the oil catch can for my rig and the wife's CX-5. Thanks again
Loving the videos! I literally just drove home an 07 GS350 AWD. I'm new to the lexus club lol. Love the car and was just curious if you knew anything about this model.
Welcome! I don’t know a ton about those, but I know the 3.5 is a great engine. If I had to replace this car quickly, I’d look for an IS350, so basically the same drivetrain as your GS.
I was looking at the IS350 but with car seats it was just slightly to small for my daily. Out of curiosity, why the 400? With the 3.5 putting out more then the 4.0 and having a better aftermarket scene.
When I bought the 400 back in 2012, 350’s were out of my budget. Kinda sucks because the IS350 would dust me after 60. Then there’s the ISF...my dream car!
I didnt realize you have had the car that long, makes sense now. Yeah the F's are nice! Thanks for responding back and I'm telling the Florida scene about your channel to help get those subscriber # up. Make that ISF a reality!
Awesome vids keep up with upgrades. I had an issue with my 98' gs400. My engine is starting to die out when I'm at a stop sign and traffic light.... has this happened to you or would you know what this problem is?
It could be so many things. First thing I would do is a thorough check of the entire intake system and all vacuum hoses. Buy an OBD scanner and data logger like the Veepeak WiFi adapter. Run the Car Scanner Pro app and check your fuel trims. I’ll be filming a fuel pump video next. It could be that for you, but definitely narrow it down first.
You can’t go wrong. There wasn’t a bad year with major issues. They are all tanks. Maintenance records or proof is key. The wheels are off a 2016 GS350. Thanks for watching!
i purchased this same catch can and stuffed the bottom full of steel wool, but upon installing it into my 2GS300, it made my car run funny and made weird noises like my valve was doing something funny and sound squeeky so i uninstalled it... curious if i install it incorreclty
Double check if you ran the catch can out line before or after the throttle body. It should be attached before the throttle body (closer to the air filter).
thanks for the video Christian. I guess i don’t need a thermostatic module here in FL? So if i’m not going to use the thermo module then i tap the line first that was dripping and run it to the Top connection of the cooler and where would the bottom connection of the cooler go too? thanks.
Np. I guess it depends on your low temps in winter and if you will ever take the car anywhere cold. A lot of people run a cooler with no thermostatic valve at all. If you do, you would run that soft line out of the OEM radiator to the cooler by using a barbed 3/8 coupling (that package I only used the hose clamps out of is perfect) and 3/8 hose. Then cooler out back to trans by attaching to that hardline. Same as my vid shows.
Forward Momentum. thanks. I don’t think i’ll use the thermostatic valve. I’m just confused on where the line coming to the stock cooler goes? Then the top external cooler line goes back into tranny (the one you pulled first that was leaking). sorry for the noob questions.
I understand. I had to draw it out, LOL. So just concentrate on the same line I unplugged in the vid. The line on the left, which feeds the OEM cooler just stays in place. Disconnect OEM soft return line from its hardline connection. Fluid will spill out. Add a coupler to that OEM soft line and more 3/8 hose. Run that to the top of the new cooler. Connect more new 3/8 hose to the new cooler on the bottom (out) fitting. Run that all the back to that original hardline you disconnected from. Hose clamp everything. That’s it!
When i go WOT 1st to 2nd it shifts good but 2nd to 3rd the car hits the rev limiter for like a 1 second and then kicks into 3rd, 4th gear is also harsh WOT, but smooth when cruising, could my transmission be going out?
@@ForwardMomentum previous owner changed fluid, level looks good and he also changed the filter, i just hope it wont leave me stranded one day, it shifts okay for the mileage but i have a feeling its near the end of its life
Probably right. After all, these are 20+ year-old transmissions. I was pretty bummed when mine started to go out, but it really pushed me into the manual swap. 😎
It’s really up to you on how you want to do it. It’s pretty tough to fill the cooler unless you have a good way to hold the fluid in (assuming you can even get it in there). That said, note the capacity and line capacity and add ATF accordingly. When you start up the car, let it run for a bit so it cycles the fluid. I personally would add the fluid after just to keep the mess down.
It’s so subjective. My taste may be totally different than yours. My suggestion is to watch all the vids you can of the GS3. I personally like it loud. In fact, mine is too quiet as-is and I’m considering going to bullet race mufflers to still pass inspection, but still be loud.
No worries. There isn’t one answer that fits all. There’s an ideal operating temperature for the AT, so the cooling surface area depends on your climate and driving habits. A reputable cooling company like Mishimoto can probably offer you a better answer than me.
@@ForwardMomentum As you know im from Uae so weather in summer is so hot and as GS400 owner i drive speedily add on weather temp thats mean i have to install T cooler..what if its from china? It handle it or no?
You need vacuum for it to work properly. If I vent to the atmosphere it will stink, spew oily mist all over under the hood and the car will fail inspection.
I don't know, every time I change my oil I take the oil out of the catch can and it has a good amount, if it's working for you that way, then leave it. I have turbo car's I wouldn't want nothing back going to my throttle body, Cause that oil goes in through the heads and you accumulate oil in your Valves.
I hear you. But that’s exactly why I did this mod. The baffle plate collects and drops the oil and contaminate-free “air” goes back into the intake. This is beneficial because the octane value is raised. I’ll keep an eye on my TB and see if anything gets on there. So far so good - this method is working well.
@@ForwardMomentum thank you FYI I took your advice on the vavale body modification so far i noticed a huge difference in my car I wanted to put the trans cooler next but wanted to know more info before just buying one keep up the work 💪
@@ForwardMomentum oh bro it was easy just took some time me and friend just watched your videos like 5/6 times lol and follow everything you did I have the tools im just very happy someone iike you is actually taking the time and showing people how to make this great car last forever
@@ForwardMomentum I just been stuck on this trans cooler because you forgot the part name/# but I got everything else in that kit just not the cooler every time I look it up on Amazon it says it don't fit my car and that's there non of them for my car but ik that's bs because you got one and I know other people who got them but idk do you have to just rig it up or something lol
The only reason I didn’t link is because I received this free from the seller of my valve body upgrade. It was used and there are so many options out there that I wanted to encourage people to look at options that might suit their needs better. For example, some may want the entire thing in the air flow, so they would want to go with a longer, skinnier cooler.
@@ForwardMomentum on another subject, not sure if you know anything about this. I have a valve body in my infiniti, there are refurbished ones I can get for half the price, i was told they have to be flashed to the vehicle? is that correct

Does it matter which way you mount any trans cooler? Looking at mishimoto options
If you’re asking if there’s a “front” and “back” no, it doesn’t matter. However, there’s an “IN” and “OUT” for the lines.
@@ForwardMomentum ok and one last question how much fluid did you put back in? Did you prefill the trans cooler? Or just fill the trans with fluid
It’s really up to you on how you want to do it. It’s pretty tough to fill the cooler unless you have a good way to hold the fluid in (assuming you can even get it in there).
