TOYOTA / LEXUS STAGE 1 Transmission Mods & Maintenance

MY STORE: forward-moment...
LEXUS GS400 shown with A650e transmission. Stage 1 should be applicable to any TOYOTA vehicle equipped with the A650e transmission such as GS300, IS300, etc. Please verify all instructions to your specific vehicle!
*NOTE: I will be installing a modified valve body for STAGE 2; if you plan to install a modded VB, I recommend waiting for the next video and then combining STAGE 1 and STAGE 2 together, at the same time.*
For faster shifting and improved reliability, I recommend:
STAGE 1
1. Transmission Cooler -- (video: • External Transmission ... )
2. Line Pressure Dial set to III (most pressure)
3. Trans Strainer ("filter") Replacement
SUPPLIES NEEDED (#2 & #3 above)
~3 qts TOYOTA TYPE T-IV ATF
Duralast Strainer Kit, P/N TF634 (includes strainer, 3 gaskets, 1 trans pan gasket)
Transmission drain plug crush washer (motor oil drain plug size will work too)
TOOLS
Jacks and stands
Gloves
Safety glasses
Basic hand tools
Ratchet extension
Torque wrench (in-lbs)
Drain pan to collect oil

This must be the best kept gs400 on the planet.

[@taintedsasquatch398]

Or he’s not from the northern part of the country, I’m in Jersey and if you find a non rotted car you found gold.

[@soulsurvivor420]

Old video, but I'm surprised I didn't see in the comments, the WIX transmission filter kit for this car is really solid. I got that for my '04 GS430 and run Castrol TransMax ATF (import multi vehicle type), and I've had zero issues. Doing the valve body adjust today, it's been on 2 (the middle setting) for a while so I'm sure I'm safe to dial it up to 3.

[@mikeysl379]

Thought about doing this. Now I have a video to go by. Nicely done

[@Diego-dv2rg]

Wow i actually didn't know about that dial setting. Thanks a lot, as always a good video

[@MikePlacer]

great timing Im thinking i might try to save the money and do this my self

[@soulsurvivor420]

Also, just to add, for that cross brace that goes over the lip of the transmission pan, I used a 1/4 drive ratchet, short extension, and normal sized socket to access it. Had to use my fingers to get those two screws all the way out though, and also to start them. The other 2 on that lip (the corner ones) I could get to easily, but the two middle ones were a pain until I grabbed my little 1/4" ratchet, extension, and socket

Oh that was great seeing the valve body assembly opened up! Thanks. I wish you had shown the shift selenoid A, B, C etc. If you could point them out I would really appreciate it. That is if they're actually reside there. Thank you very much.

[@drrock5356]

My '00 GS400 secret shift dial was set on the lowest (full CCW rotation) setting! I just set it to high (full CW rotation) during an AT fluid and filter change. I sure hope me and the transmission like the new setting, lol!

[@ForwardMomentum]

Crazy! You should be able to feel the difference, especially at around 75% throttle input through the first 3 gears (not sure why but that’s where I really felt the difference).

[@drrock5356]

@@ForwardMomentum Damn, last night when I carefully put the transmission pan back on, full of gooey FIPG, I "missed" the fill spout connection. It took me about 4 hours today to unbolt the upper fill valve tube, insert it into the lower fill tube, and get the bolt back into the mounting flange and tighten it. I also stripped a threaded stud removing the left cat, in order to get access to the nightmare bolt, lol!

[@ForwardMomentum]

Dr Rock we’ve all been there. I hate when stuff like that happens. Seems like you have a good attitude though!

[@drrock5356]

​@@ForwardMomentum Lol, I'm trying to keep my attitude toward the GS400 positive. She just came down off of the jack stands after 5 weeks of repairs and maintenance, which included new engine mounts, new (used) rear diff (OG diff blew up!), new carrier bearing, new tranny fluid/filter/shift setting, and new exhaust gaskets. To fix the P0440, I dropped the gas tank and installed a new vent valve, over fill valve, tank-to-charcoal canister tubes, and a new gas fill tube. The test drive revealed that the new (used) rear diff works, and the engine idles smoother and “stays put” when the tranny engages. But there’s a light yet significant drivetrain shudder/vibration during acceleration between 20-30 mph at medium power. And when I parked and got out, I could smell gas from the rear DS wheel well. I suspect that moving the shift setting from “1” to “3” is causing the 20-30 mph vibration, so the pan (and 6 qts of fluid) will be dropped again, so I can access the shift pressure dial, and turn it back to “1”. The gas tank must also be dropped again, which means removing the exhaust, heat shields, driveshaft, and rear diff, which I just reinstalled, so that I can access the tank lines and charcoal canister. I blame 20 year old rubber, field mice, and the massive burnouts the previous owner enjoyed doing to my precious GS400.

[@ForwardMomentum]

@@drrock5356 oh man! That dial should have nothing to do with vibration. That sounds like the driveshaft to me. Seriously, I wouldn’t even bother with the dial; I promise you all it does is increase line pressure a little and that’s it.

[@MissouriMatthew]

@ForwardMomentum is there any reason i would NOT want to change the dial on the valve body of the transmission to the third setting on a 98 Ls400?

[@ForwardMomentum]

Yeah, if you like soft, flared shift action. It gets just a smidge more firm with this mod.

[@MissouriMatthew]

​@ForwardMomentum I changed the pressure switch to the third setting on the transmission, and it works great! Thanks!

[@bartw4031]

FYI the retaining pin on the pressure dial fell out when I was adjusting it. Took a bit to put it back .

[@ForwardMomentum]

Good catch!

[@BrianJr73]

how did you get it back in

[@bartw4031]

@@BrianJr73 It was an exercise in patience due to my slippery fingers . I used a small screwdriver to hold the dial in its place while I replaced the pin. I was worried for a while that the dial coming out screwed something up, but it's been a year and all seems to be fine.

I personally went with Moog. A lot of people say 555’s are the best. Lots of choices but it’s a part I won’t skimp on.

[@HussarPlays]

If the 3rd Setting is better over all for transmission, what are the benefits of having it set anywhere else? Been considering a GS, and been getting a steady diet of your videos today. I appreciate the content

[@ForwardMomentum]

The other settings decreased line pressure, making the shifts more comfy; kind of like a rich old man heading to the golf course wanted back in the late 90’s apparently. 🤣

Facing the engine from in front of the car, the alternator is at the bottom left. You have to lift the car, and get under it to remove the alternator. You may have to remove the power steering pulley to access the top screw to remove the alternator. Once you know how to do it, it's a 10 minute job. To get the PS pulley off, keep the serpentine belt on, and use it to keep the pulley from turning as you un-torque the nut.
