Transgo 340HD2 Reprogramming Kit Install - A343F A340E ('85-'08) 

Thanks for the tip Mike.

Hows it working out so far? About to order one for my 2000 XJ. Any advise?

​@@tmmyjayMy XJ still has the front axle out. My trans is back together, but I've yet to fire it up and drive it. 2024 goals! 😂

Great to hear the Sean and Chris's video helped you out. Good luck with the job and you're very welcome Reinhard.

HAVE TO DO IT STEP BY STEP. GOOD LUCK

You're welcome, and good luck with the job

Getter Dun!

Yes, this installation video was completed on a 2000 Toyota 4Runner 4x4. - Sean

Thanks for stopping by the comments and come back in j case you have any questions along the way. We appreciate your comments as we know you have been a subscriber since day 1!

Have to do the honey do list happy wife happy life I can vouch for it. Great job guys & no parts left over great

Thanks Jared. Good luck with the job.

@@TimmyTheToolman Thank you !

We're not sure. We just installed the parts that came with the kit.

It can be suitable for a daily driver. But keep in mind this kit is meant for race applications and shifting will be more harsh. I like how smooth my 4Runners shift personally, expect my supercharged one.. I would def do it on that one. - Sean

@@TimmyTheToolman Thanks for the response Sean. This is what I was hoping to hear. Claudio

FIPG is far superior to paper, metal or cork gaskets. The reason it's superior is it can flow into imperfections in the metal that the others can't. It can make the difference between no leak and a leak.

You are welcome!

Good to know an o-ring helps with that connection.

Look in the video description of this video for the parts list for the Valve Cover Gasket job. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N5fAXAuGozI.html

He’s hiding. Check out our other most recent videos.

Yes shifting into reverse in general not even just from drive feels very jerky. The symptom that lead me to the solenoid was when I don’t fully stop at a stop sign (rolling stop) and then I press the gas I get a weird shift/loss of power between 1-2 shift. If I fully stop it doesn’t happen at all, new solenoid actually didn’t end up fixing this problem after driving it for a while. That solenoid definitely wasn’t functioning though 😅..

Solenoids handle shifting… do you have bigger tires on your truck? And/or mud terrains? - Sean

You're welcome!

It's normal for them to shift rough when cold and smoother when warm. Transmissions shift better when the fluid is up to operating temp. As the temp goes up, the fluid thins out and allows for smoother shift.

I don't think this Transgo kit will change how much throttle input it takes to get the transmission to kick down. If you have an earlier yeah 1st Gen Tacoma with the throttle body that has 3 cables going to it (throttle, cruise control and kick down), you can take slack out of the cable to make the kickdown more responsive. You simply loosen the 14mm nuts for the transmission kickdown, make the adjustment to take some but not all of the slack out of the cable and lock it back into the bracket with the 14mm nuts. You can easily figure out which cable is the trans kickdown by seeing where the cables run too. The trans kickdown runs back under the rig to the transmission. Hope this helps.

No clue. I think you might have to ask the manufacturers of both kits to find out.

The paperwork/documentation comes with this kit in the box but they also have a digital copy on their website. res.cloudinary.com/transgo/wbiss/rk/340HD2.pdf - Sean

Unless you’re making 6-800 whp, you’re not gonna break your A340E with just a TRD SC, and 😊this isn’t going to beef anything up, it’s just a shift kit!

Are you on drugs? An A340 isn’t taking anywhere close to that power in stock form.

Maybe contact Transgo and ask if they can explain its benefit to you better.

@@TimmyTheToolman considering installing one of these kits, could you explain why you decided not to add the 1st hold mod? I believe the low hold mod allows for engine braking in 1st gear/LL within a limit dictated by the impeller in the TC. I say within limits because the TC still won’t lock up in 1st. Would be a great addition for wheeling to avoid the runaway feel on the downhill?

I would check with your local Toyota dealer.

Nothing specific, we just soaked up the trans fluid with a bunch of rags. That type of cement inside the garage doesn’t absorb the fluid. But some simple green works well and auto parts stores have degreasers for floor cleaning as well.

Use Super Clean, works better than the Simple Green

I used a a squeegee to try to get as much fluid into a drain pan then soaked up the rest. Laundry detergent and a push broom to scrub works wonders for getting oil stains out of concrete though

Your question is above our pay grade. We have zero experience with the Prado models. Your question would be better answered on a Toyota forum or maybe a dealership could help you. You just need to find out what model Aisin transmission you have.

Yes, we think the Transgo kit is a good way to go. If you're already going to have the transmission torn apart, it will give you firmer shifts and reduce clutch plate wear. I'm curious, who's going to rebuild it?

@@TimmyTheToolman I am actually with aid of a friend. I bought a rebuild kit from OPT which comes with a manual and there is a fantastic 3 part video series of a college instructor rebuilding one (Michael Fleming). So between those two I should be ok. I plan to photo each step and take my time. I will probably buy a torq converter and will likely replace one set or more of the planetary gears as I read they are prone to fail in the early year Tundras. There’s also another guy on youtube, an Australian guy who does a lot of transmission videos including how to properly test and clean solenoids. In short, I couldn’t afford a 4k rebuild so going DIY while also installing better components is my best option and saves $2000.

@@oldowl4290 I think I watched some of that series from the college instructor. The overdrive planetary gears for the 2001 and 2002 4runners are known to fail. Good luck with the rebuild. We are hoping to do a video on rebuilding one fairly soon.

@@TimmyTheToolman FYI, I found out that the A340 issue is in fact not the gears but the torrington needle bearing between the OD planetary and ring gear and this is not just an 00-02 issue. Once that fails it in turn destroys the planetary gear set. It's a lubrication and overheating issue, such as with towing in overdrive where the torq converter is unlocking and continually downshifting, searching for lower gears. My friend is a master yota guy and after very thorough parts searching we found ZERO evidence of any actual part change numbers, supercession, upgrades, etc, for the 03+ years all the way up until the next get A750 series at which point some things do change. So the only remedy really is to put in an 06 trans into any year prior. I did however find just one trans company in Alberta Ca. that was previously rebuilding the OD gearsets with a larger torrington which also requires machining of the planetary race (pocket) where the bearing sits, in essence replacing the 1.5" OD bearing with a 2.0" OD bearing that has slightly thicker needles. The problem however is they stopped making these a few years ago due to lack of parts to rebuild (because so many were shredded).. so they are no longer making this modded set! In a nutshell, this means anyone who has an A340 is driving a time bomb as far as I'm concerned. The only #1 thing people can do immediately, is replace that bearing.. especially every 100k miles for preventative measure and if possible find a way to install a larger one, machine the race, etc. I actually called countless places nationwide trying to get a new/used gearset and only 1 place had a set..only one. I was extremely lucky to get it. If you want a new set from Toyota just the planetary alone is $1000 and includes no mods. I got my used set (planetary, ring, sun, etc) for $200. I'm also installing a slightly larger transmission cooler, derale 13011 thermostat and a MaxTow temperature gauge.

@@oldowl4290 Wow, thanks for sharing all that information. I guess I'll just hope my trans doesn't implode.

De Nada.

You'd have to find a shop that specializes in modifying vehicles. This is a job that normal automotive shops or dealerships wouldn't want to take on.

Quote coming your way shortly 😎

To speak for Chris, it was definitely a challenge to find the right ones. If you have a 2000 limited with a push button 4wd shifter like Chris has, then the solenoids we link in the video description should be the right ones for that platform. He basically had to remove them first and then he compared them with pictures that PARTSOUQ had to get the right style with the right mounting brackets attached.

@@TimmyTheToolman Thanks! I called the local dealership and provided the VIN number of my 97 4runner but they could not tell which solenoid to order. When I plan on doing the Transgo kit, I will then pull the solenoid.

Open the video description by clicking on "More" and the video description will expand out. You'll then see a link to the kit.

I don't know if Chris owns a small impact driver. With small fasteners like that, I also like to feel what's going on with a standard ratchet. Less chance of snapping off a fastener. I do like my Milwaukee cordless ratchets and I probably would have used one of them to speed up the time to remove all the bolts. I would break free the bolt using the cordless ratchet like a standard ratchet and then use the electric assist to spin it out much faster. I definitely agree with Chris not using any electrical assist to install the bolts due to the higher chance of cross-threading or snapping off a bolt.

@@TimmyTheToolman oh yeah for putting it together 100% but taking all those well lubed bolts OFF? I’d use battery power every day.

@@FK-we1dp what can we say? Chris is a glutton for punishment, even from the wifey! 🤣

@@TimmyTheToolman lol you guys rock

No, it would work for the 1st Gen Tacoma.

@@TimmyTheToolmanthank you for answer . What about the smaller shift kit ?

@@Paddockguys I don't understand your question. What smaller shift kit?

@@TimmyTheToolmanSK 340

@Gwero11 So, are you asking if we've installed the smaller kit? Can you please use more words to describe what you're asking? If you're asking if this other kit will work for your 3rd Gen 4runner, I don't know. I'll leave it up to you to do that research.

We don't have one but I have a suggestion of where you might be able to get one. Josh Young runs a business in Washington called PNW 4runner Connection. He parts out 3rd and 4th Gen 4runners. You can contact him via his Facebook Page. facebook.com/PNW4RunnerConnection/ Tell him Timmy the Toolman referred you.

Chris has reported that it definitely made the shifts a bit more ‘crisp’? Not sure if that’s the right word to describe it, but ultimately it made the shifts more noticeable. - Sean

@@TimmyTheToolman I recently bought it and want to use the truck setting and not the hot rod. Any suggestions?

The chances of somebody answering your question on our channel is slim to none. You're better off asking your question on a Jeep forum or Jeep Facebook group.

We agree it was a bit on the messy side. That is a great analogy. Working on vehicles is a lot like medical surgery.

@@TimmyTheToolman Yes, it was definitely an interesting video, like performing a heart surgery! 😊👌🏽

Well, at least the sun gear will be happy because it's getting blown.
