Super drivable built auto box setup!

Every now and then someone posts saying "I'd like to upgrade my gearbox as I have an automatic Nissan Skyline". A lot of the time people say GO MANUAL and every now and then someone gets a shift kit. But every now and then someone resists the repeated insistence of people to just GO MANUAL and jumps off the deep end. I am that guy.
Now you can be that guy, at a massive, massive discount. It could almost be argued it was a decent idea.
This gearbox is a RE401B from the R34 GTT, which has been overhauled from scratch by DTM Automatics in Geelong after being dis-satisfied with the MV Kit that was previously in the car. Which died. They have made a completely custom valve body which supposedly flows amazingly, with upgraded bands and have a billet shift servo. Fancy words. This has not died, for many many years.
 
In addition to this there is a custom flex plate that has been heavily reinforced over the standard one (it's a modified version of the yellaterra flex plate for the RB30, to make sure you don't snap the stock one with your soon to be massive torque. Note: The stock one is NOT good enough for 300kw!
It has a custom Torque Converter from TCE which are one of the best in the business, according to a fair bit of googling. By "custom" I mean I went in there with the blueprints for the engine, and the dyno sheet from the most recent tune and they took that and built a stall converter purely for that purpose. It's enough to generate 5-10psi at stall near instantly which is WAY MORE than you will need to obliterate any road tyre off the line. The downside of that is such a converter creates heat, but don't worry about that, because It has twin coolers, complete with a nice digital guage to tell you the transmission temp. If you're worrying, I got it to 100C during a full session at Sandown without any kind of cooldown lap. It usually drives around town at about the 50-60 mark. This is actually under what Castrol kind of recommend for performance driving, and usually about 80C.
In otherwords, the coolers are cool.
 
But the best part about it is the PCS TCM-2000 which is a standalone ECU which will cost you about $1000 USD to buy on its own, let alone wiring it in, let alone tuning it. What this allows is for you to tune your shift maps, it allows you two different maps which is already tuned in this car, for a more pleasant "D" mode to your super hardcore triptronic/manual mode.
The best part about it all though, is that unlike other aggressive shift kits, which in order to shift hard up top, have to shift harder down low, this behaviour is reversed with the ECU. Allowing nice comfortable shifts down low, and HARD shifts when you are giving it the beans. All controllable by the TCM, and it absolutely will not shift in manual mode until you tell it, under any circumstances. If you want, you can tune the kick down/shift up parameters of the "auto" mode as well.
 
It has held 300-420KW for years. Trent @ Chequered Tuning would and has vouched for its unrelenting reliability. If it died tomorrow and I wanted I'd take it back to DTM and get them to make another one. See here ->
 
You could too, if you wanted, but if you did you'd probably be paying north of $10,000+ fitting and wiring and tuning it all.
You should buy this instead.
 
Because noone uses an auto, before this comes out of the car, I'll make a short video showing it in "action" to give an idea of how livable it is or isn't at some point. If you are local to Vic, I'm happy to take you for a spin in the car so you can drive it for yourself to see if it is something you want. I'd much rather do this for any interested buyers so let me know, all the cool kids are on paddle shifters nowadays, didn't you know?

I want $3500, which is actually about the cost of the ECU, the Torque Converter and the Flex plate. I am 100% certain you will send lowballs, dear reader.

okay, so this is now officially out of my car and onto the floor of my garage, ready to ship to you, or something along those lines.

In short, I miss the torque this auto supplied. Really had no idea it had such a large effect. But there you go. If you REALLY want to get going in a hurry, well, I can see why people build autos.

Anyhow, here is two videos of me driving around town very briefly.

 

As you can see, it really requires next to no effort and very little revs to get going around town, and isn't a slippy nightmare that cannot be driven because hurrr durr torque converter.

At high RPM it shifts much more severely and much quicker. As evidenced by me spinning off at Winton because I changed from 2nd to 3rd at high RPM and forgot about this.

 

 

Whoops. There's another video or two of me track "Driving" like a n00b if really concerned as to how well it shifts or doesn't under abuse. Mind you, this is at super low boost (12psi) which I guesttimate at about 250kw. Useful if you're like "wow that thing really sucks power" or something.


Here's photos of all of it out of the car.

NOTE: the photo above, is what will happen to your own flex plate if you run any serious power through it. So if you're randomly reading this, have an auto, and don't want to buy this, at least consider getting a custom flex plate made!!

    • I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.
    • Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too. 
    • Any update on this one? did you manage to get it fixed?    i'm having the same issue with my r34 and i believe its to do with the smart entry (keyless) control module but cant be sure without forking out to get a replacement  
    • So this being my first contribution to the SAU forums, I'd like to present and show how I had to solve probably one of the most annoying fixes on any car I've owned: replacing a speedometer (or "speedo") sensor on my newly acquired Series 1 Stagea 260RS Autech Version. I'm simply documenting how I went about to fix this issue, and as I understand it is relatively rare to happen to this generation of cars, it is a gigantic PITA so I hope this helps serve as reference to anyone else who may encounter this issue. NOTE: Although I say this is meant for the 260RS, because the gearbox/drivetrain is shared with the R33 GTR with the 5-speed manual, the application should be exactly the same. Background So after driving my new-to-me Stagea for about 1500km, one night while driving home the speedometer and odometer suddenly stopped working. No clunking noise, no indication something was broken, the speedometer would just stop reading anything and the odometer stopped going up. This is a huge worry for me, because my car is relatively low mileage (only 45k km when purchased) so although I plan to own the car for a long time, a mismatched odometer reading would be hugely detrimental to resale should the day come to sell the car. Thankfully this only occurred a mile or two from home so it wasn't extremely significant. Also, the OCD part of me would be extremely irked if the numbers that showed on my dash doesn't match the actual ageing of the car. Diagnosing I had been in communication with the well renown GTR shop in the USA, U.P.garage up near University Point in Washington state. After some back and forth they said it could be one of two things: 1) The speedometer sensor that goes into the transfer case is broken 2) The actual cluster has a component that went kaput. They said this is common in older Nissan gauge clusters and that would indicate a rebuild is necessary. As I tried to figure out if it was problem #1, I resolved problem #2 by sending my cluster over to Relentless Motorsports in Dallas, TX, whom is local to me and does cluster and ECU rebuilds. He is a one man operation who meticulously replaces every chip, resistor, capacitor, and electronic component on the PCB's on a wide variety of classic and modern cars. His specialty is Lexus and Toyota, but he came highly recommended by Erik of U.P.garage since he does the rebuilds for them on GTR clusters.  For those that don't know, on R32 and R33 GTR gearboxes, the speedometer sensor is mounted in the transfer case and is purely an analog mini "generator" (opposite of an alternator essentially). Based on the speed the sensor spins it generates an AC sine wave voltage up to 5V, and sends that via two wires up to the cluster which then interprets it via the speedometer dial. The signal does NOT go to the ECU first, the wiring goes to the cluster first then the ECU after (or so I'm told).  Problems/Roadblocks I first removed the part from the car on the underside of the transfer case (drain your transfer case fluid/ATF first, guess who found out that the hard way?), and noted the transfer case fluid was EXTREMELY black, most likely never changed on my car. When attempting to turn the gears it felt extremely gritty, as if something was binding the shaft from rotating properly. I got absolutely no voltage reading out of the sensor no matter how fast I turned the shaft. After having to reflow the solder on my AFM sensors based on another SAU guide here, I attempted to disassemble the silicone seal on the back of the sensor to see what happened inside the sensor; turns out, it basically disintegrated itself. Wonderful. Not only had the electrical components destroyed themselves, the magnetic portion on what I thought was on the shaft also chipped and was broken. Solution So solution: find a spare part right? Wrong. Nissan has long discontinued the proper sensor part number 32702-21U19, and it is no longer obtainable either through Nissan NSA or Nissan Japan. I was SOL without proper speed or mileage readings unless I figured out a way to replace this sensor. After tons of Googling and searching on SAU, I found that there IS however a sensor that looks almost exactly like the R33/260RS one: a sensor meant for the R33/R34 GTT and GTS-T with the 5 speed manual. The part number was 25010-21U00, and the body, plug, and shaft all looked exactly the same. The gear was different at the end, but knowing the sensor's gear is held on with a circlip, I figured I could just order the part and swap the gears. Cue me ordering a new part from JustJap down in Kirrawee, NSW, then waiting almost 3 weeks for shipping and customs clearing. The part finally arrives and what did I find? The freaking shaft lengths don't match. $&%* I discussed with Erik how to proceed, and figuring that I basically destroyed the sensor trying to get the shaft out of the damaged sensor from my car. we deemed it too dangerous to try and attempt to swap shafts to the correct length. I had to find a local CNC machinist to help me cut and notch down the shaft. After tons of frantic calling on a Friday afternoon, I managed to get hold of someone and he said he'd be able to do it over half a week. I sent him photos and had him take measurements to match not only the correct length and notch fitment, but also a groove to machine out to hold the retentive circlip. And the end result? *chef's kiss* Perfect. Since I didn't have pliers with me when I picked up the items, I tested the old gear and circlip on. Perfect fit. After that it was simply swapping out the plug bracket to the new sensor, mount it on the transfer case, refill with ATF/Nissan Matic Fluid D, then test out function. Thankfully with the rebuilt cluster and the new sensor, both the speedometer and odometer and now working properly!   And there you have it. About 5-6 weeks of headaches wrapped up in a 15 minute photo essay. As I was told it is rare for sensors of this generation to die so dramatically, but you never know what could go wrong with a 25+ year old car. I HOPE that no one else has to go through this problem like I did, so with my take on a solution I hope it helps others who may encounter this issue in the future. For the TL;DR: 1) Sensor breaks. 2) Find a replacement GTT/GTS-T sensor. 3) Find a CNC machinist to have you cut it down to proper specs. 4) Reinstall then pray to the JDM gods.   Hope this guide/story helps anyone else encountering this problem!
