AWD 6MT TT build

takemorepills · 11-09-2021, 10:54 PM

Sooo....
This would be a bit easier if one were to begin with an actual G37x AWD?

Also, did you consider the early-2000's Nissan Pathfinder that had both a MT, AWD and VQ power as a parts donor? I've always wondered if there's any usable MT swap parts from that platform....

Nah it's a lot harder to turn a g37x into a Z than it is to swap awd lol the Pathfinder, Xterra, frontier box has the transfer case drop on the wrong side, has the wrong bellhousing bolt pattern, and generally doesn't work. If I were to do this all over again I'd say get an R34 box or an r33 5 speed and a bellhousing adapter.

I have access to one of those but the 5 speed will **** the bed unless you get the quaife gear set

There is also no room for the reverse gear speed sensor so that would need to be relocated as well and a new trigger wheel made to emulate the pulses of the gear teeth.

I hadnt considered the calibration procedure, perhaps it could be skipped though. We planned to use the DCT controller to emulate the X/Y axis voltages for rev match, but so far have not bothered (revmatch isnt going to be able to hit target RPM before a preselected DCT shift, though it would probably be helpful when a downshift was not preselected), so I cant say if it would actually work or not.

What is the relationship of the reverse gear speed sensor? I dont know if I even realized there was one. I thought S-Mode was comparing engine speed from the crank trigger, to input shaft speed on the trans.

There is a speed sensor that reads off one of the reverse gears teeth and is used by S-mode. Don't ask me how it's used but if it's not there I guarantee you rev match will be dead

Well at least it's stronger than a Subaru 5spd lol, and the R34 box is a tough call because they can go $8k now.

You could probably sell a whole lot of your transfer case adaptation kits for this transmission.

I saw something similar not long ago when a company produced a kit to install the Getrag DCT I used into the RB Skylines. They had to take this RWD only trans and make it accept the RB transfer cases. When they showed it off, it seemed there was a greater number of people wanting just their transfer case kit, for various non-RB powered cars.

With how popular the "CD009" style transmission is, I bet you can sell your transfer case adaptation kit 10:1 more to people who will use it in the most random ****.

I am guessing the sensor on the reverse gear is the "input shaft" speed sensor. They just have it down the line for packaging or something. I couldnt find any other speed sensors on that trans.

That's why I really wanted to make a kit but it's whole lotta Bs.it requires a modified tail housing from another Nissan that has to be pulled from a core trans because Nissan won't sell it separately, as well as the plate, the control shaft, the seal plate, you have to modify the center plate, a bunch of parts for the neutral return springs, the shifter is reversed left to right in the linkage, the neutral switch piece on the control shaft is modified, and more. It would probably take me the better part of a year full time to actually make everything at a quality I would feel comfortable selling as a kit and you would basically need a shop comfortable with rebuilding the trans to do it. Basically the cost to do the conversion would be a toss up with just buying an r33/R34 trans and adapter kit.

The better option would be custom selector shaft and a billet tail housing to use the skyline transfer case and shifter on the cd009 that would fix most of the problems but that tailing housing would be ~$2k machined and the transfer case is at least another $1500 plus an aftermarket controller and the now almost unobtainable hydraulic system for the transfer case.

With a billet tail housing you could retain rev match by adding the provisions for the sensors, since the shifter is mounted in the tcase you would have the room you would just need an extended selector shaft to mate with the shifter.

Didn't say a thing about turning a G into a Z. Just curious because I have an AWD G, and it seemed like a lot of work to deal with some of the unibody aspects of AWD into a Z.

Many moons ago I had a 2002 QX4 with the VQ35 and Attessa AWD system. Didn't realize the transfer orientation was different.

lol..I think?

Yep wrong side and yeah you would just need to swap in a manual trans harness, get your bcm flashed, change the pilot bushing, get the manual shifter trim, redo the cross member, get a clutch and flywheel, change out your pedal assembly for a manual one, drill holes in your firewall and mount the master cylinder, fabricate a clutch line, and adapt in a manual transmission. It's enough work that you aren't any further ahead. It only takes 3 days to swap the mounts weld them in and widen the tunnel. The hard part is the transmission. I thought you were giving me snarky attitude of "why don't you just buy an AWD"

The other problem with the "truck" transmissions is the ratios are literal garbage and your' 2002 was a de so the trans still has the wrong bellhousing bolt pattern(the de, the vq40, and the hr/vhr all have different bolt patterns)

Also you could probably start with getting an FX35 front diff and manual 370 rear diff(non2015 up nismo) and enjoy the 3.69 ratio first

When you're done with this and get bored....you can then switch it to a Safari build ha, already got the 4wd!

1slow370 · 11-11-2021, 06:06 PM

Nah I'm not going safari, they tend to get destroyed by all the bottoming out and frame abuse not to mention all the scratches and corrosion and driving like **** when you try to daily them.

I've purchased this car twice now and I plan on keeping it in good shape as long as I can lol

phunk · 11-11-2021, 06:38 PM

If that is a clutch pack transfer case like a GTR has, it wouldnt last a half hour off-road anyway. Youd want to use a center differential from the trucks.
