What Trans is this?

Is it usable with a rb25 neo?

Well.... maybe. What TCU is there? Keep in mind that a NEO ECU either expects to also be the TCU (when it's out of a GT-T) or it expects to talk to a separate TCU. There are specific bits of information that go backwards and forwards between these boxes, and it is almost certain that a Z32 TCU won't speak the right dialect.

If you were using an aftermarket ECU with the Neo, it would probably be a lot easier. And in fact, these days people like Haltech are rolling transmission control into their ECU's capabilities because of just these problems.

It would also be possible to go a standalone aftermarket TCU, although that might be difficult to integrate properly with a factory Neo ECU, for the same reasons again.

If it is in an R31, and behind an RB, then someone has probably put it together, because the VG bellhousing is not the same as the RB bellhousing, even if there are usually similar gearboxen hanging off the back of them.

Google search of 51x00 shows up many parts that refer to Z32, but that may or may not mean anything. The number also shows up some Maxima parts (which were also VG, but FWD) and so it is possible that it pertains to a whole slew of Nissan trannies.

Google of model number shows 300zx

Post up what the entire tag says. Is JATCO mentioned. If its a RE4RO3A, I have one in a R33, bolted to a RB 30/25 with neo head and cold side. It physically fits with modified converter, tailshaft and rear mount. The RE4R01A bellhousing for Skyline bolts straight on.  Never got the box to play nice with the Nistune R32 ecu and matching TCU  so went manual valve body to make it work. Are you confusing big shift kit with manual valve body.

    • Does this count as a time trial as well? I got all gold in the master super licence (1 lap time trial) and received a McLaren MP4/4 for my trouble.  If anyone else has done this, did you ride the wall right around the first long right hander at Lake Louise snow track to get gold? I couldn't do it any other way... best I could do without riding the was was within 2 tenths of the gold time.
    • I definitely get the low power, sporty car to drive to smash gears but not be doing eleventy million miles an hour! It makes all the normal drives fun!   Rev match tune sounds like the funs! I didn't know the NC had a DBW throttle!   As for me, still have the Skyline, it still has the Barra in it. It's been pushed to the side of the workshop at the moment. Pretty much waiting on me finishing the wiring, and dropping new fuel lines in. Got myself an ACDC Tig end of last year so been teaching myself TIG welding to build a few things for the Skyline. The missus wrote off her GTB liberty at the end of last year, and got it back on salvage rights stupid cheap. It's also still registered, so will mean easier for me to take to the track already done most of the panel damage, just playing "clear the workshop" to make space to pull the motor and box out, fix some oil leaks, replace the clutch, and replace a few minor broken things.  Also got a Lathe at the start of the year, which is adding to the annoyance of no space, which is another reason I'm trying to build things to get more space, to get the Lathe back in a final home for it. It's a BIG lathe, can turn a 355mm diameter, and 1metre between centres... Got it at a steal! So between it and the TIG and old MIG welder, I'll be fabbing some fun little shit up But we've had a lot of shit stuff happening at home, so it's slow going getting things done. But one step at a time!
    • I love Catalunya.  Got a 1:54.632. The AMG is a hoot.
    • I hadn't got that far, my main worry was the connection to the actual calipers themselves. I'm just using new (ish) stock brake lines in the stock setup. I've just had a stud welded to the knuckle that is a little lower than the original stud (so my knuckles have two studs each side) to not have it be stretched so far in previous BBK setups, so the "block" (in the second picture) mounts a little lower for me and I hope I don't need to change anything. I may have even changed the connection to the calipers in the past and have since forgotten I did that. I may not have. Guess how I'm gonna find out. Source: hopium
    • It's more so I'm using the 1x piece line from HEL that goes from the body to the caliper. There's no middle block/mount like the HFM ones or the GKtech ones. There are certain angles/suspension compression where the line actually slightly contacts the ARB. Below of how mine sit (not my photo): How I want it:
