4th gear synchro's are cactus, and there's something majorly wrong with the selector fork and/or rod for 3rd/4th.

fix'n or replacin' - I don't really mind, as long as I have a properly working 'box at the end of it! :)

See last post for current situation . . . . all good so far !

Saw one in the FS section the other day for $1550, claims it came out of a low km car...

That's Stoney up in Sydney?

I've phoned around a few places, sounds like $500->$1500 to rebuild, depending on what's busted-up in there.

Oh - and Nismoid: 4th's synchros have been going steadily downhill for ages, I think that's lead directly to the selector problem. The actual Cogs feel Primo ! ! :pirate:

yeah i busted my 3rd/4th selector fork in half.... just picked up a second hand box and scored a good one!

its a bit of a gamble.... but if you dont want that, just rebuild it...

just for parts from nissan alone, all bearings, all syncros and a 3rd/4th gear selector fork was quoted at ~$1400 trade

so depends what parts you need, and whats wrong with the box

hey mate, a good place to get a rebuild is 360 gearboxes, they are in kilsyth.

The guy who owns it name is bryan.

So, 'box is dropped, Here's some of what came out with the (pretty, shiny) oil:

Note the Lil' clip here, left of the plug - that dropped out with the oil. Who KNOWS what else lies at the bottom of the Box?!

Saw plenty of Synchro-shards, and OOOHH BOY is there some filings in that-thaaar oil !

Competition Gearboxs in Croydon. (03) 97233380 or 0408650060. They specialize in Jap gearbox's.

Factory 6/35 Lusher Rd, Croydon.

My mate Kris (O-Y-K-B on here) got his rebuilt through them an his was probably in worse condition than yours. Good quality work done at a reasonable price (cheaper than a secondhand box) . Price all depends on the ammount of damage i guess.

best of luck

Yeah, thanks abcent - A mate in the trade is seeing in the morning if he can get a changeover from Japanese Gearbox Wholesalers in Rowville, if not I'll probably flip a coin between 360 and Competition - they both sound pretty good, and charge similar rates, and they're practically a stone's throw from each other !

I did the same in my 33 twice :stupid:

I had the second box rebuilt with a new 3rd/4th fork bearings and syncros. Cost about $1500. It seems fine to drive I just have to go easy with the gear changes.

Goodluck with it anyway.

Talked to Simon @Competition gearboxes today, He said the input shaft is rooted, as well as the 3rd/4th selector sleeve. 3rd/4th selector fork is SHATTERED, with half lying on the bottom of the gearbox case - 4th syncro is more or less gorne!

Shall see how We go with the parts/rebuild - fingers crossed !

I had Simon rebuild my gearbox about 3years ago.

I needed a new reverse gear (wtf did the previous owner do to it??) & the 4th gear synco was crunching when changing above 4000rpm.

He fixed the reverse and is all good 3 years on....but the 4 gear syncro problem reappeared after close to 2 years had passed....and i do NOT flat shift :)

thinking about another rebuild now....:)

    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
