Hi!

I´ve got some synchro scrape/noise when switching to fourth and fifth gear.

I´ve been told that this is a common problem with the R33 manual gearbox.

Who in Perth could rebuild an R33 gearbox and has someone got an idea what it would cost?

yeah but when your synchros are gone its a pain in the ass. cant shift into certain gears at higher rpm's. I mean its still very driveable but as they said you can replace the g/box with one from a wreckers but who knows if that doesn't have the same problems. Replacing synchro's will set you back about $1000 + labour.

Try some Redline oil first

I have the same problem, crunches at high RPM going to 4th. might try some Redline oil first, but am considering rebuilding the box if or when it fails.

If i was to get a box from the wreckers is there a fair chance it could be also hammered n soon will scrap?

If i was to rebuild is there any way to make the syncro's and gears stronger with aftermarket parts? or a is there other boxes you can put in that are better / stronger?

well if you want your gearbox syncros replaced i had a few replaced and my gearbox fixed up (bearing was fked inside it) at perfect transmissions in bibra lake, awesome guy knows his transmissions! him and a friend were the only ones to actually guess RIGHT what was wrong with my car..all other mechanics wouldve cost me 2k+ (due to them going to replace the clutch first...) only cost me 1k total for new syncros and some bearings fixed oh and new thrust bearing just for the sake of it (even though i had a new clutch in anyway) :P

basically took the car to the shop to get a crunching fixed (was the bearing) and he fixed it (he does cash jobs to)

uhm wasn't a recon but he atleast told me the condition of the gearbox which is it's still good (strong gearboxes :()

but yeah...1k cash for labour + syncros (2nd and 3rd i had replaced i think it was...) + bearing + thrust bearing

my advice is though if you DO see him... ask when he actually NEEDS the car.. cause he had mine for a couple of weeks lol before he got to work on it (he can be very busy) like 10 cars somehow fit into his shop... i dunno how haha

good place though ;) great guy

Sounds like it´s worth to pay them a visit. Should be alot cheaper if I just get the gearbox of and hand that one in... should save some money on labour...

Also what I was thinking.

Anyone know if it's true that 34gtt boxes have dual synchros?

i've heard of that before... i can possibly call up the dude who took apart my gearbox lol but yeh... i mean i had the option as well as goin well do i fix my gearbox.. or replace it... it came to the 'if i replace it...it could be as rooted as my current one :S'

so i fixed it :(

I´ve come to the same conclusion... What if.... That´ll suck!

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
