Hey my gearbox is crunching every now and then, when shifting up to 3rd or 4th (sometimes when driving hard; other times when crusing) ... i am thinkin maybe my syncros are going?

I plan on changing the gearbox oil this weekend and seeing how that goes.. however if this doesnt cure my problem, what am I looking at for a repair cost??

sncryo's + labour?

rebuild of the gearbox?

new gearbox?

just so i can see what the best option i can take is..

tnhx

Do yourself a cheap quick and easy favour and buy some "Redline Shockproof Lightweight Gear Oil". Put that in, give it a solid 500-700km of driving and then count the dolars you saved on that rebuild.

www.uas.com.au sell/deliver the oil. Call john and mention this to him and I doubt you'll get off the phone in under 10mins :cheers:

I never used to have any crunches but since my car got a high idle (upto1900rpm) i find it hard to change from first to second without sum difficulty and a bit of a clunking feeling thru the gear shift. It only happens up gears really and mostly between 1st and 2nd..Sumtimes 2nd to 3rd. Would the high idle cause this in anyway? If not would the shockproof fix it?

Thanks,

Deren

well i picked up some redline shockprrof on friday... got under the car today and tried to undo the top plug, with no luck... i huff n i puffed to no avail.

There seems to be some kind of silicone compound sealing the top bolt in. Can anyone let me know how to loosen this up? or do i have to hire a body builder for 5 minutes?

If worst comes to worst how much will a workshop charge me to hoist it up and do the change for me (noting that i will supply them the parts)

Everyone at UAS said the shockproof will fix it.

Mine still crunches in high revs post shockproof, what really helped however was them also bolting in my clutch slave in properly :cheers:

If your syncros are buggered I doubt oil will fix it, if you haven't changed oils for a while then you have a good chance any oil change will help it :)

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
