stationary.. MY gearbox is SMOOTH. when driving.. i gotta crunch it in.. anyone know what it is?

I think it myt be the transmission fluid..

any recommendations? for a very smooth oil gear box change

Hi!...

It's a good question...(and I will do my best to give you the least technical explanation I can, which should be easy!..LOL!)

..and I reckon is one that is commonly asked, or at least considered.

But I can only be very general in my response, as each driver and gearbox performs/wears differently.

In my own personal experience..... Nissan boxes are noisy!...Simple!...

Don't get me wrong..I love them,..they are strong and take a lot of abuse...(we all know that!)

Synchros do wear, it seems that 2nd and 3rd are the first to 'slow down'...

Thrust bearings are notorious noise makers....on our cars...(I just got a new Rissan one installed, with only a slight decrease in noise).

Sometimes the use of specialised additives..in your gbox can help, sometimes they don't, sometimes they can hurt your box.

Where is your 'crunch', ....when does it occur.....does it occur when the box is cold......in hot/cold weather....does it occur during 'spirited' driving?....sometimes oil viscosity/quality can make all the difference.

It may be that you need to look into (major) servicing of the box.....it could be a few dollars?..could save you a few too!

I have always let my cars warm up....engine and box, prior to stabbing...could it make a difference to you?...dunno.

Will an additive (<>60-120 buh) help you??.......dunno...could be a could place to start, for cheap.

Synchro/box service??......yep, that should do it!......but........$$

I will let the experts give you the tech run down.....but just letting you know that many of us experience "the crunch", in one form or another........they are a noisy/crunchy box nowadays!!

Cheers.

mm.. i gotta crunch it into 2nd gear and sometimes 3rd.. and 4th.. when stationary, my gearbox is smooth.. when driving its rough..

anyone in melbourne wanna try it out? and compare to their cars..?

Your synchronising gears are worn.......or your clutch is stuffffffffffed!

I think a few memebers here have answered that already for you.

Where abouts in Melb are you?.....

I have the same problem, second and third crunch bad, But only when cold, after driving to work leaving it all day and driving home its fine, all my gears are smooth. I was hoping it would only be the gearbox oil or something cheap haha.

seems that in YOUR case....an additive or oil flush and application of a quality oil MAY help you out.

Check it and come back to us.

i'm in the city.. i can come down to you if u like :banana: my clutch is a heavy duty clutch APPRANTLY worth 2750.. just put in about 2000km'z ago..

$$$$$$$$!!!!.........is it just a 'heavy duty' clutch...or one of those craaaaazzzeeee puck/button clutches...(can't stand those things on a road car).

Did you put it in YOself?...Is there a chance of going back to the person who charged you (that did the work)?????

A clutch and a synchro set are very different things.....

A heavy duty Clutch could be making the problem worse...I just don't know!

We'll wait to see what the rest of the guys suggest.......just hang on.

      R34 Skyline climate control unit transistor

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
