R32 Gtr: Very Difficult To Select Gears

Ello.

I have a bit of a problem with me clutch/gearbox - 1st is very difficult to select, and 2nd also gives me trouble (and even 3rd slightly shows some resistance) but especially the reverse gear..

Now I'm quite sure it's not the gearbox (?) as I initially thought, but more the clutch - the reason I say this is that even though the clutch is fully pressed down, when I select reverse (eventually after quite a struggle), it feels as if the gear is now engaged as the car starts to move slowly (on a flat plain).

Also, my clutch has recently become (more) heavy... so the problem wouldn't be simple like a stretched clutch cable would it? It's a GTR, so it can't be a simple problem.....

Anyway - the car is off to the mechanic tomorrow, would like to just have some idea of what it may be before I take it there.

Cheers for your help! :laugh:

Argh. Sounds expensive. Do you know if it's a painful job and if it's expensive? :laugh:

You can do it yourself with a 12 & 14mm socket, a phillips screwdriver, a pair of pliers, and a rebuild kit for about $15-20 for each.

Piece of cake.

Hey guys -

We actually found that the clutch booster cylinder has split so there's an air leak there, so that's being replaced. Also getting my leaking ABS unit replaced as I assume the brake master cylinder also needs to come out of the way for the clutch booster cylinder to be replaced.

I hope there isn't a problem with the clutch's pressure plate as well :)

The GTR strikes the bank again ;)

Yeah what was the verdict I have the exact same problem, 1st and reverse are almost impossible which makes traffic lights interesting.

Can you let us know what it was, from what I have ready usually clutch related i.e worn cover, pressure plate or both. I'm running a OS Giken twin plate which has already been refurbished back in 2006, loooks like it's time again!

I had a similar problem with my previous clutch.

I had a leaking slave cylinder so had that replaced. When they installed it they didn't bleed the clutch fluid properly, I noticed it was a little crunchy on the way home when I picked it up but kinda came and went.

Had zero time to do it myself, and the workshop were too far away, so kept driving, clutch pedal kept getting heavier and heavier, hard to get into gears sometimes. Clutch wore out as it wasn't disengaging completely, then pivot ball snapped and fell out the bottom one day.

New clutch for me. Had a lot of other stuff being done around the same time so new clutch made sense anyway - thats how I justify it....

Thanks for the reply Paul, do you think having air in the system contributed to your clutch failure or would you say it was worn regardless?

I'll have a look at my slave and master shortly and see anything dodgy. My car is running just shy of 600hp so it's possible mine is just worn from use.

Nah the clutch was in good condition, was not too old and didn't go out in the usual way. It was either air in the fluid or the clutch fork & pivot were not aligned properly causing the crunch, and ultimately caused the pivot to fail.

600hp eh... yeah I imagine you would move through clutches fairly regularly. Better than gearboxes or driveshafts.

      There's more than one way to skin that cat, and most of the sump Maatouks have done will be GTR sumps. They are HUGE in GTR drag racing here.

      Yeah...I always start at the shift solenoids, because there's only a few reasons these will spook into limp mode, and bad shift solenoids is one ~ the other can be the shift control module (if you have steering wheel shift buttons)...it's easier to eliminate the solenoids first.

      Never ending fuel pump drama

      By cabramatta · Posted

      Might piggy back off this thread since there's been a good discussion about PWM.   I purchased a Walbro 460 F90000267 and have been looking into PWM to understand it. It was purchased more of a future proof as my original OEM fuel pump died (r33 below 200kw) and figured I'd just upgrade it to this. That's when it hit me that a pump this big can cause more dramas with such high amperage draw and heating of the fuel pump being on 100% all the time in such a mild setup.   I have a Nexus R3 and slowly collecting power mods but I was looking into the PWM feature on the NSP software:   Then looking at the graph from the fuel pump:     Am I safe to assume reducing duty cycle to 50% for example would make the pump run like a 230/lph ? Where does the PWM come in all of this ?   I've gone down the rabbit hole of PWM fuel pumps and it seems there are many differing opinions on how to go about it 😅

      Thank you, this will keep me busy for a bit.  I will update progression.

      That specific one would be an exchange part, meaning I'd have to send mine to them. Plus it looks like a non AWD sump, which won't work for me. There is one or two shops in my country that I can ask to do a sump extension job and it'd most likely end up being cheaper than sending mine to AUS or NZ and getting one back, and quicker too.
