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.

      R33 GTST Sh*tbox to Polished T*rd

      By Yeetus · Posted

      Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -

      Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.

      Some more close up pics now that I’m back to working on the car, the loop pile is nice but again haven’t compared it to the other types in person, it’s hard to tell from the pics on the website. View of the hemming on the edges too, it comes in 2 pieces - front and back, honestly very happy with it for anyone on the fence.  Also attached my previous pics from further up as it didn’t let me post them directly before. (Nothing worse than photo bucket pics that aren’t hosted anymore years later)
