Clutch/Gearbox Problem

I get problem sometimes when I have to select reverse. When I try putting the gearshift into reverse the stick sometime refuses to go in and if you try forcing it you hear a grating noise. To get around the problem have to put the car in neutral, try selecting one of the other gears and then shift into reverse. The problem is intermittent and is becoming a worry. I was wondering if the gearbox might have a problem with the reverse gear or if the clutch pressure plate might need adjusting or realigning.

u know that wen ur slowing down u downshift but if ur going too fast u cant get into 1st , same thing with reverse i think maybe try stopping and then selecting reverse, if it still happens u got urself a problem, but if its all ok, will save u some money for a while atleast until u rectify the problem eh?

i had the same problem. box was too "crunchy" and it wouldnt accept the gears sumtimes. Wack sum redline shookproof into it lads. that will help for about 30,000 + km. ive done about 30,000km on it and its been sweet. onli problem is that i can see the problem startin to come back a lil bit. But its still better then wat it was. I find that if i thrash my car then the box isnt too forgivin and will play up for a while til it starts to relax a bit. If ur g/box wont go into reverse. try pumpin the clutch a bit as well to get sum oil flowing thru it, works a charm everytime.

Thanks for the info guys. I will continue doing the N to reverse shift process. In the meantime I will source a clutch assembly and look for a replacement box. Does anyone know where you can get rebuild kits for skyline gearboxes, particularly the FS5W71C gearbox?

Well, i've had my gearbox out of the car, apart, and the place wanted $1300 to rebuild it (change bearings and syncros) now thats with the box out, and split open? what a joke. So i went and got new bearings for like $200 all up and did it myself. You wont be able to do this unless you know what your doing + have big arse bearing pullers.

Rebuilding the box is almost a waste, unless your running big HP your better getting a 'newer' second hand box.

That is the nature of most gearboxes that are built strongly enough to take some grunt from anything other than a sub 2 litre econobox.

Jump into a LandCruiser and you will quickly become acquainted with the difficulties of selecting 1st gear without matching revs to the road speed. Try blipping the throttle slightly to bring the revs up as you select 1st. Done right, you will get it to slide in.

Generally you should find that either lighter weight gear oil and/or whether the gear sets are at a proper operating temperature.

      Thanks Santa (the neverending trials of the 400,000klm, 400kw, RB30, manual swapped Stagea)

      Thanks Duncan! Yeah it's street use for me only. Maybe occasional track day. Any difference in noise when running with the two pumps? I would expect the lift pump to be more quiet than the main pump so hopefully not? And yes, unfortunately quite a big price difference to the simple hanger setup. Though I'm usually willing to trade money for better reliability and future-proofing. Buy once, cry once and all that. I'd be very happy to never have to deal with fuel pump / wiring issues again

      The old manifold was quite under the GTR strut brace.  The new manifold is quite [unknown] the GTR strut brace. The GTR strut brace was needed to clear the bonnet vents. The Old strut brace will almost certainly clear the new manifold, but not the bonnet vents. The old strut brace will almost certainly clear the new manifold, and the new bonnet without vents. But I am hoping the GTR strut brace clears the new manifold :p

      Bonnet clearance?

      On the bright side, at least you knew that it happened and remedied before anything happened. A friend of mine just took his Fiat 124 to a shop for an oil change and they didn't tighten the oil filter housing properly. 4.5 quarts spewed out and even after refilling + tightening the cap the engine has a tick now.

      So, more pain. The FAST manifold is a little larger than the stocker. This is problematic because there really wasn't much clearance to begin with, so going from 'barely enough' well into 'no' is sad based on the external dimensions of the thing, even though where it bolts to the head is the same. Result is the fuel rails sit a good 25mm higher, and this is a bit of an issue with the wiring that runs behind the motor, and the fuel lines, and everything else. When pushing the manifold on, it required a huge amount of force to crush wiring looms to fit it, sensors like the MAP sensor are about 1mm from the firewall, and the FPR just has to bend ABS lines to be forced into place. After some brainstorming and some sad drinking, the loom for some reason ran from the grommet behind the ABS sensor, then to the driver side head, then back to the passenger side head. So all of this was pulled back and stripped, a few wires cut and rejoined, so that the 'branch' was now on the passenger side's head as below: Before you basically couldn't see anything behind the driver head. This is much improved! The MAP sensor is now pointing up (instead of at the firewall) Brackets have been made up for the rail. The rails are for a LS1, the manifold is designed around a LS2 as it's base. Which of course has slightly different bracketry and water pump clearance, hence the mods people need to do. Should be hopefully mounted tonight. I spent money on a new FPR that is slightly more compact than my Turbosmart FPR1200. The gauge has also been moved to the rail. There's also apparently an ORB to AN Union instead of the adapter, because the ~25mm of the current adapter is going to make the difference. Provided this all goes together and arrives today, it'll be the totally not stressful attempt to start it.
