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.

      The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
