Got some lingering issues with my 95 Nissan Caravan gearbox & have heard that some internals are interchangeable between the Caravan & Skyline/ Narvara box's. The Caravan box is an R55w71c
Also does anyone know of a Narvara box (2wd or 4wd) that is column change & could be fitted to the van.

What are the "lingering issues" ?

Gear wear patterns from unintended mismatch of parts. All the parts looked ok but clearly the wear patterns between them are not compatible after all
Random syncro snicking & random (mostly when cold) moderately tight to get in gear. Front bearing & or layshaft noise when stationary & clutch out (noise only there when the box is up to running temp/hot) Sometimes get temp locked out of 3rd when turning a sharp corner & changing in to 3rd at the same time. Changing down is fine It's a rebuilt box from many other parts but with all new bearings
Trying to find another box to rebuild or a set of internals that can be swapped over or a different model box that we can bolt in.

What oil you running? Your turning lock out sounds like a linkage/mounts problem rather than box internal.

Yea a little hard to confirm because . well you know . turning AND changing gears isn't the simplest thing to do with a really short 1st & 2nd gear to get around large corners in town ;-)
3rd gear cluster has a bit of end play that you can feel with the gearshift when on & off the accelerator. The other gears don't move the lever.

Oil is a 75/90 grade.
The growl is what you would expect from a shot front /input shaft bearing. Goes away when you put your foot on the clutch. Brand new full clutch kit

So driving a twin stick with a steering wheel as big as the moon is easier?

LOL, anything thats not working correctly is a hassle when using it in awkward places

Mrfixit. mate you should have gone for a 2nd hand box in the 1st place like I suggested. $250.00 and it's condition would have matched the rest of the van.

Hadn't been able to find anything even remotely like that price & certainly not in reasonable condition. Unbeknown to me at the time of purchase, theses box's are like hens teeth on a bull farm

It was about the time you purchased the Gypsymobile that I'm sure I saw at least 3 at the Pickapart yard in Takanini. There was also a 2.7 Navara and Atlas that would have been useable.

My Navara box has done 900,000km and howls like a banshee. On 1st shift into 2nd it balks when cold. 3rd syncro is getting easy to beat but other than that its fine. The oil sounds about right - is it GL4 or GL5? I've got the owners manual somewhere so will see what the factory recommended. I read somewhere that the internals of the floor change and column change boxes are the same. If thats the case then any ol box will give you the bits to rebuild it again. Are the linkages adjustable? If so maybe they not quite right. As for the grumble I'd just live with it - turn the stereo up!

LOL, bit of a stuff up on Nissans part on theses box's.
"As for the grumble I'd just live with it" *Cough* . yea thats what the last owner did & it broke the side out of the main front bearing/ welded a cog bearing sleeve to the main shaft/ lumps fell out in the drain pan when the oil was drained/ the crud going through the tail shaft bearing also grooved the driveshaft yoke AND . yada yada assorted other damage. The dang thing tried to jam up on the way back from Jaffaland.
Oh, & it was by that stage totally pointless to use the radio

Well if it's all new bearings then it shouldn't be a bearing that's rumbling. Sounds to me as if the 1st box didn't have any oil at some stage. How loud is the grumble/rumble in your "new" box?

No idea on how the box was maintained before me except that it appears that the van has only had whats needed to keep it running. The old box was full of oil but even if it had been run out, then I don't know how because the box & underside of the van was reasonably clean of any signs of a "drainable leak" for anytime in recent years (as in many years ago) As I said above, the grumble thats there is what you would expect for a shot front/input shaft bearing., no noise when clutch pressed in but noisy when clutch out (not in gear) Easy to hear over the engine idle noise (it's a van, so you are pretty much sitting on top of it). Complete new clutch kit fitted. No noise when the box is cold but definitely there when the box is hot. We are suspecting a wear pattern mismatch between the main gears & the lay shaft.
