Hey guys,

I need a little help, my gearbox has been making some whining noise pretty much since I brought the car, my car went in for a service the other day, and the guys told me that my problem was the (input shaft bearing) or something. I always thought it was like my thrust bearing, but my old mechanic changed that and it didn't make any difference.

This is all in regards to my Rb20 box from my R32 gts-t.

Is this something that can be replaced??

Is it terminal, i.e like really bad??

Rough costs??

Would I be better of putting a whole new box in??

Thanks is advance for all your helps guys.

I was in a car running the same box and it sounded like it had a straight cut gearbox it was so loud. Mind you it was struggling behind a pretty stout RB25 engine.

Mine started makign a bit of noise so i dumped the Fuchs and replaced it with Castrol and it is now a bit quiter and shifts muc better.

Id be inclined to live with it, turn up the stereo. The cost of running around in circles trying to identify and fix the problem will drive you mad. Do the oil change and keep driving it...RB20 boxes are very cheap 2nd hand, or when it dies you can pull it apart and see if it can be rebuilt.

That said if you can remove it and strip it yourself, then go ahead, but if your paying someone...well:(

What Roy said. If it's only one bearing it's not worth it till it really really really gets noisy as it should do too much damage to the gearbox if it completely blows. I've had bearings completely colapse to the point of ball bearings coming out when I drained the oil and there was no damage to the box. It'll be ok for now.

Sounds like a bearing...If its making the noise all the time then it has to be a bearing that's always in use...So the input shaft would make sense.

GTR = money pit    This is indeed very true!!

Brand new gearbox, 100ks later it was making that whining noise. had it pulled apart after 10,000ks, nothing wrong with bearings, but there were score marks all over the input cluster gears!!!

      High temp brake fluid?

      By PranK · Posted

      In all the track days I've done over the past few months I've only had 1 issue with braking and thats with my current EBC pads (can't remember the colour, but they're not a track pad). I don't *think* I have had issues with brake fluid getting too hot, my understanding is that when that happens you will have quite noticeable brake loss - which I haven't had.  I'm using just regular ol' Penrite Super DOT4 fluid. I use this fluid in everything and my cars always seem to stop so I see no reason to change, except ... for the 335i. I need to do a fluid flush and was thinking about my fluid of choice and wondering if I should consider using something more high temp? Its not a super fast car by any standards but I'd hate to do a flush and then find myself with no brakes when I get. to Wakefield.  I guess, my question can be summed up as "How fast do you need to be driving to need higher temp brake fluid?"  I remember high temp fluid was considered a must have back in the day when I had my GTR.

      RB25DET in GTS4 R32 conversion

      By Jason Abell · Posted

      For anyone that comes here looking for answers on what can go wrong with gts-4 to rb25detneo swap. The Gloria's awd sump is different and does not fit. The rb25neo from stagea are exactly the same sump bolt pattern and axel alignment. Castings numbers are different on Gloria's blocks and oilpans if they need to be identified.

      RB26 AWD Sump / RB25 AWD Stagea Sumps - Are they the same?

      By Jason Abell · Posted

      I have information on this for anyone that comes looking again. https://www.facebook.com/share/p/18gsbFaYTU/ The rb25det neo from the stagea has the same sumo as rb26 and r32 gts4 (and other awd models). The sump that has caused so many problems during swaps are from the awd neo Gloria's. The casting numbers on the block and oil pans are different so this may help identify if you can't confirm where the motor came from

      Not feasible to fix the boot lid you had? Damage looked minor/hard to even see :p Source: Drove into something recently and you should be happy you didn't!

      Another new used boot arrived at the painters, it was sent back as there was nearly as much damage as the original one I want to replace  Finding a clean used boot lid is proving problematic, and I'm not keen on dropping $1500 on a new one from Mazda Sigh....
