5 speed manual gearbox.

Post by Fox63 » Tue Jan 09, 2018 9:37 pm

It's been a long time sinse posting on here but I have a problem that needs to be sorted re my gearbox.

I have a 5 speed manual attached to a AWX engine, a B5.5 54plate model.

The gearbox has been a bit whiney for a while but has now reached a new noise level and the excitement of a potential box failure cant be far away. Any way...I figured...no a mate figured a while back that things may improve with a fluid change. Has anybody got info on which grade oil I should be using and what quantity I'll need.

Secondly...if the oil change doesnt make any difference and the box is goosed does anybody know the gearbox code for a replacement or does anybody have one knocking around at a reasonable price.

If it’s the original gearbox, it’ll be GGb at that ReG. don’t bother changing the oil, save it for an FHN box. Sounds like you have the same issue I had... mine eventually dropped its input shaft... Seem to be at least 3 or 4 GGB’s on here that have gone in the last few months. Bag of crp.

I take it then that the GGB and the FHN are exactly the same?

Dropped the input shaft eh! I take it that it was a bearing failure? I wonder if mine is the same. I always assumed it was the gears..maybe not!

I have had a whining noise from fourth gear ever since I bought the car. I changed the oil which slightly helped but it’s still there and has been for 25k miles. Second gear is always pissing me off. But that’s been the same with every passat I have owned.

It’s a FHN gearbox and seems good when the cars warmed up. Gearbox oil from the dealer with there so called friendly discount still cost about 45 pounds if I remember. But at the time it seemed the best oil to use. A few more options now I think.

They are the same but different. The GGB was post 2003 and made cheaply by VW. Mine failed at 130k and I installed a 165000 mile FHN with new oil which was and still is like new. Had a minor clunk into second when it’s been stood overnight but I think that’s because I put eurocarparts oil in it and not Fuchs Titan S or whatever it is... the older ones I believe were made by gertrag and were a lot better quality.

My GGB got gradually worse over 5k miles until the thrust bearing went and it started forcing the clutch into the flywheel... was a nightmare and sounded like a supercharger in 5th at speed hahahah.

Was that because the box was whining or just for the hell of it?

How many miles done like that? Not sure what synchronisers will say about that in long term, as ATF is more like hydraulic fluid, not really like an oil.

It was because I had the box out for repair and wanted it to change as smooth as possible. It's done 70k With it in, changed as scheduled maintenance for ATF again and it looked as good coming out as it did going in. In fairness put ATF in hundreds of manual boxes never had a problem but have cured a fair few!

Was actually the advise of arguably Yorkshire's leading manual gearbox repairer, works a treat! Remember having a mk5 golf with a terrible gear change, tried adjusting/resetting the cables made no difference, gave Stephen Briers a call they said the fully synthetic oil fitted at factory causes issues try put some mineral engine oil in (was very sceptical)! The difference was unreal felt like it had just had a new clutch in it, perfect the customer was over the moon! sometimes what you think would be better isn't.

Yep I know of a South West gearbox specialist repairer that recommends 10w40 in gearboxes

Very understandable on the 10W40 engine oil as the gearbox oils are a similar grade , the much higher normal numbers of 75w90 are just represented to not confuse the two .
