My gearbox has started to crunch slightly when shifting into 3rd gear at high revs (looks like the 3rd gear synchro is wearing). It isn't a consistent crunch, it seems to be becoming when the gearbox is warm (running for about 20minutes), and even then if I take it into neutral and then 3rd it doesn't crunch. However if I try take it from 2nd to 3rd or 4th to 3rd quickly at medium to high revs it will crunch.
ATM I have a selector seal leak identified by Renault, (also a common problem I realise and can potentially be fixed DIY with a JC5 gearbox kit), so I'm going to service the gearbox oil (Trans Elf NFP 75W80 ~3.1L) and hope that this fixes it. I am especially interested in how much oil will come out and if/how much filings along with it to see if this was the cause.
I understand this is a common problem and there are many threads addressing this issue, however I would like to know what to expect? Are the non-esp gearboxes in the Mk II Ph II Clio Sport 172's relatively weak or is it just my luck?? How long do I have left before it needs replacing/reco (months, year or years)?
Also is there a particular cause or is it a common problem due to being a bad gearbox, or is it due to its design making it prone to leaks therefore potentially reducing the gearbox oil level and hence wear.
Regardless, what else can I do to ensure the gearbox lasts as long as possible in terms of driving style etc. I really really do not want to overhaul a gearbox atm as I am in no financial situation haha :dapprove:.
