LCR: have you crunched your gearbox when selecting i.e 3rd gear?

[J@mes]

full stage 2.
and the gear box oil was changed 2 weeks ago when I had my clutch fitted.

what oil did you use?

 

[J@mes]

just looked at the receipt of work done as I'm sure it said they replaced the gear box oil...

it said the clutch system was bleed thats all lol so my mistake!

my car is a 05 plate and has only just had its 30k service done (had it done at the same time as the clutch!)

as for what gear box oil to use, I think* uprated brake fluid can be used?! do a search if your after advice on what to use!

back to topic now I think!

My car had the 2nd to 3rd gear crunch, I changed the gearbox oil to redline MT90 and seemed to cure it.

I'm not calling you a liar at all, but I cant see how changing the oil would change it at all as we are talking about an ODD crunch when not being precise enough on doing a VERY FAST gear change if you see what I mean?! (especially when its from 2nd to 3rd gear only!)

I don't see how a short shift would fix this as said above, if anythin it would prob make it happen more often!
As its an even quicker shift than before and the revs loose than tiny millisecond they had to drop slightly!

Well that's one thing that doesn't plague the derv - revs are definitely not an issue for me. I find it easier to change gear with the short shift fitted because it makes the selection more precise.

When I was looking into changing the oil I came across this which might explain things, I appreciate the application is pretty different but the theory may be relevant in this instance...

Well basically you are, I changed to redline oil as I researched other forums such as tt.co.uk, vwvortex and a couple of others that I can't remember off the top of my head. They all said changing the oil improved the gear change and helped with the 2nd-3rd crunch.

I was seeing the crunch from 2nd-3rd at high rpm, not changing gear as quickly as possible...not into that as I think thats a very rough way to drive and is hard on the transmission.

Fair point although I would say to change at high rpm you have to change fairly sharpish before the revs drop off.

Me too. Happens 1st to 2nd and 2nd to 3rd when I try and make a quick getaway.

The change of oil thing is interesting.
