Crunch on octavia gearbox when cold

[rachris]

Does anyone else have this problem???.. My T reg 1600 Octy lx runs like a dream and I love driving it, (Much more comfortable and smoother than the tdi110 that I have), But when It is cold the gearbox crunches when I go from 1st gear to 2nd, It goes into 2nd easy enough but with a slight crunch, But If i take it slowly and gently it wont crunch. When the car gets warmed up after say 2 mins It no longer crunches at tall. The car was previously owned by an elderly gentlman around 70-80 and does run well. Is this something to be concerned about as It is a 2nd car but I intend to keeping it for sometime as its only got 76k on the clock and only paid a grand for it!! Anyone any ideas??? Is it a common fault on this year octy?? Many thanks Chris

My vRS did this untill I changed the gearbox oil. First to second was the worst...

It only does it from 1st to 2nd and only when cold, I havent changed the gearbox oil I thought they were sealed for life (as such), I have bought some molyslip to add to the gearbox dont know whether that will work!!

Mine did it when cold too, it was a sod to change without crunching. When warm it was a dream. Change of oil sorted it out no problems.

Same 1st to 2nd when cold problem here too

Are there any recommendations on which is the best gear oil to use for this box as im changing mine at the weekend ?

I changed mine with Millers TRX fully Synthetic gear oil.

Made a good difference too, and I wouldn't bother with the molyslip myself.

Also don't forget some gear linkages are wires which stretch over time and may need adjusting a little.

In the first place the gearbox isn't "sealed for life"; there's a drain plug on the underside.

Secondly do not put Molyslip (or any friction reducer) into a synchromesh gearbox, because they rely on friction to synchronise the gear speeds.

Finally, when changing, use a good quality EP gear oil. Cheezemonkai's already made a recommendation.

Mine doesn't crunch but can be clunky between 1st & 2nd. I put it down to it being cold, after a couple fo miles it's fine. Don't notice it so much in the summer only the winter.

My 4X4's gearbox has had and still has a similar problem since I bought the car with 1500 miles on the clock.

My does this intermitently - I booked it in at the dealer fot them to look at it the other week but when the day came it was fine so I called to cancel. 2 days later it was the same again. Might have to get it booked in to be checked after all...

1st to 2nd is and has always been a pig from new on my 4x4. Took it back a couple of times - oil changed twice (once told by main dealer that another main dealer had put the wrong oil in:thumbdwn: ) adjusted cables, gets better for a short while then just the same. I was going to get more stroppy but I tried a different 4x4 and it was worse:eek: so I put up with it. Odd that they dont seem to like going up but coming down the box is no problem.
