I also have a RS200 and I have just picked it up from the garage this morning, yes new gearbox at 37000' signs are as everyone says crunching especially in 3rd and 4th during swift gear changes, mine was out of warranty even though the problem did start when it was under warranty my own fault for not recognising the signs sooner it got progressively worse, anyway I contacted renault and to be fair they have been ace I ended up paying £512 for a new box replacement the actual cost at a dealership is £2356 so although I'm miffed about having to have a new gearbox I'm also happy it only cost me what is it did, if this car costs me anymore I'm going to burn it, saying that I'm still of the opinion that it should not of cost me anything as its a fault, I'm convinced if you drive this car how its meant to be driven the road car version the one we all buy the gearbox will fail if you drive like a granny it will probably last but driving like a granny is not what this cars about I'm hoping to fall back in love with it if not I'm outta here so to speak,
These cars should stand upto track days aggressive driving high revs without anything failing to be fair as that is what they were billed as.
Thanks
