Am looking to replace the JNC Code gearbox in my Fabia vRS SE to the earlier "long box" Code FSM. I need to do this as the longer gearing helps my learner drivers (I'm an instructor) plus the fact that I do thousands of miles a month on the motorway and I need that "long" sixth gear. I have been quoted £1200 plus VAT for a new one, but does anyone have any idea what the JNC box would be worth so that I could claw some of that outlay back. The car it's coming out of is the Special Edition model (2007) and only has 23,000 on the clock, so virtually a brand new box for somebody???

Any ideas or estimates anybody????

What sort of milage was the gearbox on, and how much did it cost you to fit?

No idea on milage although was assured it was from a average miler 2006 with a rear end shunt so i assume 60k max

It was a gamble although i was quoted scary money for rebuild as most garages wouldnt do it until i commited to clutch and flywheel due to mine sitting at 80k

I found a great mechanic who had it delivered to his garage and fitted it for £200

I have already used him again (cambelt kit and water pump, oil etc) his honesty and willingness to help will get him a fair bit of work

6th gear is the only difference.... tbh i wouldnt bother... by the time you pay for it how long will it take to recoup the mone back in better mpg?? i'd be suprised if you could even recoupe it lol

Let alone really notice a significant difference.

First and second gears are considerably shorter in my 07 car than in my 04 one. If it was only sixth gear different, I wouldn't bother. First is so short, you can pull away from a standstill on most occasions in second. Hate it! Don't know why they changed the boxes, the original one was brilliant, and that sixth gear is a beauty on the 04 car, purrs along at 2500rpm at 100mph+, the 07 car is revving it's nuts off at that speed!!!

I have to agree, and I own one of the later boxes, your talking 3,100rpm @ 100mph whilst they earlier box sits at 1,900rpm @ 70mph which is awesome...

Its not just 6th that is different, 4th is a big gear and is different too!
