Gearbox replacement update.

So, I've finally got the CD009 gearbox that I bought months ago fitted along with a new clutch and flywheel. The work was all done by H-Dev, and as I've come to expect from Jez it was all hassle free and on time/quote, so thanks again :thumbs:

 

The point was to solve a pretty bad 2nd and 3rd gear synchro failure, which happens to some degree on quite a few earlier cars. A few people wanted to know if this was a good option to solve a clunky gearbox so thought I'd post a verdict having now had the car back for a few days. First off the Exedy clutch feels VERY different to the knackered stock clutch; much smoother, lighter and more progressive.

 

The gearbox itself has been a bit of a mixed bag really. The actual shifting feels much better than the old box; It'll go smoothly into any gear with no clunking even from cold, so a good result there. However, it seems to have some sort of slack somewhere in the input side, which presents itself as a 'clack' sort of noise when you bring the clutch back up quickly after a gear change. It's definitely on the input side and not the driveshafts or diff because it happens in neutral too. Fairly sure it's slack because if I bring the clutch up slowly it doesn't happen. The new box came out of a 2006 rev-up car and has (allegedly) done about 23K miles, so i wouldn't really have expected it to be making wierd noises, does anyone else's 2006 car do anything like this?

 

Overall I'm calling it a net gain because even with the 'clack' the new box is still much quieter than the old one, and is much nicer to drive. For someone who uses the car as a daily driver, I'd say this is a worthwhile thing to get done as its made the car much easier and more relaxing to drive, but you always have to bear in mind that you're never going to know exactly what any pre-owned gearbox has had done to it in its previous life which adds an element of luck to it.
