Took the MX5 out to work for the first time since owning it yesterday as it gave me a good opportunity to really get used to it in some mixed driving environments.
When I got the car a couple of months ago I thought that the biting point was a perhaps a bit low to the floor and so I adjusted the pedal accordingly… The shift improved slightly but nothing groundbreaking.
Long and short of it, I’ve messed about with the pedal loads to try and find the right balance between not having the bite too high, and what will aid the smoothest shift.
So yesterday when I went to a meeting in Manchester (130 mile round trip), I opted to take a 12mm spanner with me so I could adjust it on the fly… Made a couple of adjustments before setting off home, all was well.
When I got home I pulled into the driveway and was about to reverse into the garage and when I put it into reverse the whole transmission and propshaft effectively slammed into gear… i.e. the clutch wasn’t properly disengaging, so the GB input shaft was still spinning and so yeah… Little bit of a grind, not a smooth engagement into reverse… No biggie… I adjusted the pedal again accordingly, the bite point raises, the clunking into reverse went away.
However prior to this on the drive home the pedal movement and bite were spot on and just how I like them, of course, using the forward gears only.
Now I know that reverse gears seldom have a synchro on them so a little bit of awkwardness is always to be expected, but I’m now considering whether it might be time to give it a new clutch… My reasoning being that although I’m confident the bite point was spot on yesterday on the way home and the changes were all as expected, the aforementioned reverse engagement isn’t ideal and I suspect that the clutch itself hasn’t quite got enough meat and grip to stop the GB input shaft spinning completely, hence the grind and clunk.
I’ve also noticed that the shifts aren’t particularly supple at all if I change gear below 3000rpm, more so when the transmission is cold… It’s always a little bit notchy, basically… though I can’t remember my last NC being like this most of the time.
A new clutch is -/+ £400 so I’m trying to decide whether to splurge on it or not, or whether it’s just a characteristic of this particular car and to just live with the higher bite point.
As a side note, there’s a minimal amount of judder when the car is cold, but this goes away almost completely when up to temperature after a couple of miles and changes.
What’s everyones thoughts on this?
2006 MK3 NC1, 67k. Has had a transmission oil change in the last 1k miles.
Cheers! (sorry for the essay, but detail is always key)
