OK, the car is with the dealer as I write this. Miraculously, the car did it to the guy who test drove it, how often does that ever happen?! They're gonna keep it for 'a few days' and see what's happening and also get advice from fiat.
In the meantime, I have a bright yellow 500 as a courtesy car. It'll be sods law that we get loads of snow now I have to say, colour aside, I'm not fond of the 500. Steering and ride are not a patch on my panda, I'm not a fan of the overly stylised cabin, visibility is significantly worse than my car and it's a good job I ain't going anywhere as there is no space inside for anything. I'd like to say what engine it is but I don't know. Could be the 1.2 as sounds familiar but it felt pretty gutsy so maybe a 1.4. I miss my 2 cylinder! And why did it have to be yellow!
So far, very very good service from the dealer, let's hope they keep it up.
Alsation1,
Many thanks for the update on what's going on with your car. Having EXACTLY the same problem as you - albeit my car being the 6 speed 4x4 Twinair - I am VERY interested to know what the problem is with your car and especially what the fix is as I'm likely to be going down the same route as your good self sooner rather than later.
Boy oh boy are these forums a great place to share info!
I can totally avoid the slight graunch going from 5th to 4th if I go slowly and deliberately through/across the gate during the change or blip the throttle a bit as I'm clutching/changing. But I can readily make the issue occur if I push the clutch in in 5th, let the revs go down to tick over (like one arguably might reasonably do coasting towards some traffic lights or such) and then go for a fairly swift change down into 4th.
Please do keep me (and the rest of the crew here) as to how things proceed from here with your car as regards diagnosis and repair.
Best regards,
Mike
