I have an IS200SE, it always used to judder in 1st gear and 2nd gear change was not 100% smooth, also the engine seemed to scream when driving (like Supercars do) around because I had to use lots of revs to get it to feel like it had any torque (felt to me like the car was too heavy and the engine underpowered). Anyway, I asked dealer to take a look under warranty, they looked at clutch performance and said there was no problem at all, but when I drive it now, it's a lot better (gearbox and pedals are stiffer and much, much less judder).
So I told the dealer, its much better now, now it just feels like it wants to judder and judders a little but seems to be holding back. Again, the dealer looked at it and claimed there was nothing wrong. But the gear changes are pretty much spot on now, and it feels like it has more torque also and the engine is no longer 'screaming' with revs, seems pretty silent in fact.
They are doing somthing with the vehicle but not telling me, I asked the dealer - have they tightened anything etc. and he says its all hydraulic and you cannot adjust it - it either works or it doesn't
Instinct tells me the dealer is trying to BS me, any ideas on what could be the cause? And would any after market accessories like a lighter flywheel cure the problem? B)
