See how it goes I reckon Link to comment Share on other sites More sharing options...
Vevapower Waiting for the 1st N/A 12! Donating Members 2,533 Member For: 17y 6d Gender: Male Location: Sydney Posted 20/08/12 06:47 AM Share Posted 20/08/12 06:47 AM (edited) Hmm I'm not entirely convinced that the wheel thing was the issue. Go for a 30 min drive and then try wot 3rd 4th. And get back to us.But hey if it was this uneven wheel thing then you have dodged a bullet somewhat and good win.

I find that a 3% difference in rolling can cause this problem is mighty strange but hey, I'm no mechanic! Link to comment Share on other sites More sharing options...

nelsonian101 Donating Members 961 Member For: 16y 7m 23d Gender: Male Location: Sydney Posted 20/08/12 09:36 AM Share Posted 20/08/12 09:36 AM I have a bad feeling this is what is happening to my ZF.(Can't be too hard on it as it's done over a dozen circuit days and 175,000kms!)Change from 3rd to 4th often delays at full throttle on the circuit and find I have to back off a bit to get a smooth selection.Genuine ZF Oil, Larger heat exchanger, Coolant and ZFfilter changed every year or 45,000kms approx.Not found a need to join the "Milkshake Hysteria Wagon" with a Cooler. Have an engine oil cooler instead.Listen to change at the 10sec mark. It is now a lot worse and has an even longer, high rev duration period before selection 4th. Where do I get this fixed in Sydney and how much approx?Car has 350rwkw and a lot of torque on the small FG turbo and e85. Link to comment Share on other sites More sharing options...
