Hello fatz, Thanx for the info.
Looking at the oil thats in it, the receipt says its 2.5 years old now.
And ive noticed that it only happens around 15 mins or more in to driving. When its cold it doesnt seem to do it.
And I have been doing gentle shifts, it still resists very slightly but no massive crunches.
Thinking about giving the shockproof a go because im thinking when oil gets warm, it thins out. Maybe this is why it doesnt happen when its cold?
