Its not jerking or kangarooing when driving up a hill, or when rversing for that matter.
the issue I thought I had was that when I was doing around 30-40, and had to slow down to 10-15ish mph for a corner, or a slight junction that you could just continue at providing there wasn't any traffic, id slow down to the 10-15mph, and then want to speed up again, and I think I was accelerating too hard, so the car would jump to 1st gear to get the power. it would lurch because once id let off the power it would quickly jump back to 2nd/3rd gear.
