Its hard to explain really,i've been told that the gearbox has a hot and cold program,the cold holds onto first gear for longer ? The bogging down issue just seems more of an inconvenience than anything,the car will shift upto second but then seems to shift up to 3rd too early at too lower revs causing the car to labour quite a lot. I don't seem to have any of the other issues that people on here seem to have, there is no harsh up or downshift between 1st and 2nd and i have no delay going into reverse. The box works fine in sport and manual modes.
