Should read 32psi not 31psi and I've switched back to sport not sport + because every so often the gear changes are just so brutal that mechanical sympathy gets the better of me.
It's good but not brilliant, if you want to get the most out of your 43 i'd certainly give the manual option a try. Why have a V6 with loads of torque if it just drops a gear or three every time you accelerate moderately. Anyway the gear box bit is only a small part of the driving experience, sports suspension and sport handling mode is worth trying even if you want to let the box do it's own thing.All sounds a bit complicated to me, auto box is brilliant, no need in my opinion to drive it in manual.
Better auto than my previous Audi although I had no complaints with that either.Have tried ALL the settings but the car choosing the settings in comfort mode is my normal drive except for rare occasions, does all I want of it. If you don't think the gearbox is brilliant have a drive of an auto discovery sport.
Been on the MB forums over 18 months and not heard a bad word about the GLC auto box.
