Hi. i'm having a problem with my 530i with a zf5hp19. It goes into lockup way too soon, when coming out of a 90* turn, i'm in 3rd and it immidialy locks up and i have too push the accelerator hard to get it to downshift. It only happens when i barely touch the accelerator (city driving) works fine when i'm accelerating in a straight line from a stand still. Anybody else expiriencing this?
