what do i need to buy to fix?
My 2006 bmw 530xi slips in 5th gear when i hard
accelerate, the transmission malfunction light is on,
but it shifts fine 1-4. light only comes on when i
HARD accelerate in 5th or 6th gear. Please help! it’s
my first bmw, i got so excited and then this
happened, hopefully it’s just a gearbox or low fluid
and a bad filter...
