Hi there,

Thank you for the donation,

These additives are not a cure all, at best they may just mask a problem, the slippage is a sign of worn clutch packs leaking servos or low line pressure, it really needs to be checked out now before you do some real damage driving it about, get it seen to by a qualified trans tech before its to l ate.
