Need advice had some work done at recomended indie which included auto box filter and oil change.This was done apparently and 7lts and new filter replaced,however garage said the torque convertor cant be drained without dropping gearbox and the old oil was very dirty so they advised in that in about 200 miles have it changed again to ensure all oil cleaned out and another new filter might be needed.
Anyway 100 miles or so later autobox not changeing well,so a neighbour who is a mad bmw nut said he would check atf level.The level was low and he said the oil hadnt been changed and to prove it he pumped out about 1tr of thick black burnt smelling atf fluid via dipstick and we then topped it up to correct temp level at 80 deg.My question is should the atf fluid be this condition after 7lts of new oil put in 100 miles ago or can this be the old oil caught in the torque convertor but surley when the oil is refilled its done via the dipstick and so it shouldnt be like treacle or have i been had over by the garage ????.
