S60 T5 - Aisin 8 speed

edward1946

Can anyone help me !! my 2014.5 S60 T5 has developed a problem in that the stop/start mechanism works one day and not the next. I have had the dealer complete a service on the transmission, replacing AF, also replacing the AT oil cooler that had developed a crack and was leaking a minor amount of fluid into the auto fluid. However the issue with the start/stop is driving me mad. When it is not working and I come to a stop, about 3 seconds after the stop there appears to be a slight thud as if the transmission is confused or is playing catch up.

Can someone explain what is happening and how to fix it - PLEASE

You need to read codes,

Thee is probably no such thing as "a minor leak" into the trans fluid and it may be toast.

Im just going by the older model and it wasnt good then……….

Didnt the dealer protest and say its hopeless? Take it back to them…..
