Go to a motorfactors (Halfords or Joe's parts)give them the reg of your car and they will tell you,Simples,that's how we do it up north.Most people don't put in the wrong fluid so most people won't be able to tell you " what effect does a wrong transmition oil have on it".On a lot of cars the fluid is in for the life of the car why mess with it for tuppence.
