Christopher 0 Posted August 11, 2016 Report Share Posted August 11, 2016 Hi first off I will apologise if I am at the wrong section and I thank anyone in advance for any replies. Just serviced the haldex on my 4mo and all good.I want to change the gearbox oil and just wanted a little advise please. Have been told you need this mad socket to drain the oil is this true? Also I have been told the gearbox takes 2.8 litres which also feeds the transfer box. Is this correct or do you need to fill the tbox separately. 1 more thing.lol. TPS tell me gearbox and rear diff oil are same oil but vw say rear diff oil is different. Any advice would be greatly appreciated. Link to post Share on other sites
Liam_0404 5 Posted August 11, 2016 Report Share Posted August 11, 2016 Hi, some info from various places, hopefully will help you out...Rear diff - Holds 1.0 litre of oil and when drained is empty and requires 1.0 litre to refill it, handy as thats the size of bottle vw supply the oil in (Part No: G 052 145 A) For gear box oil im sure its 75w90 2.6 ltrs up front and 1 ltr in the rear diff, and dont confuse this withHaldex oil. thats a VW only thing and comes in a tube that you also need a gun for.
