Sirspidey Posted November 9, 2016 Share Posted November 9, 2016 Hi all, some of you might know, I've just done an engine oil change to my 2005 WRX and it got me thinking about the gearbox and diff oils. How often should these be changed? Are they difficult jobs to do? The cluch was changed in January (before I bought it), should they have changed the gearbox oil then? many thanks Quote Link to comment Share on other sites More sharing options...
stants Posted November 10, 2016 Share Posted November 10, 2016 Gearbox and diff oil is easy, it won't have been done when the clutch was replaced as there's no real need unless you had a major service done ?? The interval is 3 years Iirc. Gearbox/front diff, there's a drain plug on underside of the box, remove and drain, as for re filling you have to use the gearbox dip stick hole underneath the intercooler, a funnel and length of hose is easiest for this. Rear diff there's a drain hole and a fill hole on the back of the diff as you look at it from behind, think they are 22/23mm plugs, undo the top one 1st to make sure it comes free, then undo the drain plug at bottom, Refute drain plug, fill via the top hole until it starts to come out the pop the plug back in again Sent from my SM-G930F using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
Linx Posted November 10, 2016 Share Posted November 10, 2016 I've had 30k miles recommend to me. I guess that is likely to be about 3 years too. Sent from my HTC Desire 530 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Sirspidey Posted November 10, 2016 Author Share Posted November 10, 2016 Nice one thanks guys. My car is at 54000 miles. Will check the service history and see if it's be done. If I can't find any info, I'll just do it. Well if 30000 is the make then it's pretty close to having it done for the second time anyway. Thanks again. Very helpful place. Glad I joined.

Sirspidey Posted November 11, 2016 Author Share Posted November 11, 2016 Gear changes feel fine. This is my first high performance car, excluding (back in the day) 309 gti, Astra gte etc, but first turbo car. so just want to keep on top of things.
