Hey all!

 

I need to do a tranny flush and I haven't done it on my soob before..any particular brand/weight I should use??? I have an 03 wrx..manual of course!

 

I was just going to call Subaru service center directly..but thought I'd check here first.

Well if your looking to use exactly what the Service dept uses at the dealership...I can tell you we use 75w90 Valvoline standard gear oil..that's what I have in my gearbox in my 02 WRX..Of course Ive heard good things about redline..

+1. The Valvoline is an excellent product, but some of us swear by Redline 75W90ns:

Manuals get a simple drain and fill- automatics get the flush. 75W90 is what the manual calls for. I personally don't have much of a preference, but Valvoline is typically good stuff. Every brand has to pass tests to be certified as gear oil, though, so it's all a wash in the end. I would take a good look at synthetic though, it's quite a bit thinner with higher protection. Makes for better mileage and much better shifts.
