Hi all

I just got done my 36k services at a shop, they did a full inspection, recommanded me to flush my transimission and powersteering fluids.
Is it necessary for 36k?


Thank you.

 

On a 2009, the ATF is SUPPOSED to be a lifetime fluid. No need to service it unless you have an issue with the trans. As for power steering, I believe its recommended every 36k, but I never changed mine until I built the motor and everything (I was around 70K). When I dropped the motor back in i flushed it and put all new fluid in it, however the old fluid looked fine. Up to you on that.

 

Does this also apply to the 2006 Models as well?

 

Isn't the first a/t transmission flush recommended at 120k? I think that's what the maintenance book says.

 

Heres the TSB on the WS fluid. TC's from 07-up used WS. 05-06 used the older T-IV ATF which followed a standard service interval. According to the TSB it should be inspected at 100k but never actually serviced/flushed. Funny enough, the trans itself didnt actually change. When I boosted my auto I drained the WS fluid, flushed it, and put in Royal Purple Max ATF which qualifies as a T-IV. It helped alot with the shifting under full throttle. WS is designed to be longer life and more efficient, but seems to not do to well in harsh conditions.
