I have an Impreza 2.0L 4AT 2008 at 100k mark and the gearbox is acting up: slow to shift, rough shift, vibrations on D when stopped. Inspected the ATF, level is good, but color is weird: clear, slight yellowish, almost just like fresh engine oil. Likely wrong oil was replaced by someone before me. Also manual states that vibration can be caused by higher viscosity ATF (dexron III instead of VI). The manual also list possible mechanical issues causing the delays, but let's try flush first. I know there are different opinions, flush vs. drain, let's not discuss that here. I decided to do a full flush. Now I was searching the internetz how that could be DIY'ed... And oh man, some people are brave. In other words, I did not find a safe way this could be DIY'ed without fancy flush machine that only large specialized shops have. Did I miss something? Was even thinking about making a special pump myself. -
93 Legacy - New timing belt & water pump, Tune-up, Intake system cleaned, new filters etc. The car runs much better but still seems auto trans is sluggish. No real hard shifting or slipping but lacking umpf. I would like to change the fluid and filter screen & dont want to have a shop do it- prices are high, employee's are inexperienced, parts and performance lack workmanship & quality. I want to Drain the whole system not necessarily flush it, just get out all the old fluid out & replaced. I have searched on "how to do it yourself" & have a general idea of what to do. Take one of the trans cooler lines off to pump out the old fluid that isnt in the pan, Drain & remove pan then clean it out & remove old gasket material/residue, replace filter/screen gasket & trans pan, And refill with ATF. More or less this is the "How to" I found but very simplified. I think pumping/draining out of the cooler line would be done before the pan right? Would new fluid need to be added while pumping out so system doesnt run dry? I'd rather not run a bunch of new fluid in it just to throw it away. I would like to know if anyone has done a flush or drain the whole system at home & what procedure(with details) was used, problems or issues occurred, *lack of a better term* "Tricks"/techniques to use. What brand ATF is most commonly used by members? Any bad experiences with NAPA brand/Or similar ATF? What is a good way to clean trans out before adding new ATF? I was thinking about adding SeaFoam Trans Tune to help clean it out. Anyone used SeaFoam Trans Tune (not regular seafoam) before? Also read that Trans-X has been used & recommended by quite a few subaru owners in their auto's to help or prevent issues. Add SeaFoam Trans Tune drive a few miles, drain & replace with new fluid and Trans-X additive, what do you think? Any & All helpful information or ideas and opinions are appreciated, hope to get replies/responses ASAP, Thanks.
