Should I do some preventative transmission maintenance? Servo cover? ATF flush?

[jaxon175]

Hi all,

Recently purchased a 2001 S60 with 125K on it. Doing my research I learned about the time-bomb that could be my transmission. Just to preface, I have had no trouble at all in the past 2 weeks of ownership with hard shifts, flaring, or any other symptoms. However, I would like to avoid any trouble in the near future.

Going through all of the old service documents, I saw no mention any ATF changes. I have also read about the updated b4 servo cover. I went ahead and ordered the servo cover from IPD ($30, why not?) and a full flush kit. I have my 14 qts of Toyota T-IV ready to go for a full flush.

My questions:

1. "If it ain't broke, don't fix it" - Should I even be messing with any of this right now as I have no current complaints?
2. Should I replace the servo cover just to be sure I have the updated one?
3. Should I do a full ATF flush or just drain the gear box and refill?
3.1 My initial thought was to do 2 or 3 drain and fills in the next 10k miles, then do a full flush. Is this a good approach?

Thanks!

1. it's not broke, but you're not fixing it - you're doing "maintenance"
2. don't know
3/3.1 either the full flush through the cooler line or a series of drain and fills followed by a full flush would be fine. The latter may be "safer" but I doubt that it will cause any issues. I would just do a full flush now, then again in 30k miles or 2 years.

Don't do B4 servo if it works.

You didn't mention how dirty is ATF.

Absolutely...drain/fill & flush, and get another case of atf oil to over-kill it. Nothing better than seeing the old, black oil turn cherry red!

The trouble rate on the transmissions is something like 10%. Remember that a lot come here when they have trouble, so it looks much more bleak than the whole statistical picture.

Drain and fill 3x and drive it sedately
