Just (about two hours ago) bought an 04 xc70 with 80K on the Odo.<br>I negotiated the price down by the cost of an ATF change (on top of any other negotiating) So they would be paying for it. Question is (yes there is a question)<br>@ 80K is there anyone who thinks an ATF change will be detrimental (by stirring up funk)- volvo dealer also told me they would, but don't want to, change the ATF, it's my call.<br>Going in I thought it was mandatory, but is it better to let sleeping dogs lie?<br>Or maybe a partial change, like honda recommends (3 out/3 in every 30K) so as not to shock the trans, and stir up the funk?<br>I plan on running the wheels off this one, I don't pick the car up until Friday, so I could have them do it tomorrow.<br>Thoughts?<p><br><i>Modified by Q-Ship at 3:18 PM 6-10-2009</i><BR><BR>

Re: Didn't want to hijack Coconut Pete's thread- Re ATF change (Q-Ship)

It's one of those things people have strong opinions of. Few have the data to support either way.<p>This is my educated opinion: Drain and fill just gives you fresh additives; what could possibly make the transmission act up after it? Flush with engine power (not power flush machine) is the same as running the transmission normally; it can't get the gunk moving any differently. Fresh additives could be thought to wash the gunk off and get it moving so maybe that's the mechanism that created this old tale.<p>To me personally, salvaged AW55 transmissions are cheap enough already for me not to worry about it at all. I'll throw in another one when it finally blows. You're supposed to drive a Volvo for 1000,000 miles and there's gonna be some maintenance required on the way. <br>Cheers <IMG NAME="icon" SRC="http://********************/smile/emcocktl.gif" BORDER="0">

Re: Didn't want to hijack Coconut Pete's thread- Re ATF change (Mika)

Mika,<br>Thanks for the reply. I was suprised no one had an opinion they'd share on this. I think I'll just buy the fluid (yes correct one..) and do it myself, pocket the $100 difference I got from the dealer. Personally I think it is better to change, but wanted to hear from anyone who could coherently argue not to do it.<p>In a forum for my wifes oddyssey, to facilitate trans fluid changes (2001-2003 oddy trans had a high fail rate too) some would install a petcock (get your giggles out now..) to eliminate the need to disconnect the hoses, and make for an easier job. I might do that for the XC.

Re: (Q-Ship)

Funny...... what I did not say in my thread was that I'm in the same situation.<p>My 2001 has 110 K on it and while i'm not 100% sure I am pretty sure it's never had a fluid change.<p>I've finally decided after much reading to go through with it.

Re: (Q-Ship)

I say do it. I did it (and I am NOT a mechanic) to my 04 with about 95K on it. The old fluid came out very brown and I could plainly see when the new fluid started coming out (nice and red). I changed all fluids except brake, and that's getting changed soon when the new rotors/pads/ss lines go on. I can't say for sure that the new tranny fluid has helped (but I think it has), but I certainly haven't gotten any bad results. Fresh, clean synthetic fluid everywhere has got to be better than old, dirty, dino fluid. JMO.

Re: Didn't want to hijack Coconut Pete's thread- Re ATF change (Q-Ship)

IF the trans is shifting fine, I would do 2 or 3 drain and fills. within 5000 miles between the 1st and rthe 3rd.<br>Personally you could do three with only 200 miles in between each one

Re: (Q-Ship)

Q-Ship: You can ask them to Merge, I suppose our topics are kinda blurring together.<p>I never got my second key programmed so I have to get that done and get a recall done on the ECU, I suppose I might as well as them for any tranny updates while I am at the stealer.<p>My tranny shifts fine, it just seems to slip between 2nd and 3rd from time to time, but shifting is fine.

Re: Didn't want to hijack Coconut Pete's thread- Re ATF change (Q-Ship)

I did my 01 V70 T5a when it had 70K miles and the fluid was only slightly dis-colored. Performance wise there was no change with a 12 quart drain and fill at 2 quarts per drain (using the return line from the radiator). I'm planning on doing this again at 100K, and every 33.3K there after. Currently the trannys shifts as good as new. Yes, I'm the original owner and am now at 98K.<p>Jerry

Full vs partial, based on color/smell is what I think I'll do...

If the fluid looks stable, red and does not stink I'll do the full change.<br>If it seems toasted I'll do a 3 part staged swap out. That way I'll slowly mix in the new if the fluid seems unstable.<p>What's anyone think?

Re: Full vs partial, based on color/smell is what I think I'll do... (Q-Ship)

i just do a drain and fill about every 20k miles on both cars. that is what i have settled on. the v40 with 87k miles has a trans fluid that looks fresh pink. it smells as new, no drama.<p>we do not tow anything. we drive fairly spirited, it is california.<p>i use mobil 3309, though a friend who owns a shop uses toyota type 4, which is the same, but easier for him to get.<p>good luck.<p>for the v70, under warranty, i do use the 4 litre volvo packed fluid. i bought a few 4l jugs from volvo a few years ago.

I just did the 12 pack drain and fill routine last weekend at 78K. The car shifts as well as can be expected.

Re: Didn't want to hijack Coconut Pete's thread- Re ATF change (3g3t7i)

Exeter huh?, I'm in Birdsboro. What'd you use? Mobil 3309 or another? <br>I did 6 quarts <I>yesterday</I> with Castrol. Read that adaptive transmissions can act up when shocked with new fluid, due to the change in fluid characteristics. Not necessarliy that the new fluid stirs up funk. So, since I'm at 83K, I spread out the full 12 qts, I'll do the other 6 in a few weeks.<br> I did mine with 10' of trans cooler hose (better to handle the hot fluid) and a homemade fitting. I'll have to post a pic of the fitting. It's pretty slick, made from a plastic "cork", like that of a cheap champagne. But it fits snug with barbs, and allows the tubing to be coiled up and plugged end to end (so residual fluid does not leak out)
