Replying to: torme (Jan 07, 2009 2:17 pm) Here is a discussion of transmission issues: http://forums.swedespeed.com/zerothread?id=113477.   Concerning the cooling system, in your post referenced above, you did state that you got a cooling system flush. And you also state that the defrosting performance is not good, as well as there being an odor. One effect of a leaking heater core is that volatilized ethylene glycol (the main ingredient by weight in the antifreeze) condenses on the insides of the windshield and on the windows as an oily feeling film. (Wipe it with your index finger and then rub the finger and thumb together.) This would definitely be classified as poor defrosting performance.

Replying to: jim314 (Feb 18, 2009 12:09 pm) I'm confused.... the discussion you referenced seems to be talking about engine oil. I was referring to transnmission fluid. Does anyone know if the Mobile JWS 3309 is synthetic transmission fluid that is compatable with Volvo V70 2001 2.4L? I can't believe the price the Dealer is asking $210 just for the fluid!! I love the car faces thanks, Arlene Replies to this message: jim314 (Feb 19, 2009 6:21 am) jim314 (Feb 19, 2009 7:07 am) fedlawman (Feb 19, 2009 4:45 pm)

Replying to: sheraotwp (Feb 18, 2009 10:22 pm) One person in the discussion referred to "oil", but he was not referring to engine oil (aka motor oil, which lubricates the engine, or just oil). He was referring to automatic transmission oil, which is nowadays usually called automatic transmission fluid, usually abbreviated ATF.   In the discussion these seemingly knowlegeable people refer to "Mobile 3309" and to some newer, apparently semisynthetic, ATF by Mobile which may be better than 3309. However, so far I haven't been able to find any other reference to this other Mobile ATF. Maybe it is still called 3309 but either the formula has been tweaked or 3309 has been further tested so that it's advertised applications have increased.   According to this site Mobile 3309 can be used in Volvo transmissions: http://store.avlube.com/mobilatf3309.html.   By the way the 5-spd auto tranny in my 2004 V70 2.4L non-turbo is made by Aisin of Japan, and I believe that yours is an Aisin too. Aisin may also make trannys for Toyota, hence the question by some whether a certain Toyota ATF will work in the Volvo. The answer is not clear to me. But it does appear that Mobile 3309 will work in the Aisin trannys in our Volvos.

Replying to: sheraotwp (Feb 18, 2009 10:22 pm) This should all really go into the transmission forum, but I'm just going to finish my reply here. Note that reportedly the Volvo ATF is fully synthetic which means it should last longer than a non-synthetic or even a semi-synthetic. (This is if one can rely on the reports of phone calls to Volvo.)   This from another discussion on Swedespeed Forums:   "The Volvo fluid is JWS 3309. Check the latest technet note 40-04 about fluids for transmissions and AWD Volvos. Heres the copy for it:   NO: 40-04 DATE: 10-13-2005 MODEL/YEAR: All Models SUBJECT: Transmission and AWD Lubricants REFERENCE: Owners Manual and VIDA Application Note Part Number • 5 and 6 Speed Automatic Transmissions -AW55 -TF80-SC This fluid is also recommended to address two complaints on the AW 50-42: •Harsh Lock-Up engagement/disengagement (SB 43-0029) •Squeaking noise during low speed turns (TNN 43-11) JWS 3309 The only oil approved for the 5 and 6 speed automatic transmissions is JWS 3309. None of the other fluids available on the market have been evaluated by Volvo to meet the requirements of these specific transmissions regarding: • Shift quality • Slipping lock-up functionality • Transmission durability 1161540 (1 liter) 1161640 (4 liter)   Reply from another poster   I see what you've posted...even if it and the Mobil-1 both are JWS3309, one is synthetic (Volvo's...as confirmed by them to me) and Mobil-1's isn't (confirmed by Mobil Oil Co. to me). You can use either, I know...but if it were me, I would rather stay with the more expensive synthetic ATF.   But other posters state that the newest version of Mobile 3309 are in fact synthetic. So in my car I would use the latest version of Mobile 3309 if it indicated on the label that it met the Aisin specification of JWS3309. Replies to this message: fedlawman (Feb 19, 2009 4:45 pm)

#77 of 79 CEL-Low CatCon Efficiency by curtcharlespdx Apr 11, 2009 (2:38 pm)
2000 V70R, 56K miles. Runs super. Check Engine Light (CEL) is mostly on, occasionally off. OBD II reads "Low Catalytic Converter Efficiency". We replaced the CatCon (with a cut-rate aftermarket) but CEL was still on/off as before. Re-installed the original equipment CatCon.   Suggestions on what to try next? O2 sensor? Front or rear one? Other?

#79 of 79 Valve Cover Gaskets by mk2rock Oct 07, 2009 (7:34 am)
Good day,   I have a 2000 XCV70 that is leaking oil.   local mechanic put a dye at the last oil change, and is now indicating that the valve cover gaskets are leaking.   I read some where that these models do not have gaskets but a special sealant, and this is a major undertaking.   Is this correct? Or are there in fact gaskets that can be easily repalced,,,   Any help is appreciated
