bullittandy Posted March 4, 2007 Report Share Posted March 4, 2007 I posted elsewhere but I want a new topic devoted to the idea of a tranny cooler on the V70 auto's that have the shift flare problem. I've done the fluid swap (3 times), software upgrade and B4 servo. My 01 V70 started this shift problem at 100K. my car only does this after 30 minutes of city (slow speed) driving. I had a commute of 75 miles and it never exhibited the problem then, only 30 minutes of stoplighht to stoplight driving which leads me to believe that its tranny temperature related. The dealer offered a new transmission but it ONLY does it after driving in the city and it's NOT getting worse which makes me think it is not a mechanical failure.Do others concur?Has anybody added an aftermarket cooler?Is there are sensor that is related to tranny temp that could go bad?

The reason i used this is because its locally available (any Toyota dealer) and a bit cheaper than others ($4 -quart). Link to comment Share on other sites More sharing options...
Guest 850T-5 Posted March 6, 2007 Report Share Posted March 6, 2007 What, Mercon then Mazda/Toyota fluid? ONLY use VOLVO Fluid or the equivilant Mobil1 spec fluid. Don't risk using other fluids, no wonder you're having problems. After completely flushing it and using ONLY the correct fluid specified by Volvo, pull the negative battery terminal, turn on an interior light and leave for about 10 minutes to completely clear all power. The tranny will need to relearn adaptives with the correct fluid, which will probably help take things back to normal. Link to comment Share on other sites More sharing options...

These problems started before ANYTHING was done to the tranny. I'm assuming that you've read the dozens of posts about the shift flare problems in these transmissions? Valvoline's website and tech line stated that Mercon V could be used in the A/W tranny. However, they were wrong. No big loss, I got them to send me a case of synthetic oil for free and I've provided valuable information to all V70 owners looking to replace their tranny fluid. Toyota T-IV is the exact same fluid as Volvo's according to a Mazda TSB. I'm assuming that you've read that also-right?Also, do you have any info on adding a tranny cooler?

Guest 850T-5 Posted March 7, 2007 Report Share Posted March 7, 2007 Well, you should have made that clear then before showcasing that you weren't using the fluid specified by Volvo for these transmissions otherwise you make yourself a target. You sounded like one of those guys that doesn't know what he's doing and assumes the problem is something else rather than not using the correct fluid. Mercon is completely incorrect and should not be used, which was an indication to me that perhaps you were one of those types of guys. I have not seen anything proving that Mazda transmission fluid is the exact same as the Volvo/Mobil spec fluid that is required for these transmissions either, and additionally as said above, why risk it? If the vehicle didn't come from the factory with a transmission cooler, it is not necessary for it to function correctly unless the transmission is going south or there is something else going on as mentioned below. If the transmission is in good shape, you are using the correct fluid and it is clean, you've checked with the dealer to see if there are any transmission (TCM) software updates and had them performed, and after changing out the fluid with the correct fluid, you reset adaptives there shouldn't be any problems.

I don't believe I have ever heard that particular simple idea before as a fix to this issue however I'm slow ;) Link to comment Share on other sites More sharing options...

You're right. But if I were an idiot wouldn't it be better to be nice so I'll listen?2. Not Mercon, Mercon V, newest formulation acording to Valvoline techline, supposed to work.3. I have read the TSB. Why risk it? Because Volvo fluid is too expensive and Mobil fluid has to be ordered-I have a short attention span. AND I read the Mazda TSB.4. This is just flat out wrong, almost all transmissions are killed by heat, factory coolers are not always enough. For example, early 90's Q45's destroy their trans within 70K miles unless you add a cooler then they make it 150K.5. No problems? You need to read the dozens of posts of people who have the exact same problem. Link to comment Share on other sites More sharing options...

Must be to a JWS 3309 oil specificationthe mobil fluid is mobil 3309 available by calling a local dealer and picking it upThe Toyota flluid is the same stuff from MobilFord has that fluid now in motorcraft as well.As long as you have an Aisin Warner 5 speed auto, then the above is correct.People shouldn't call it Mobil 1 because it's not. That's to the Dexron/Mercon specModerator should tag this for future reference Link to comment Share on other sites More sharing options...
