I posted this message on the XC site a few days ago and did not get much response, so perhaps there are some viewers on the V70 site that can help.
I took delivery of a '98 XC just two weeks ago, already have 2,000 miles on it. There seems to be a noise, like a gear slippage, when the torgue coverter locks and unlocks and it happens every time. There are no other problems with shifting. Any ideas??
I did have a suggestion to change the trans fluid and I am running down TSB 4430029 which addresses the fluid change issue.
BTW, I e-mailed the dealer and they don't seem to think the problem is serious, but it sure is annoying. They promised to look at it at the next service. (But we anal people must search for a solution.) I have had a great experience with the dealer so far - Paul's Motors, Hawthorne, NJ - The purchase experience was great thanks to Chris Corrigan, in sales, and on the second day of ownership the ABS module went out, they took me right away, replaced the module, found the rear washer motor was also bad and replaced that, gave me a spare headlight bulb, just in case - all with a smile - go there!

Hi Ray,
Burned transmission fluid may be your problem. I had a simular problem last fall.
Volvo has stated to me (I had a "Long" talk with two factor reps and an actual Engineer from Sweden and in a service bulletin (http://www.nhtsa.dot.gov/, look under problem & Issues Bulletin Number 4430029) ) that the transmission fluid can be burned (i.e. worn out, no longer has the quality of a hydraulic fluid). When this occurs your toque converter lock up no longer works as designed. This is best notice when you are driving between speeds of 50mph and 80mph(in my case 55mph is the best speed to notice the problem). You will notice a shutter every time you put your foot on the gas. It is like running over a row of small rocks. This problem can be fixed easily by flushing the transmission fluid. Volvo told me that there is no long-term damage done to the Transmission if any damage was done at all.

Steven,
Thanks for your reply. You have described the problem EXACTLY as I have experienced it. I ordered the Service Bulletin from the Volvo Bookstore last night - a great service - and downloaded the bulletin this morning - It is interesting that in order to properly flush the trans one must remove (actually, have the ideling trans pump out) 2 quarts of oil, then add two new quarts of oil, then repeat the process 7 times until the oil is red - as in new oil. I sure hope this will be covered under the warranty, and I expect it will be because there is a mention of that in the Service Bulletin.
I got several bulletins from the Bookstore, including one that explains the tire wear issue (#4 46 0005 dated 01/01)- with all the appropriate warnings about same tire all around etc. that has been well discussed on this Board. The Bulletin's are copy writed so I will not post the full content but I don't think they would mind if I quote part of it...."Caution! Failure to always drive on properly inflated, identical tires of correct dimensions may result in a circumference difference between tires on the front and rear axles. This will cause excessive tire wear and may damage the transmission and all wheel drive system." This does not sound like just someone's opinion, so fore warned is fore armed!
Now if I had the opportunity to spend time with some folks from Sweeden I would ask why such little difference in tire circumference can cause so much mechanical damage in such a short time....and, BTW, how much difference is too much.
Thanks again for the reply.
Ray

Ray-
As far as rolling circumference, the UNOFFICIAL tolerance is 1%!!! That equates to approximately 8/10 of an inch- the standard tire on the XC (205/65-15) is roughly 80 inches in diameter. A new ContiTouring Contact versus one with half the tread worn off EXCEEDS this tolerance. Keep those tires rotated!!

Hi Ray,
Another note on the burned transmission fluid. You most likely found some responses stating that Volvo used bad fluid and hence the required flushing. This fixes the toque converter lock up at hi-way speeds problem. I had the same problem last summer with my 99 V70 XC. The Dealer did a complete flush of the transmission at 16K miles. However at 21k miles (around December) I had the problem reoccur. The toque converter would not lock up correctly at high way speeds. And to my surprise the fluid was burned again. I have own nothing but cars with automatics and non of them has ever had burned transmission fluid at such low mileage.
This time I did not go back to Volvo or the Dealer. I beg my BMW mechanic (he only works on BMW) to look at the problem. His recommendation was to add an external oil cooler and a paper filter. He felt the transmission was running too hot thus burning the fluid. He also noted that there was no paper filter on this transmission design (there is a wire mesh that is not easily accessible). He felt that metal particles from the break in period should be filtered out of the oil. I had him install both items in late December. Now I have 26K and the transmission fluid looks great.
I consider the problem solved.

Steven,
No one has yet to say that it was bad fluid, but I guess you did. Interesting though, that the problem recurred so soon. I do recall reading in the owner's manual about all transmissions having an oil cooler, but I don't know if it was internal or external. This was an important point to me because I will be towing a boat (about 2500lbs with trailer, fuel and normal equipment on board.) I won't be towing any distance, just around my vacation home on a lake in Maine. None-the-less, this is an important issue and I will look into it. By the way, great job you did in solving the problem. Thanks for your reply.

Hi Ray,
I was told by the Factory Rep/Dealer that the Factory used fluid that was defective. However, I have read on this Bulletin Board and others where owners are changing Transmission Fluid as often as their Engine Oil (around 10K). I have also talked to a local Volvo Mechanic and he said that this is normal for 70 series automatic transmissions.
My issue is what is causing the Fluid to go bad? There is nothing in a transmission that can contaminate the fluid like there is in an Engine. The only other idea that I came up with is Heat. Therefore, I install an after market transmission oil cooler. Also note that the transmission oil cooler in the V70 XC is part of the engine radiator. I install my after market oil cooler in series the oil cooler that was already in the car.
I would recommend that if you do some towing to install one. Mine fit just fine in the lower drive side of the radiator (in the front of the radiator). If you like I can e-mail you a photo of the installation (I have no way of posting it to a web URL).

Steven,
I think you hit the nail on the head with the oil cooler, I don't need a photo, I think I can visualize it well enough. Of course the real pregnant chad here is, as you so well asked, Why? Why doe the oil continue to burn. I will have a chat with my dealer to see what I can find out.

Hi Ray,
Good luck with the Dealer. I got no where with the Dealer. I also had a talk with 2 Factory Reps and they said that this was normal! I say bunk! All of my cars I have own have had automatic transmissions and not one of them has ever burned the transmission fluid not even when I have passed 100K miles.
If you decide to install an oil cooler and would like a photo walk through let me know. The offer for a Photo walk through is still open.

THis is amazing, I am so glad I found you guys! I just posted on the wearing out of tires(2) and being told all 4 must be replaced together always! But I began complaining about a stutter between 55 and 65 during a long drive about 2 months after we bought the car (99) and no one would believe me. I am now at 27,000 miles and I am still complaining about this "stutter". I made the dealer service manager ride in the car with me and he said it was normal and that what I was feeling was the automatic shifting, it was sort of "deciding" what gear to be in. I have owned Volvos all my life and have never had one "decide" in this manner. I hate it and it makes long drives irritating to say the least! I am printing out your comments and handing them to the dealer today as my car is in for it's 30,000 mile service and I will show him I am not imagining this! So now I have to look for a discussion on the driver's seat rocking-makes acceleration a thrill yet I prefer my rocking chair on the front porch.

FOr the driver's seat. Talk to dealer about Tech bulletin and installing shock piston on seat rails.

The dealer is ordering the part for me, thanks for the information. It sure helps to walk up to the service counter with a printout of the information gathered on this site!

Welcome aboard! I'm new here too, and the torque converter issue was my first posting - boy did I learn a lot. I did know that the root of the trouble was the locking and unlocking of the torque converter, I just did not know why the shudder. If you check your owner's manual you will see a reference to the torgue converter locking and feeling like a shift, when it unlocks it feels like a down shift - that's all normal - the shutter is not and it is annoying as hell. Tell your dealer to check Service Bulletin #4430029 dated May 2000. It not only spells out the problem, the fix (hopefully) but also that it is a warranty item as long as there is a documented customer complaint.
There is also a Service Bulletin (#4460005 Dated Jan 01)which discusses the tire issue for AWD's. The most important part is to know that all tires must be the same brand, model, size,approximate wear AND all properly inflated. Severe excess tire wear and mechanical damage to the transmission and all wheel drive system may result if this caution is not heeded.
Go figure.
Ray

Thanks for the info, they did the transmission fluid flush (and did it on warranty), the stuttering is gone, for now, do I need to worry about it returning, and if so, then what do I do?

I flush mine ever 20-30K miles, and the problem has never re-occurred.
