How many miles do you have on your original AW55-50SN transmission?

HOW MANY MILES DO YOU HAVE ON YOUR ORIGINAL AW55-50SN TRANSMISSION?

Just wondering...

I bought a 2006 Volvo S60 with 191,000 miles on it. Does ANYONE have an 06 with that many miles on it that has a transmission that still works properly?

It drove great during 3 test drives. The guy we bought it from was driving it as his daily driver so it was always warm when we drove it.

Once we got it home and drove it for the first time in the MORNING, when it was COLD (like 20 deg F) it "hiccuped"
between 2nd and 3rd for the first few takeoffs (going from 0 - 25 mph in city). It has done so ever since (2 months). It sort of "lurches" when it shifts between 2 and 3 the first few 0-25 accelerations - it does not really SLIP - the rpms dont go up when it is shifting - they stay at say 2000RPM, it decides it going to shift, it lurches rpms stay at 2000 rpm then it finally (after like 1/2 a second) goes into 3rd. It does not "BANG" or anything.

Once it warms up after a block or two it is FINE for the rest of the day / evening. If I let the engine warm up first thing in the morning for say 5 minutes, it does NOT do it.

So, it has something to do with transmission fluid temperature.

Should I get rid of the car (make the seller buy it back) over this, or should I try replacing the fluid and then getting the software update. Car has a bad "t-bone" top engine mount too. That probably contributes. I had a new B4 Servo cover put on - made no difference in 2-3. Have not done fluid change or software yet.

There is a VOLVO software update the specifically addresses this issue (2-3 shift when COLD) but NOBODY can tell me about it / if it works / how much it would cost, etc, etc, etc - it is very frustrating.

I just want the thing to work for another 100,000 miles - it is like new except for this.

Mine has 200k on it and still works well. Sometimes takes slightly longer to do some shifts when freezing outside before the oil is warm. But that's it.

I have 230k miles on the original transmission. I've done the flush and installed the Magnafine filter and oil cooler. And have done the B4 washer replacement.

Excuse my ignorance..... If that's what we have in our 03 V70 NA and 05 S80 2.5T, then we have 235,000 and 195,000 miles respectively and they both still work fine. But we don't abuse them and we do complete flushes every ~30,000 with Mobil 3309.

I will add my own ignorance too: I have almost 184kMi, did first fluid change ever and the B4 servo cover around 76k, then removed the famous 'neutral stop'. Drain/fill (sounds like overkill but I still do it) at every other engine oil change. Without any modifications still working fine; planning on rebuilding the valve body this summer if I decide to keep her for another couple years.
Very important: baby it = NO ABUSE (the keyword should be one word). My son tried to make me race her but no thanks

To the OP: I would check with the VIN at a stealership for the TCM S/W version and history; then change the fluid for good measure before deciding on anything.

THANK YOU ALL - makes me feel a bit better. It really does drive like a dream once it warms up which takes just a few minites. I look up "stuff" and end up reading lots of scary posts.

I call the "stealership" and they won't tell me anything. They claim they can't tell me what version of the software is in the car. They want like $150 to install and transmission software and they want to DIAGNOSE (read CHARGE $$$) what is wrong with it first.

If I buy a VDA thing does it SERIOUSLY only run on Win XP? Will I be able to get and install updates?

Thanks

I agree with Regents comment.
My V40 did what you are describing but only when cold. The transmission fluid was quite dirty looking at the time also.
I did 2 drain and fills with synthetic 3309 and no problems since.

- I agree with ATF flush. Make sure you use the correct fluid as mentioned. Search rmeuropean or eeuroparts, they carry Aisin fluid.

- On a related note, my 1998 S70 GLT AT with 187K miles just lost REVERSE, all forward gears are OK.

- I have a rule of thumb...I only buy car with 100K or so. By the time you buy a car with 190K-200K miles, the trans lifespan is up there and can go any time. Not a cheap fix!

My fixed costs for my airport runner are down to $300 per year for insurance plus registration.

That’s a pretty flat depreciation curve!
