Questions on 2001 transmission failure (planning ahead!)

[xHeart]

The English translation would be like this, do not D&F if last 6 digits of VIN# is less that 067100, and higher than 036000. Yes?

[fazool]

Well, I'm not sure about D&F advice in particular, but one common design flaw was a washer breaking loose under the B4 solenoid. Apparently this is limited to that range of cars, meaning if your VIN is lower or higher than that range, you will not need to do the B4 solenoid cover fix.

If you are within that range and have tranny troubles, that is a quick cheap fix and should be an early effort in repairing it.

I think

It is a fix for CERTAIN troubles only (like those related with 2-3 shifr flare). There are quite a few other 'bugs' that the B4 Servo Cover Update by itself won't cure, and it is great that you do not have any of those.

I am glad to hear about another flawless Aisin 5-speed transmission in existence (like mine '02)

By all means stay away from a power flush machine but if your fluid looks ok now, I would start on a replacement cycle. Tranny fluid has a finite life despite what manufacturers would want you to believe. Some of you speak about your transmissions as if they are sentient beings just waiting to stick a knife in your back if you screw with their nice dirty fluid. Never seen evidence of this myself. I have flushed an AW30-40 that has never been touched in 410,000km and I can tell you she really appreciated it!

A follow up to Fazool's post, within the chassis range, the first 3 digits of the serial number on the affected transmissions are between 01C (March 2001) and 01L (December 2001).

IPD suggests a software update (regent noted above) before replacing the B4 Servo Cover. Does this replacement remedy the design flaw you point to Fazool?

DYI Flush

Machine Flush


If the transmission is not having any problems then the first thing to look at is the color and smell. If the color and smell is OK then the transmission is a candidate for the DYI or Machine Flush that uses the cars pressure to circulate fluid. There are perhaps machines that use added pressure for flushes but it may not be likely as it is obvious to a Manufacturer that added pressure can move potentially very dirty debris in a badly worn transmission and circulating it causing more problems. Assuming both method above only use the vehicle's own pressure either should be fine.

Transmission fluid is high in detergent and like kerosene and diesel has been used as a flush though not close to the effectiveness of the later two. I have seen diesel used as a flush and heard of transmission fluid as hand cleaner by old timers.
Discussion Title: Transmission Fluid to flush an engine
http://www.askautoinfo.com/discuss/clus ... age_1.html

With that said if your fluid is fairly clean you know your transmission is not wearing a flush should be OK.

I was asked by a friend to do this work last week. He was getting codes and was not able to permanently clear them. Even when the code was cleared the OBDII still did not have all green but the yellow light flashed. This is all to say that even though his fluid was pretty clean there was a build up over time (174,000 miles) and the Dealer and Transmission shops only remedy was to rebuild. He found the link below and now it is good as new so I think if you drain and fill and there is nothing on the magnet you should replace the fluids.

Swepco's 714 Transmission Oil can be used as a substitute for engine oil and the forum above in the discussion verifies that although it needs no verification. If you put the 714 in your Volvo you can go 100,000 miles though I would look at it to see the color and smell as transmissions do fail. Brought a barely driving 88 Mazda back to life. Fix a slipping 88 Camry with 258K miles to normal driving condition and a 1995 Plymouth Caravan never gave a hiccup with it. Read the attachment on temperature drop/difference by the Tranny builder. You should be able to buy it directly but I get it from the local rep. When I was in Food Manufacturing the Stain Steel Manufacturers use to use there oil for drilling stainless for reduced bit wear and ease of cutting.

We've all heard of Swepco Gear Oils, they've been standard issue for Porsche since the 935 was raced. So why should you consider Swepco Motor oil? Zinc and Phosphorous are important anti-wear additives that have been drastically reduced by many of the newer SM oil formulations. These additives are crucial to the air cooled Porsche and beneficial to any car....water or air cooled. Swepco's 306 has high levels of Zinc and Phosphorus as well as including over 5 times the amount of the anti-wear additive Boron as the new reformulated SM or CJ-4 oils.

Contains DIMONYL
High VI solvent extracted paraffinic base stocks
Exceeds major engine manufacturers recommendations
Contains detergent/dispersants

We have a 2000 V70 with a 5 speed AW55-50SN transmission that was built in 2000 ( I think it was July) . The B4 servo cover was bent and we had the 2-3 shift flare problem.

We had the software update done then had the cover replaced. The trans is not perfect but seems to be adapting after a battery cable pull.

BTW I would NOT be placing a Swepco trans oil anywhere near the AW55-50. It is not JS-3309 (or Toyota IV) specced.
It may be OK to use this in the AW50-42 which uses Dex III compatible oil.

[regent]

+1 on the trasnmission oil for the 5-speed AW55-50SN.
It does need to be 3309 period.

As for the adaptives, battery disconnect/re-connect will only clear a limited range of values around the network; however, it will NOT put the TCM in adaptation mode.

Following the replacement of mechanical components (and fluid) the TCM will need "to know" what you just did in order to adjust the system's behavior to the 'new' environment. This is done with VIDA DiCE (you will need to reset the fluid counter, clear the adaptives, and place the TCM into Adaptation Mode; and only then you can perform the 'TCM Adaptation Procedure'). Having the latest TCM software is a pre-requisite (the earlier versions did not allow complete access to some features)

Multi-Vehicle or Multi-Service is OK to use.

Although they do not have the "Meet" they do exceed. Called my local rep who with his dad have sold Swepco for 35 plus years for a living and he did not bat an eye on using it in any Volvo's with the JS-3309 (or Toyota IV) spec. I will also update after speaking with a Local Volvo guy who uses a large variety of Swepco products.

I buy the Engine and Trans oil by the case but now I can get one or two-see's of the other stuff from Independent.

Found this floating on the web tonight doing some more research. Just interesting reading and no I do not sell it.

[xHeart]

Reading through MVS posts, this thread in particular - more of a triangulation.
I am in the chassis range that Fazool indicates. Therefore, planning to keep the "sleeping dog lie".

Is anyone out there with all three procedures done, in what order?
1- Drain and Fill
2- B4 Servo Cover replacement
3- TCM (Software update?)
