Trans flush machine

[PowerDubs]

Anyone have any experience with these?

One of my cars has a W12 engine. The trans is 'sealed', no dipstick.

The service procedure is drain, then fill through a hole while monitoring the temperature via a computer hooked to the OBD port. It is a PITA.

The service interval is every 20k.

I'm considering picking this up so I can swap fluid without the hassle of the drain and level procedure.

You still need to check and set the level after any fluid exchange. I have done them with a machine and found some to be low when done. w12's rock. Mike

As long as you measure how much you took out I see no big deal putting the same amount back in through the filler hole.

We use the BG version. The rep says it only puts in what it takes out. Seems to be pretty accurate so far.

I'm going to guess your W12 engine is in a German car... perhaps it's a Phaeton or Audi?

That machine works with quarts, not liters. Something to consider... I have no experience with any other transmission besides Mercedes transmissions. Slightly less or slightly more fluid into an MB transmission and you'll have a problem. Something to consider... although that machine is cool.

Just curious... why the 20k interval?

we've got a BG machine also. PF5 maybe? it works well.

i work at an independent trans shop, we use a "Hot Flush" machine. it seems to do the job well, can't think of the name, just reads "hot flush". Seems it is a tad low each time we use it, have to add about 1 qt after each use to each vehicle.

I'm really curious, what do you have that has that engine in it? SUV, sports car?

I have been using the bg pf5 machine for years without a problem.

But u need to always check the level after u are done
And a lot of the new German cars need to be warmed up to certain temp from the transmission before it will be the proper level

As u will always loose fluid disconnecting the lines and be careful mixing any atf fluids with cvt transmissions we have a separate machine for those

I use the BG now, works well. Have used the wynns and snap on in the past. Been over 10 years since I used a snap on do not even see one on the sight any more no issues I remember with it.

I have a 2006 Phaeton W12 4-Seater (444hp), my FIL has a 2005 Phaeton W12 5-seater (420hp) and I also have a 2005 Phaeton V8 4-seater (335hp) that requires trans fluid services.

VW lowered the mileage on the W12 to a 20k interval. I'd guess it is the heavy weight of the cars that is cause.

did you see that in print? or dealer recommended? Mike

it also has to do with the fact they can't seem to make a solid automatic that isnt a maintenance pig.

The DSG trans is 40k intervals, I could see the w12 being 20k.

They are a pain to do, but what is your dealer charging? My local Audi dealer only charges 400 to do the trans service on a DSG. The fluid and filter isnt too much less than that. Maybe something to check into.

Plus these newer automatics use special fluid such as Mercon V in Fords,ATF+4 in Chrysler products and Honda fluid in Hondas.The machine does more damage than good,all it does is push all of the dirt and crud around from the inside of the lines.Honda does not recomend any type of flush fearing transmission damage.Plus I have replaced a transmission in a 1999 Monte Carlo once,customer had it flushed some where else and never worked right after the flush was done.Fixed it once and problem came back ending up replacing the transmission.

To be fair, they have the trans pushing a car that weighs 5300+ pounds, has 444hp / 413ft lb, yet shifts utterly seamlessly and quietly.

Throw a couple passengers in the car and it might as well be a truck towing something.

Well, if you are just doing fresh fluid, not a flush cleaning product, I can't see anything getting stirred up or loosened. It is just old dirty fluid out, new fluid in.

Why would there be dirt inside a transmission?

And rmc115 is right. You still need to check the fluid level when you are done.

Go visit Z transmission in Muskegon,Mi,they make money off of flushes called valve body cleanings.The dirt and crud get dumped in the valve body,this transmission repair shop sees this a lot and the valve body cleaning is more than the flush.I know the owner very well including his son.My father was down there once seeing a valve body full of dirt and crud,customer had the transmission flushed.That valve body had to be completely taken apart and cleaned out good finally reassembled.Transmission did not work right at all after the flush was done.My father's shop,tell the customer no on the transmission flush since it is not done here after they ask to have it done.Basically drop the pan changing the fluid and filter pouring in the recomended ATF what it calls for.

I'm still not seeing your correlation of changing trans fluid with a flush machine via transmission cooler lines = transmission problems, but changing transmission fluid by dropping the pan = no transmission problems.

 

[wafrederick]

All of that dirt crud from the lines get disturbed getting loosened up and dumped in the valve body.Plus if you don't use the recomended fluid,transmission damage will happen.A plugged up transmission filter will cause shifting and performance problems.Had this with a 1992 Dodge W250 4x4,the customer said it was not shifting right and the performance was not there.The filter was plugged up,he never had the fluid and filter changed until 350,000 miles for the first time.Fixed the problem with the shifting and performance problems.

Is Motul on the spec sheet? I recall seeing a VW formula... Try that, get it analyzed to see how much longer you can run it. I'd go nuts with a 20k interval.

I've heard of this... But have never seen it.

My BG machine just exchanges fluid, It does not use some sort of super pressure to create all this dirt in the lines you speak of in fact it uses the trans pump itself to move the fluid, it just lets the old stuff out and new in under normal pressure no added dirt that wouldn't be moving with out flushing it. It's not black magic or evil transmission damaging practice. I am a trans tech and nothing wrong with the flush machines I have seen.

Now on the other hand I have seen people most likely unknowingly and unintentionally crack a filter when replacing it causing strange problems. Or the pan will leak after the service, etc. definitely room for error there.

Try to find a shop that has gone out of business you can buy equip for pennies on the he dollar.
