6Spd Auto flush out.

[Ivo]

So as we all no the auto box is sealed for life LOL. I decided to get my oil changed about 6 months ago. It was starting to shudder when changing between 2nd and 3rd. Not always but often enough to know something needed to be done. As you know they can only get about 4lts out when dropping the pan. My oil was black, I had a new filter and gasket fitted and used penrite oil.

There was no change in shifting and the shudder seemed to be getting worse. When I had my water pump replaced last week the workshop said they had a new machine that could flush the entire auto out but it would require a lot of oil. They disconnect the oil lines that go into the cooler/heat exchanger and connect the machine to that. The car is on the hoist with the wheels off the ground. They then start the car and change gears up and down, while the old oil is coming out new oil goes in. The oil coming out starts to change colour and when clean oil is coming out its done. They used 12lts of oil to flush mine.

Only problem was the cooler is made of aluminium and when the hoses were disconnected it tore the threads up. They had to cut new threads to get it back together.

I did not use Penrite oil this time, I used Fuchs 4400 ATF as there is a Fuchs distributor next to the workshop and according to Fuchs, all though not specified this oil will be suitable. The workshop did the same flush with Fuchs on a transporter that was shuddering a few months ago and there has been no problems with it.

I have only just got the van back but have done about 50kms and it has not faltered once. Even on a steep hill that would always cause it to have shudder badly.

I will update this in a few weeks and let you know how its going.

How many km on the auto?

I used a Penrite Dexron 6 equivalent at 75K,but only a partial drain(4 litres).
Data for the Fuchs 4000 suggests it is a Dexron 3 equivalent.

Gee, why I'm not surprised that after the proper transmission flush all the issues are gone?

I know that for many T5er's it's not possible to get oil change in whole driveline, but I say that oil is cheap, the engine or transmission is not. I drain the gear and transmission fluids no later than 20,000km, P/steering fluid every 20,000km in brand new vehicles and the engine oil still at 1,000 - 1,500 km, it doesn't matter that VW is not recommending it. The clean oil can't hurt anything and as long as it is the same oil there is no harm done.
Some may say it's waste of money, not for me. It is cheap insurance, just in case that I need to keep that car for longer than the warranty period.



@Rebuild Penrite no longer recommend any of their fluids for AT in T5 (use VW G 055 025 fluid only - from Penrite site)

Its done 161k.

I need to do this too. I have noticed my auto is "rougher" in its low shifts (1-2-1) and it shudders when reversing up my driveway.

Can anyone recommend a shop in Sydney that can do a complete auto fluid change?

[Red Bicycle]

In Sydney and very interested in this procedure as well - anyone?

Just spoke to my mechanic about this. He said that he could do the same thing and does do it for some vehicles such as Commodores that don't have a drain plug but because there is no dipstick on the T5 he would not do it as he didn't want to take the chance of under or overfill a very expensive auto. However, He says any transmission specialist should be able to do it.

I got mine done at the European Car Center
2/62 The Ave
Maryville NSW 2293

There is a method to get the oil level right, not sure exactly but if they have the workshop manual it should explain how. Its also interesting to note that Penrite no longer recommend an oil.

[Ivo]

I did a google search for VW G 055 025 which is the recommended oil and came up with this from the Fuchs site and it recommends the ATF 4400.

So only having done minimal research into this, I was reading along the way that the transmission fluid change if it has never been done before can actually cause more issues?

Ivo - can you let me know how long and the cost of getting this work done at @ ECC as if I am going to get it done I would rather it be done by somewhere that has done a Multivan before....
