They might recommend one of the high spec Fuchs oil.....

They might recommend one of the high spec Fuchs oil.....

I understand that Fuchs is what manufacturers in Germany use for factory oil... should be real good stuff then.

[Markjay]

Get in touch with the guys here:

www.opieoils.co.uk

Very good and can offer advice, might even be able to get the Mobil stuff you are after....

'Thanks for the mail.
 
We do not stock the Mobil ATF I am afraid.

Our alternatives are from Motul, Amsoil and Fuchs.

Opie Oils'

You were right... will ask them for details. Thanks.

It might be worth while asking if they mix with Dexron III since it's impossible to get all of it out.

It might be worth while asking if they mix with Dexron III since it's impossible to get all of it out.

I asked  before - apparently all synthetic ATFs mix with mineral ones. But - I read somewhere that the total capacity of the ATF is actually 9L, and that the specified drain capacity of 4.4L is because the rest remains in the torque coverter -  - can anyone confirm this?

If this is correct then it may be pointless to use ATF at all, would seem to make more sense to use standard ATF and then change it a couple more times to flush-out the old one based on the idea that it is better to have 100% new standard ATf then 50% synthetic and 50% old ATF....

I would some ATF MJ, gearbox might not like it otherwise

Nitpicking!

AMSOIL's website describes a method of replacing the ATF in the torque converter, basically what they say is disconnect the lines to the transmission oil cooler, start the engine, and have an assistant fill-up the transmission with fresh ATF through the sump filler hole while you are watching the ATF coming out of the pipe. When the ATF coming out is clear (a bit like brake flood replacing...), or when the known full transmission ATF capacity has been added to the sump, stop and re-connect the oil cooler pipes. This is doen AFTER replacing the ATF in the sump in the usual way. Anyone ever done this before?

OK, here's what it will cost to get the job done properly:

Autobox gasket set - £13 (Vx Trade)
Filter - £60 (Vx Trade)
   either
10 x 1L Vx Dexron-III ATF @ £7 each = £70 (Vx Trade)
   or
11 x .9L AMSOIL Synthetic ATF @ £12 each = £132 (Opie Oils)

Total: £143 for Vx ATF, or £205 for AMSOIL

Blyme....

What about the Fuchs Titan ATF 4000 (24 quid a gallon).

Use a loctite flange sealent instead of a gasket (less likely to leak and cheaper)

I clean the filters in parrafin (they are a foam gause so it works quite well)

Thanks, see my comments below:

- Sounds good, that's around £60 for 10L - haven’t heard back from Opie Oils regarding alternatives to the Mobil I initially asked about

- as I already bought the gaskets the expense has been made whether I end up using them or not...  

I clean the filters in parrafin (they are a foam gause so it works quite well)

- will do.. I was concerned it might be felt, bit if foam should be OK!



What about the issue with emptying the torque converter by disconnecting the oil cooler pipes – any advice on that?

[Marks DTM Calib]

Its a method that I have thought about, but never tried.....there is a line that can be got at on the drivers side chassis rail under the bonnet..

Well if I go for synthetic ATF, then I'll also have a go at emptying the torque converter and oil cooler as it makes sense to have the entire 10L changed (or as much of it as possible). If I go for standard Vx ATF I may not bother - and just let the old fluid mix with the new. Let's see what Opie Oils have to ofer....

I'm sure I've seen one of these pipes under the car with a rubber bit of hose near or in front of the gearbox. Presumably the pipe from the back of the box is the outlet from the pump. If the rubber bit is disconnected from the back bit of metal output tube and popped into a bottle of fluid and the breather hose is blocked up temporarily will it suck fresh oil in, take it through the oil cooler, torque converter and back into the gear box that way as it pumps the old out? I don't think I'll try it since I'm sure the seals aren't designed to withstand a partial vacuum in the box...

Thinking about it isn't it going to be pumped through the cooler and then the torque converter under pressure, it's got to be under pressure to go into the torque converter otherwise it's not going to fill it - does that sound right?
That also means that it's not going to change any oil in it with the cooler pipe disconnected though - I think.

I had a carbon vane liquids pump at one time and I bet I could have used that to pump fresh oil through the cooler and into the torque converter. Do those power drill pumps manage to generate any pressure to do this?

The last idea (I promise) is to extend the oil pick up, whilst the sumps and filter are off, into a bottle of fresh oil but that's assuming there is some sort of pick up tube.
