Lubegard and Lucas

[Willow place]

The box is starting to snatch again, it has Lubegard in it ,if I drained 3 litres of fluid out and replaced with Lucas plus the 3 litres or there abouts ,would anyone know if this would Gum up the works ? D5--2003 V70

Depends how long since it was done last. I’d personally do a few repeated drain & fills whilst driving in between to allow the new fluid to mix with the old. Get as much of the old fluid out as you can, until eventually it’ll be a cherry red colour. Simply doing one drain & fill is practically useless… yes, you’ll have fresher fluid, but it needs a few drain & fills to be much cleaner.

The transmission can hold more fluid - 3L approx is the desired level. The transmission can take at least 1L more, so 3L of transmission fluid & some Lubegard shouldn’t be any harm (so long as you don’t put more than 1L in).

What Kev ^^^^^ said but be careful about overfilling as that can cause frothing. Frothing can cause cavitation which would be bad - very bad!

As suggested, a few drain/refills spaced a few hundred miles apart, keep doing them with new fluid until the fluid remains clean for the few hundred miles. Easy way to see if it's clean is to withdraw the dipstick and wipe it on clean white kitchen towel. The correct colour of the fluid will show up as well as any dirt. Should be cherry red (which might look pink on the white kitchen paper) same as the new stuff.

Should have made my post clearer, I have over a period of time changed the old fluid, 20 litres overall was used ,the fluid is perfect now , but having tried the Lubgard which appeared to help the 'box it is snatching and in reverse I have wait about 15 seconds or there is a massive thump, after reading on the Horton cars blog about Lucas additive thought I would try it, I will drain out about 3 litres and replace with same plus the Lucas stuff .

Worth a try. Just don’t overfill it too much.

presumably you mean, replace with the same volume, which includes the lucas stuff

i think this is why you're getting warnings about overfilling

that being said with the lubeguard if you read the instructions (unless I got it wrong somehow) per 3litres, you only put in about 80ml which is not a great deal . I just put that in the measuring jug first, topped up to 1ltr, poured it in, then measured the rest

it wasn't actually 3litres it was more like 2.7 / 2.8 in my case

Interested to hear the after-report if it made significant difference, always useful to know for when I do mine again in a couple of years

Is the transmission control software up to date and were the adaptions and fluid counter reset with Vida or a suitable scan tool?

[Willber]

Is it possible to update the TCM software with a copy of VIDA and DICE? I see that you sell them ready to go on a laptop but unsure if you need to pay for the updated software etc. Cheers!

You technically could but the cost of even a temporary subscription plus the software means that for new software, you may as well pay a dealer.
Some even do updates as a free/included part of a service.

Independent Volvo garages can also do software updates. That’s another option.

As cheshired5 says… adaptions, any software updates & resetting the transmission fluid counter are very important.
