V70 G/box: 2WD: Serious rookie mistake, GB fluid

[Bashy]

Well, all i am going to say is this, i started the GB fluid change, got everything i needed out for that and the oil change and this happened.....

I used engine oil in the gearbox

I was only able to originally drain 2.4L up on the ramps, and i would say about 0.5l came out of the level plug.

about 4.8l of engine oil went in before i realised my blunder.

I have now drained it twice with 2.4l of gb fluid....

On a scale of 1 to 10, how serious and should i put it on the market, quick like?

Had to buy more engine oil so thats costly for a start.

Spending the £250 at the garage to do the flush originally sounds like a good idea , hindsight 'eh?

it takes a great deal to admit your own mistakes, so firstly well done for doing so.
sounds like you have done your best to flush out the wrong oil.
personally I would suggest you now use the car for a while, get all the oil around the transmission system, then do a third change after say 200 miles. then see how the box changes after that, try not to draw many opinions on the gear change currently as still a possibility of mixed oil grades in there.

Thanks stegreg, was most certainly a better reply than i thought i was going to get, i.e. what an idiot, plank, spanner, ratchet and so forth lol appreciate that

I did expect to get more than 2.4l from the box, ive seen others on ramp and pulled out 3L+ so was quite surprised it was so low... Will see how it goes, hopefully i aint wrecked it

for future reference, am i best doing the final level when its on the ground? flat...?

[stegreg]

try to measure what oil you get out, as you did before, so then you replace the same. check the oil level on the dip stick once level on the ground and then let it run for a couple of minutes. leave for 15 mins, then do a re check......then road test and do another level check, say 30 minutes after parking back up.

don't worry, I did a plank job on my 940 once, I followed advise to put 5w/30 engine oil in the engine. it was great when driving, but when stood in traffic, oh boy did the turbo start blowing oil smoke out....flushed the oil and put proper stuff back in.....hey presto no smoke.

39 minutes 'eh?
Thanks for that, i thought level ground would be best to do the level

Worse things have happened.
I think you'll be OK after you dilute the engine oil with correct ATF.

Here's where that 20l keg from Germany (Mannol?) would come in handy.

I'd skip the 200 miles between rinses. You needn't run oil contaminated fluid that long between drains. I'd drive it locally for 25 miles tops. I'd also stop the engine frequently during this operation to let the torque converter drain a bit.

Nowhere has anyone ever alluded to our torque converter's drain down characteristics. By shutting the engine down during the dilution process you're at least giving the TC a chance of draining.

You're not in for a high tech headache. You're in for the tedium of emptying the sump, driving some and refilling it several times.

JUST A THOUGHT: When driving about during this dilution process take note of how your transmission shifts and how it behaves going uphills or how it takes off at green lights.

If you feel slippage don't be surprised. However, don't floor it. Be gentle and stay on schedule. You will get the engine oil out.

How long did you drive between your first 2 GB fluid changes?

Not sure what type atf fluid is recommended for your car.
I would buy 20 L cheap one if JSW3309 is recommended ) from here https://www.smithandallan.com/produc...mission-fluid/
and flushed whole 20l using Gibbons method without driving anywhere and then 20l from
opie using promo code " volvo" for 10 % discount https://www.opieoils.co.uk/p-69402-m...ion-fluid.aspx
Please check in manual what type atf is correct one for you Volvo

I always get 2.9 - 3L when car is of the ground but level but Im using 4 ramps

The way I'm always doing is I put back exactly same amount what I drained from transmission/radiator ( cold engine gibbons method) so I dont have to do final top up.
The best is if you check oil level when oil is hot (80*C)
Engine running, shift through all gears (3sec between) with foot on the brake and after 2 min ( engine still running) check the dipstick with clean paper and top up or drain if you put too much. Bear in mind there is 200ml between min and max

I have never done that but have done things just as silly.

I think as previous posters have said change it as you have. Stick 200 miles on then change again.

I agree with Oragex.

Couple minutes use to mix the fluid then drain. Repeat at least 5 times I think.
Driving 200 miles with small amount of engine oil there is a mistake I feel.

Tbh I dont think that 20L of new ATF is enough to fully flush engine oil from autobox but I may be wrong
