Instead, if you're having a garage do it, get them to do a "sump-dump" change - drain the contents of the gearbox sump, refit the drain plug and then top up with fresh fluid to the correct level.
Repeat at monthly intervals until the fluid stays clean. Usually 3-4 of these -art-changes does it.
You'll have the AW30/40 or 30/43 box in it, if it's the 40 the stall speed is 2700rpm and if it's the 43, stall speed is 2100rpm. Out of all the boxes fitted to the 7/9xx cars (and the V70 is a development of them) most are about 2100rpm stall speed - pg 101 shows this on this pdf :

Oddly couldn't find a listing for the B6304S, i know they ade one so maybe i need to find another Data Pocket that lists it.
I've just typed all this and realised you said V70 - that's the FWD jobby isn't it?
I'll try to find more specific data on the box you're likely to have and data on it. The sump-dump advice still stands though. |
What sort of mileage does the box oil need to be changed at if it's never been changed before?
I've been told that the box has got a paper type filter in it. Surely that'll be close to breaking down by now?
In fairness I don't think the garage is going to flush it but they'll be removing the sumo to change the filter then replacing the oil.
They're an auto box specialist and they've not mentioned anything about potential problems or anything?
Cheers
