B4 Servo replacement for '01 XC
Just wanted to say that if the serial # on your Aisen Warner falls within the range quoted on the forum, by all means get the kit (under $25.!) and have it
installed (about $80.) Generally the range includes XC 70s manufactured between March '01 and July '02.
I had serious shift harshness/rpm flare from 2nd to 3rd, and this install fixed the problem completely. Not only that, it provided a much smoother downshift from 3rd to 2nd.
This is my first post to the forum, and it appears this fix saved me $4K!!!
I have also heard from a number of Volvo mechanics that a power flush for high mileage transmissions IS dangerous because it can dislodge sludge that could then clog the valve body. A better fix is frequent service which allows for half the trans fluid to be drained and replaced, with the addition of a half pint of Seafoam Transtune. This hopefully will clean the valve body over time with less danger of a clog forming.

V70 Transmission cooling line filter
I want to install the magnetic micro inline filter like Folkster did. Does any one happen to know the inside diameter of the hose I have to cut is? I think it's ether 5/16 or 3/8. Would like to have the filter ready ti install so if I knew what the hose diameter is I could order it now. Great site, have leaned a lot from you all.
Safer way to drain and fill and use of scale to change oil
Hi,
I did the oil on my 2001 with 125K last night.
I been reading the forum on various ways to change the oil and I was concerned over all the disasters described and the sensitivity of the fill volume and the significant thermal expansion of the ATF fluid. To address that I did it little different. I purchased new o-rings and a new clip for the cooler connection and when I changed them I measured all the dimensions of the fitting and made a copy of it that I put a 1/2" hose barb on. I re-used the old rings and the clip for it.This allowed me to get a 100% secure hose connection. I also got a hose that slipped nicely over the oil return fitting that I connected to a funnel for filling the new fluid into the tranny.
(I was intending to fill through the dip stick and made a "dipstick lookaliker" with a hose barb on but it appeared easier to fill through the return line.)
To change the oil I put a gallon bottle on a Sams club remote readout shipping scale that allowed me to measure the weight of the oil I pumped out while sitting in the car. I then weighted and marked the Toyota oil bottles (nom 870g total, 800g oil). Using the shipping scale I took out about 1600g oil at the time and filled back two quarts. After I was almost through my 12 qt I did a careful tally on all the container weights using a more precise 5g resolution kitchen scale allowing me to fill the oil back within +-20 grams. A full gallon bottle is only about 3000g so you don't need a big scale. Make sure you weigh and mark all containers (including the fresh oil ones) before starting.
I also measured the dry weight on my rag so I could account for the oil spill I got when disconnecting the hose from the cooler.
This is probably nothing new but it is worth repeating since it makes it much easier and less risky. It is quite hard to measure three gallon very precisely and the dip stick sensitivity and the oil expansion issue makes it tricky to know how much oil to add back in when filling. Using the mass of the fluid eliminates most errors and it allow you to know exactly how much oil you took out and putting back in including minor spills. (Just weight the rag after you collected the spilled oil on it.)
the Harbor freight 5000g $19 scale is probably perfectly fine for this.
Here are the fittings I made, the second one is for the dipstick tube but I have not needed it yet since I filled through the return hose.
