2001 V70 2.4T ATF simple Drain and Fill...

[anilkonda606]

I have same model & make. 2001 v70 XC Automatic Transmission.

Could you please help me with below two questions.

Any specific reason, most of the users are recommending regular Drain and Fill than a complete transmission flush ?

In cold start or hot start, when change the gear from Park > Reverse > Drive, it's a hard shift. However once i am in drive, i never feel any slippage. it drives smooth.

Do you recommend Flush or regular drain and fill ?


Sorry... Third question.

For Drain and Fill - is it okay if follow below procedure, with out ever putting the car on jack stands. I mean i don't have any lifting equipment. So please advise if this procedure is okay ?

1) Disconnect the line that transfers fluid from transmission into the cooler.
2) Attach some tubing to that line and place in some container with capacity markings.
3) Start the engine run through gears and stop the engine, once around 2 qt for fluid is drained into the container.
4) Now pour around 2qt of new fluid using funnel into transmission dip stick pipe.
5) Repeat above steps for every 100 mile duration (at least 8 times ) until fluid looks clean

Please help me with your suggestions....

Thank you...

Banging when going in to Drive, I would start with checking the engine top mount and the gearbox lower torque link for shot bushes.

You could do what you describe but rather than that as you have no lifting kit I would drive the car up on to a pair of house bricks as that is enough clearance to get under to release the autobox sump drain plug which clears out about 3,5L in one hit.

Only changing part of the fluid will never get it looking fully clean but at least the new oil has fresh detergent properties to flush out crud built up in the valve bodies/ solenoids, a sump dump repeated every 500 Miles and repeated at least four times should be enough to clear it out of sludge, then perform a sump dump once per year from then onwards - Mike

Here's the way I check the fluid myself. Both times, car at perfect level or the reading will vary greatly.

Cold check. It has to be 68F outside. A couple of degrees off, and the level is off by even half an inch. Start the car, keep in P for one minute, pull the dip stick only once, only the very first time, and read which side has the lowest level. If you put it back and try reading it again, it will be soiled with fluid that leaked around the dip stick tube, the reading will be wrong (too high).
The level has to be at minimum at the beginning of the cold mark, and at most at the upper cold mark.

Hot check. It's hard to do, because you need the have the transmission at exactly 176F, a few degrees lower or higher and the reading varies much. There is no way to measure exactly the transmission temp by driving a specific distance or time. When checking the fluid at hot, you can put the dip stick back and pull it out several times, the reading will be good.

So these trannys have no filter in them?
I did the fluid/filter change like E170 talks about in an old '99 Sable a few years ago at 70K miles, it looked dirty when I dropped the pan, the filter looked worse. Did 3 drain/fills.
The Sable is now history, my wife has an '01 S60 w/90K on it that we bought new. Tranny fluid has never been changed.
A few years ago I bought an '02 V70 with 79K on it. The Volvo dealer had been servicing the car since new before I bought it. The previous owner had the tranny fluid changed every 30K.
Guess I'll go to the local Toyota dealer and get a few quart for the S60.

Yes, there is a filter, it's internal (built into the body of the transmission) and it's not accessible for replacement. I have seen a technical exploded components picture where the filter appears. Like I said, it is not replaceable unless the transmission is opened and disassembled.

Great information on how to do the drain & fill. Thanks to all!!!

Quick question: I've read in other parts of this forum that the Volvo dealer must reset the transmission after changing the trans oil so the trans knows there's new oil. It was mentioned specifically in a thread for 2001 Volvo's. This seems really odd and is not mentioned by anyone on this thread.

So, what is your opinions on this - needs reset or not? I have a 2001 V70 T5 with 150K miles on it. I'm the second owner - the first owner took delivery in France on the "purchase, drive and ship to states" program.

Thanks in advance, Denys

I've done this 3 times and never did a reset, nor have I ever heard of this. I wouldn't do that based on my excellent prior experience.

I did put new fluid in my transmission and quickly noticed a hard shifting from 2nd to 3rd gear. Can be due to some issue with the transmission, but there is indeed a 'new fluid' setting in the transmission software. Indeed, on forums there is only talk about putting the transmission into the adaptive mode, the 'new fluid' reset is much less known. I think it's a good idea to have the 'new fluid' reset when replacing most of the fluid. The fact that this setting exists, means the transmission cannot determine by itself whether there is new fluid or not. Given the fact that new fluid and old have very different properties, it's possible that the transmission will benefit from adapting to the new fluid from the software. Without the 'new fluid' reset, it might still behave without apparent issues, but this doesn't guarantee that it won't cause additional stress/wear on the mechanical components.

Oragex,

Did you replace you fluid at high mileage? I did my 1st drain and fill at 70K, and perhaps my new fluid wasn't all that much difference than the old at that mileage. If you did your change at a higher mileage, that may explain the difference experienced. My change was seamless and there was no difference after the change. I'm now at 160K and my car shifts exactly as it did on day one. I now change every 33.3 K and will be due at 166.6K

I did it at 100k miles. It is possible that my gearbox had already an issue.

Here's a nifty little tool/trick I used to fill my C70 transmission. I have a boat with an outdrive unit that I have changed the lower unit oil on. I use a lower unit oil pump that screws into the bottom hole and pumps nicely out of a 1 quart container. I decided to try it on my tranny.

As you can see, the pump has a screw-in connector on the end and that connector actually fits perfectly into the dipstick hole and was even held in place by the dipstick locking tab. Then I screwed the pump pickup end into a quart of transmission fluid and pumped it into the tranny. Piece of cake. You set the quart container down alongside the air intake and it sits there perfectly while you pump. Didn't spill a drop and didn't have to hold a funnel and pour the fluid in very slowly like you do without the pump. You can buy one at a marina for about $10.
