I am having some non critical leaking on my 2002 V70, 2.4t.
The exploded diagram you have shows a gasket between the case and the steel cover on the front.
Volvo said there is no gasket on my 2002 trans.
Is that correct??? And why is the dipstick located directly below two hot hoses????
That makes hard to see and not possible to check level when the engine is warm.
When I brought it to the local mechanic he wanted approx $600 to repair.
If that was the only issue with the car it might make sense.
Since I don't have any resources I thought I might try it myself.
Two of the Torx fasteners cannot be accessed without removing the trans.

Is that really leaking? Maybe with a cold transmission, just rub a little the sealant where it leaks, clean nicely with some brake cleaner, then apply some rtv from the outside. Should make a decent fix. That cover is sealed with sealant and yours has been removed and the valve body repaired, so hang on it. Don't bring it to that mechanic, you may leave with it working worse than before (some mechanics like to keep good parts for themselves when they find one). Really no need to start removing that cover, you need to lower the subframe plus a few other troubles.

As for the dipstick, well you are not the only one who doesn't like a 2nd degree burn just to check the transmission oil. Maybe when the engine is cold, try to move those hoses or place something to keep them tossed away, so later on it's easier to check. Gloves also help ;)

Thanks for the info, suggestions and humor.
I don't know exactly where the leak is.
So far, monitoring it is the best I can do.
The offending hot hoses are too rigid or held fast to move.
I'm thinking It would be easier to bend the dip stick tube to the right.
The tube is fairly stout so I'm not going to do that on the car.

Here's what I do now to check the transmission fluid level. I have a 2001 Volvo V70, not sure if this works the same for all years or the XC70 model.

Remove the cold air intake snorkel between top of radiator and air filter box. It just pulls out so no big deal. This provides extra room needed to use both arms/hands, which I now use to check the fluid level.

Loop a large nylon cable tie around the lower radiator hose. This loose fitting loop creates a handle and allows pulling the lower radiator hose to the right and giving a more direct shot at the dipstick. Previously I would push the lower radiator hose to the left and pull out the dipstick but it was still at an angle and I would bend the dipstick, not to mention the hose is hot. Using heavy gloves is really cumbersome, especially with a fragile plastic dipstick.

Now I use the cable tie looped around the lower radiator hose to pull the hose slightly to the right with my right hand, which enables pulling the dipstick straight out with my left hand and then insert it back in the same way. It also provides a better view of the dipstick with the hose pulled to the right. This has worked out much better for me while trying to get just the right ATF level when hot.

Sorry this message was never answered.
I don't see why or where I can get notifications for them.
My current dip stick has a cable tie on it.
I'm thinking of attaching a jogged handle to it.
Should be easily fabricated.
I'll take a pic after I do it and post it on here.
Thanks for the advice.

Crazy... but... How about drill into the housing near filter, tap a thread there to use as a plug later after getting a flexible magnet recovery tool in there then insert bolt/plug. Obviously a chemical to dissolve the clog is still best.
This gutsy suggestion has now saved four Aisin transmissions across a Fora here, thanks to the guts on this thread.

Firstly.....thanks to the members here for the great information for Volvos in general and specifically this trans issue.

Recently purchased a very base model 2000 V70 with trans issues. Currently has the whining trans sound but does engage in reverse and forward. Its a bit blurry as to what the previous owner has done. He did mention that a couple drain and fills had been performed on the car but as a daily driver it wasn't able to past muster. The car was delivered on a trailer by the previous owner and the extent of me driving the car was to engage the trans and back it off the trailer.

I've read this thread close to 20 times to confirm my understanding of this trans. I'm coming from an extensive 850 background and this is my first foray into the 5 speed trans and what appears to be its own set of problems. Everything is on hand to do as precopster has done......Magnefine filter.....drill......12m x 1.75 tap.....12m x 1.75 screw.....washer and rubber washer etc. Have one question and another idea that I would like to propose to the group.

First the question.....I want to confirm that the proper placement of the external filter and direction. The flow is from trans to radiator of the line that is located at the top of the radiator, is the correct line, location and direction?

The idea.....I'm assuming I have a clogged filter and am curious if the blockage can be sprayed off the filter via the newly drilled hole. I have a piece of spray tubing that comes with the Seafoam spray lubricant that is 14" long and have attached a normal length of spray nozzle, by heat shrink tubing, to that for a total length of 19". Do you think its possible to spray the crud off the screen and have it wash (fall) to the newly drilled hole or the drain plug area? If so what should I use to clean the screen? Carb cleaner, seafoam spray, brake cleaner......?

Very curious to hear your thoughts.

Cheers!

Upper hose is a return line (from radiator to transmission).

So my inline filter needs to be in the lower hose then.
