1999 v70 base transmission fluid massive leak

cbdbcbdb · Post by **cbdbcbdb** » 07 Apr 2014, 13:55

Can't keep tranny fluid in this car. It drips while driving and when parked just pools under the car. Put it on stands yesterday and cleaned it off. Had my son start it while I looked for leaks. When he shifted into gear the red fluid came flying out of the little opening with the gear teeth. It looked like the teeth were spraying it up and out. There is also a weephole at the bottom of the bellhousing but it was dry... isn't that the same chamber?

My suspicion is a transmission pump seal. Could it be something else?

Thanks.

Is this a stick or auto tranny?

Its an automatic.

After looking online a bit, I see transmission pump seals and torque converter seals. Are they really the same thing? This one (which is Genuine Volvo) and this one (Aceomatic?)...

I found several diagrams of the AW50-42LE transmission and some rebuild kits as well. Not sure I want to crack the case. The car has 180K on it, but it shifts well. I'll start by fixing the hole in the dam.

Thanks!

Are the flex plate bolts removable with a 12 point socket, or do they require an eTorx socket?

Who cares about the Flex Plate bot type?? The man is only asking how difficult/what procedure should be taken to stop the leaking!! If he needs a 12 pointed ratchet or Torx head sockets, well he'll hafta use the proper tools... I don't see ANY assistance given this poor guy, or anyone else who's looking for accurate information regarding fixing transmission leaks on their Volvo. It'sa shame too....

It was the OP who asked about these bolts so apparently he cares. The bolts that attach the torque converter to the flex plate are T50. Here is a DIY with lots of pictures, available via a simple search.

There may not be a lot of instance response to this thread because there are not that many who DIY there own transmission repair, and those who have may not be online today. It would appear the OP has a blown seal. Getting to it is a tall order in the home garage, but the above thread goes through the procedure step by step right down to the size of the tools needed. Considering the labor involved, wisdom would dictate using only the Genuine Volvo seal.

To the limited extent of my understanding, the inspection hole at the edge of the flywheel is the same camber as the bell housing, but give it a little time and someone can more precisely diagnose the source of the leak.
