Need VADIS - Transmission Leak 98 XC70 AWD

Post by **osman** » 24 Oct 2012, 16:38

There are so many places where this leak could be from. I wish I could see the Vadis for Front Transmission Seal. The Bevel Gear and Box and Such.
I cant tell exactly where the leak is coming from or what part to order. I understand there are several seals. It is definitely coming from up top, in front.

There are two cooling connectioins on front as well as the front pan and on top is selector shaft seal.
There are several test port plugs on the gearbox.
Front seal behind torque converter is going to run out of opening on bottom of bell housing.
The way it is found in a shop is to spray wash things and then lift out air cleaner and reattach it up on strut tower tied out of the way and then dry the water and run until you see the leak. Mirror may need to be used to spot it.

I think it my be the front seal. I know its not the cooling lines. VADIS anyone?
Thanks for the input.

These should pretty well cover the seals.

any tips on replacing the front seal? like anything else I should do at the same time?

Is the front seal the seal that goes around the solenoid access box?

If you are talking about the input shaft (Torque Converter) seal then I would change the rear main seal on the engine while I was at it. The only thing additional you would need to remove is the flex plate. The transmission and the angle gear need to come out of the car to get to it.

If it were me going to all of the effort of pulling the transmission and angle gear I would be inclined to change all of the seals on the transmission. That really isn't a job you want to do more than once.

Well it leaks only while driving. Not while its sitting and not when its idling. I dont know if that is a clue about which seal or where its leaking from. We plan on pulling the trans after the holidays. Anyone who has advice or anything it would be much appreciated. I definitely want to fix it once and right.
