Hi,

My 1990 Legacy automatic transmission has developed a leak.

For 15 years I regularly checked the ATF level, then bam, one day it was low.

The leak is from a gap cut into the the transmission housing, but is actually the ATF pump.

 

 

It is leaking about 300mL per hour of idling.

 

At 25 years, a transmission teardown just isn't in the book.

 

But Josh slightly suggested a chemical fix.

 

My question is: which seal is leaking, and what chemical leak solution is most likely to stop the leak?

Trans-X seems good. I found many happy users. I don't know what causes slipping, or if slipping is a part of leaking, but I just have a leak. Hence, I'm trying to select something that directs all its energy on stopping my leak. The nature of which, btw, I really don't know.

 

Thanks for your help.

trans-x works supposedly by making seals pliable again.

 

 

it's getting to be a pretty old car but, maybe a used trans could be found (how new of a trans would bolt-up?) - might have a lot fewer miles than your present trans too.
