[s-cars] Speaking of trans fluid

Paul;

I replaced the rear tranny seal on my S4 around 200,000km. No leaks so far
at 270,000 km - I expect the replacement seal will last 200k. I notice the
seal is wet on my S6 at 150k km, so I expect the service life of these seals
is around 175k km or so.

Mine was dripping on the cats when I replaced it. If the tranny vent is open
you won't get a catastrophic failure - just more leakage as the seal wears.
Eventually you'll have to top up the tranny fluid if you don't change the
seal. You have to remove the tailstock and press the stub shaft out of the
bearing to get at the seal.

Hello All,

  Speaking of tranny fluid, I noticed a burning oil smell at the center of
the car as I was pulling into the shop to get the snows mounted. When the
car was lifted I found my trans is leaking at the rear seal(?). Dripping on
the cats. at the rear connectors. Looks like its relatively new. Also looks
like an exaust soon (that'll be later)

  My wrench says they all do that. Says 2-3 hours and the next one will
probably leak too.

  Questions:

  Severity of the issue, how long till its a big issue?

  Can I travel distances?

  When its done, what else should be done?  If any.

  And will it leak too? He's a compitent mechanic.

  TIA as always.

  Paul
