1999 S70 AWD ATF LEAK

I’m seeping some ATF from the front of the trans. I’m guessing o ring on lower ATF hose

AS we always recommend, clean, run and re-check. I don't think that bottom pipe is leaking. Hate to say it it looks more like an RMS which is often a symptom of standing for a long time. Try some Blue Devil or AT-205 RMS sealant if it is now available again in the engine oil and take it for a good run. I had a similar issue with the California bound 850 which started to leak on the run to CA. A bottle of Blue Devil in the oil just short of Reno and all was good by Santa Rosa. Still not leaking 6 years later.

Oil at the A/C compressor might be PCV which might also explain an RMS assuming that is it.

Point of Note!! Check your second picture above. Look at the upper mounting bolt for the A/C compressor!! EEK!

Umm, should we be worried when you show the whole parts thread?? Hopefully you need little if none of this!

Looks like Transmission main seal, serp from the weep hole

That is not a fun seal to do. Ask my local dealer! They had to do it twice to get it to seal.

Maybe worth a shot at throwing a leak-stop type trans product?
