    Ok, so I posted about foamy transmission fluid and got a few replies about the vent tube possibly being plugged. My new question is.... Can I access it without having to drop the tranny down? My square is lifted 6" and I can pretty much sit under it while working on it. I'm getting ready to go work on it now so I'll probably figure it out but I'll keep checking for replies mean while. Keep on truckin!

    I can tell you exactly where the 700R4's is, but here's a stock picture of a TH350. It's in a better location than the 700R4's for sure. I think the location is universal, but as you mentioned, it may be a bent tube or a check valve. image.jpg

    You can see the small vent on my TH350 on the driver side of the case. Mine uses a small check valve instead of a tube.
