I have the vent in the top rear of the main case. At 1/2 quart low it still pushes enough fluid out to make a mess. I run a B&M deep cast pan, so there is plenty of fluid capacity. How much are you all running? Anyone running a catch can?

I've seen people put the rear vent on the front side of the rear bulkhead (above the band/drum) that ends up making a mess. Putting it at the very rear of the case, drilled into the cavity under the rear support, I've never had one leak. Even putting it in the extension housing, it picks up oil slung from the output shaft. Not sure where your's is located.
If the results don't match the theory, change the theory.

Mine is located at about 11 o'clock on the main case one inch from the tailshaft housing. I will have to check on the guvnor feed hole. I did add a puke can of about 8 oz capacity with a 3/8 hose from the vent tube to the can, but there was still fluid dripping off the whole rear of the trans plus a couple of ounces in the puke can after seven passes. I clamped a screen to the end of the hose to try and separate out the oil, and will run less fluid, will try a quart low or so.

Great question Greg! Mine pukes a bit too. Need to take a peek under the car! I'm building a new trans for the Charger and was about to ask where to put the vent. Thanks for the pic, CMcAllister. Tim

We know that launch forces must send the fluid flying to the rear of the case on launch. I always thought that the deep pan was to keep the filter covered so the pump doesn't pull air. But if you think about it a second, low gear has little demand for pump volume, correct? Would that allow for any air drawn in to be cleared out? So the question becomes how deep of a pan is best, or minimum for faster cars, and how much can the level be lowered before trouble. Cab, I see you run all your TFs 3/4 inch low roughly. Never any problem, I take it?

I always had problems with the puke. Pushes out 1-3 ounces after every run when i let go off the throttle. +9000rpm. I have vent relocated exactly like the picture. I just installed a metal can in the firewall where the hose is at the bottom. It pukes there and drains back automatically, no problem ever since.

No problems yet that I know of I use the Mopar stamped steel deep pan kits usually I have one older Pro Trans fully tricked out 727 SS/AH tranny Dave did years ago that has a B&M aluminum deep pan on it, it has a slosh baffle welded onto the back oil pan rail to help keep the oil from slosking back into the tail shaft housing

My buddy was moving the vent because it leaked most of the time when it got hot... I gave him my 727 book that shows that pick and I told him what to do... he even put a hose on it running up to the firewall but no bottle... so far he is fine... only did it hot
