Transmission catch can placement

[buzzinhalfdozen]

I don't recall seeing anything mentioned in ANY of 40 coupes' posts to indicate what combo, trans,converter, engine ect. so I'm baffled by 1320 know it all advice. I guess when you run a 3500? stall converter you don't build much heat. My T-350 has the vent in the stock location and it will push a bit of fluid at times, My solution bought a small aluminum catch can put a filter in the top and ran the hose from my vent to the bottom of the catch can, mounted it high in LF fender behind the apron. This way if it pushes fluid out it runs right back in to the trans, can is out of sight and no leaking issues. Of course 1320 may have some inside info about 40 coupes ride that the rest of us are unaware of, if so I retract my first statement.Joe

Having literally grown-up in a tranny shop, pretty much any racing automatic may blow fluid out of the vent. No matter how good the internal oil seals and sealing rings are, there is still a certain amount of pressure that leaks by and can blow out the vent. Just like an engine that has a small amount of blow-by that requires a crankcase breather system. Naturally, if the trans gets hot and fluid foams up, raising the fluid level, it will worsen the problem. Filling the fluid to the 1 pint low mark helps and won't hurt the trans. Sometimes just extending the vent by adding a hose run up to the firewall with a vent cap at the end will fix it. A trans-brake car probably is best with a catch can. I wonder how many transmission 1320 Racer has built? My .02.

I have been advising Garret aka 40coupe for over a decade.

Who's converter is 3500 stall? My converter flashes to 6400 RPM and I'm on it for ~ 10 seconds before launching.

1. have always filled my trans to the 1 pint low mark.

2. over 5000 passes and my trans ain't ever puked, maybe I'm just lucky.

3. refer to post #21

I use an old Hellmans Mayonaise jar......
I wire tie it to my frame and drill a hole in the lid......
Works good and who cares what it looks like....
It's just a dragster and you know how they all look alike.
The Mayonaise jar makes mine stand out in the lanes.....and if my sandwich is dry I know where to get some sauce.....

Ed your a friggen menace....LOL

Rich, all those that I have helped online and in person feel very different.

BTW, Ricky's engine let go on Sunday.

[Rich Biebel]

Sorry to hear that Ed....What broke?

Why pray tell would ANYONE be on the converter for 10 seconds? GEEZ don't you have the coordination to deck it when the tree cycles, bet that dumptruck motor spins right up to that killer converter.It's obvious that all your "advising" has got Garret on here asking for input. Why would you care if he wants to set this up the way apparently his trans guy ADVISED him to? BTW you never did answer my question exactly what class of Super Stock is "E"? You stated that in fact you had a legal Super Stock car, it must be another ride since in your pics it's clearly designated as E something. Could it stand for EGO? Good day sir. Joe

Rich, you'll know before we know. All I can tell you is that both sides of the block are windowed.

The new trans isn't one of my home built 400's but rather a class TH350 that came with a fitting in the top rear and the factory vent was plugged.
