Transmission catch can placement

KRatcliff · 04-30-2012, 08:48 PM

If you are not puking or leaking fluid out of a racing transmission just means you haven't put any in yet.

It's not currently puking and never has. The vent under the shield has been plugged and a new vent tapped in the rear portion of the case. That's a much lower place on the trans and it has been recommended to me to put a catch can on it. This is a new setup and I don't want to put fluid down and learn the hard way. Just being proactive.

I put mine on the firewall on the passenger side. Any fluid that might make it up there drains back slowly.

Why? My vent remains in the stock location and it too is under the shield as it has been since I first starting using a shield 13 years and thousands of passes ago, all without puking a drop.

Do as you wish with your car, might want to install a parachute too.

That's a mystery and I don't have any clues but am doing what has been recommended since the vent is in that location.

be careful of who you listen to, there's no reason to be plugging the stock vent and relocating it on your trans!

40Coupe,

I use one on my stocker. I run line from the factory vent to the trunk. I can access it easy and it has a long line to drain back. I have never had and issues with my C6, but the C4 always left a little in the can when hot lapping.

You can run a line tight to the tunnel and back into the trunk for a clean look. I use a polished aluminum can with a breather, looks nice and its out of the way.

This info pertains to racers who use a T200,... not commonly used in bracket racing.

If ONE were to study the path of the fluid slung off of the direct drum and other internals, and passed through the pump and out the vent, ONE would see the problem. Those things weren't designed to spin at 7000 rpm.
Baffling the vent passage won't work because the direct spins both ways.

I have run the vent hose up to a nipple, brazed high up on the vent tube..That works fine but won't work with non OEM locking dipsticks (Yes, I said "dipsticks" in this post)

The easiest thing to do is move the vent to the rear , as was used on some of the early 200's .The boss is already there on the case.
Again , this info pertains to CLASS racers who happen to be following this thread.

Anyone needing "advising",, PM me... LOL

That would be a good problem to have. That would mean I tripped 150 MPH in the 1/4, a really good problem. LOL

My setup is like Ken's, never had a problem when I ran the 400 trans with the 200 I'll lose a little. Most stk and ss don't use trans coolers so that fluid can get hot in the later rds.
