When installing the trans catch can on the firewall, the can has to be higher than the top of the trans. Seems obvious but do you run the vent hose out of the trans on top of the bellhousing to get to the front side of the firewall?

I've been racing over 30 years and never had and still don't have a trans puke can on my door car(s).

You have a trans issue! Fix the problem, don't put a band aid on it.

I run them up the dipstick tube

I never had this problem either until I got this case. I've had it rebuilt at least twice and results are the same. Neither of these builders have a dyno so maybe I need to find a builder who can test it, although I read a post about Rossler sending one out that he dynoed and it still pushed fluid out. Pulling it out isn't easy for me anymore and not knowing if another rebuild will actually fix it makes the band aid approach appealing.

Ron, maybe it is a case problem but your trans builder should have identified it. So who are the trans builders that have rebuilt it twice?

Send it to Rossler and not only won't it push fluid when it comes back but you'll run quicker ETs too.

I have never had a problem with transmission overflow but I do run good cooler with good PTFE? lines.

Have been told NHRA requires a transmission catch can.

Fluid level too high when hot?
I've never boiled my car over but have a tank on my radiator. I made a tank for my trans and used a clear hose on it and would see vapor in it, no fluid in can.

I use this, as some of us have to use them by rule, advanced ET and TS. Mounted to the firewall and I plumb the line to the bottom, vent on top and if anything got into it it can gravity feed back into the trans.

Al, you are correct in part that per the NHRA Rulebook, TS is required to have a trans puke tank but Advance ET is not, TD is also as it's rules come from TS. Now that said, tracks can require MORE than the rulebook states but being that tech is all but non existent, it's a safe bet that once you pay your entry fee you are good to go.

I have had an overflow trans tank in my car for several years, I check it frequently and it has always been dry. If the class you run requires that you have one the solution is obvious, install one even if the results are the same as mine. That one time that it does overflow and sprays trans fluid under the rear tires can ruin a great day of racing, and the car.

i tapped into the puke tank for my vacuum pump and ran the line there

So NHRA does have a rule about the trans overflow tank. Hmm.... Just not for slower cars.

I had to actually go look at the rulebook as I was curious. I actually is ONLY on TS not even for TD. I will also say as far as rules enforcement the closer you get to the mother ship the more they seem to get enforced. I assumed it was an advanced ET deal as I was asked about one at a bracket race because my car said TS on the door. Just another one of those rules that make no sense. I have to have one to run TS but I could go 6.50 bracket racing and its ok. Like the diaper rule, and some of the S/St rules. Or even the clothing rules that start at 7.49 but not until 4.50 for 1/8 mile. Or the 7.50 cage rule that does not have an 1/8 mile equivalent written anywhere. But I digress.

Actually the TD rules say to refer back to the TS rules, so the puke tank is required in TD. IF a track actually had tech, they could refer back to the ET breaks for TS and TD to enforce TD and TS rules like a trans puke tank, in advance ET but the bottomline is a trans puke tank is not required in any ET class or sportsman class except TD and TS.

Rules are rules, but put that all aside doesn't it make sense to have a puke tank just for safety sake?

I think that is a good point. I don't currently have one but think the addition would be an added safety insurance.

No, if your trans is built right, it don't puke. What does make sense is requiring every car to have a diaper or belly pan.

That said, I'll bet that at least 50% of the bracket cars that are required to have a diaper don't because no one cares, no one is checking, there is no tech.

I've never had fluid in my trans puke tank, but I'll always have one, can't hurt. Same goes for the diaper.

You're probably right that there are a bunch of bracket cars out there without diapers.......and tech is pretty much a joke anymore at local races.
