I' sure the tranny is completely shagged and will require a $3000 high peformance replacement for my application..that would be par for the course.
this thing is about to go up for sale in bits and pieces...that would give me some jeep play money :-)

That's the vent. I think it's probably overheating also. It would really take a lot of extra fluid to just overflow there and you'd know it was way overfull from the dipstick. Hmmmmmm...didn't you post earlier that you put an aftermarket dipstick?? Are you sure that the tube and dipstick are the right lengh so you aren't getting a wrong indication of fluid level?

LOL. That's one way to do it...LOL. Seriously, don't give up on it now. A C6 can handle a lot. It surprises me that you're having so much trouble as they're pretty rock solid. You can really do one of these cheap too. You can buy a good C6 for not much money. A build kit can be gotten for less than $60. I have less than $160 in parts in mine...that includes a complete rebuild kit, new clutch plates as well as the frictions...new band, new filter, shift kit and remanufactured converter. If you tear into it you'll find that they are not that complicated...you can build one alot quicker than you can the engine. I know the stall converter will run you more but still you can build a really good C6 for not much money.

connverter is a TCI Saturday Night Special and is new (less than 200 miles since I installed it), like $180
tranny was rebuilt no more than 10,000 miles back ($800 rebuild)
maybe I've got some exhaust in contact with it. The starter is struggling as well. I have not really snugged up all the exhaust clamps etc. Guess I better take a look under there.

Good luck with it. I do think that the only reason to get fluid out the vent is from overheating. If you don't have it, I'd put a temp. gauge on the trans so you can verify fluid temp. That'd go nice with all those other gauges anyway...lol. If it is overheating you've got to figure out why. You can verify flow through the radiator. I hate to pick on your converter but these stall converter's add heat. Did you add an additional transmission cooler? Depending on the gearing and the converter, you might be getting alot of slip on the street driving, which is where you get all the heat from.
Again, good luck.

My thoughts exactly. Need to do some investigating.........
1) heavy truck
2) gobs of torque
3) not alot of gear
4) bigger than stock tires
5) looser convertor.....
all add up to possibility of heat...more than a stock cooler in the radiator might handle. You said that it happened after a few runs, and driving it to the track?? Then all the way home?? After a big smoky burnout by stroker??
Hmmm, I smell trouble.....

4.10 gears and 30" tires??? seems like I have plenty of gear and short enough rubber in my opinion. as for the rest of your list, Guilty as charged. Although the TC is supposed to have a conservative 2200rpm stall behind my FE (according to the TCI techs).
I'm starting to think it's my exhaust. The collector clamp may be laying against the tranny, providing a direct metal hot-link (not the sausage) :-)
If my friend ever shows up with his Harley he wants to change the motor mounts on.. Then I can get back in the shop and check out my exhaust, and maybe put in some shields.

Greg did you also rehook-up your add-on trans cooler and fan?? And yeas if you dont have a couple inch air gap from the exhaust to the tranny... and or close to the tranny cooling lines..it will get the fluid to foam up... And your converter will act looser with Super heated tranny fluid...It will get Oxyngenated fluid instead of pure fluid making it act loose.. JMO!!!
Good Luck Bro!! Your getter fixed!!!

That combo is not bad, but with a heavy truck and those stats they are a bit soft yet. Not that they are bad....but they could add to the heat problem is all I'm saying. Ya, the exhaust laying on the tranny case is also a bad thing.
As long as the fluid does not smell comletely burnt, you're probably still okay. Let's keep the fingers crossed!

From my experience with C-6 trannys you are looking at a vent baffle on top of tranny ... that's all that's there on all the ones I've seen. I think Freightrain's comments about overheating, "slipping", and tranny temp gauge are all right on the money. My experience is limited to normal stall torque converters and if your torque converter really has a stall speed of 4500 rpm, as you've mentioned, that could certainly overheat things up in a hurry ... expecially street driving.

No burnt fluid until it exits the tranny and hits the exhaust.
the TC stall is only 2200 rpm, not 4500 as somebody joked about earlier :-)
I buttoned up the exhaust yesterday. The passenger side collector is right next to the transmission bell-housing and I didn't even have the collector bolted together. So, the collector flange could have been touching the transmission and there was probably a lot of hot air escaping there. It's now sealed up as are the rest of the clamp connections. So, I got rid of all the exhaust leaks as well (not that I was worried about those yet).
Now it's raining. I guess we needed it. but that limits my GTech playing. Good sleeping weather, and I have to work tonight.
It will be a few days until I get back to the truck....

You may have your heat source there. It's raining here too. I was out till after 1:00 this morning with kids at the Harry Potter release...then work called at 7:00 with a problem...dragged my butt out of bed and up here to find an operator didn't reset a counter...took me about 30 seconds to find the problem...damn the luck...I hate it when they don't handle the simple stuff. Think I'll head back to the house and have a beer. With the rain I might even be able to enjoy working in the garage...or at least sitting around and having a few beers....LOL.

I have 4.56 gears and 29" rubber on race car, and with a 3.25 first gear in tranny.....it's easy movin 4100 lbs. Well, sorta anyways.
Yup, rainin' here today. Air so thick you can cut it with a knife!
Sure wish it was a "dry heat".......LOL!!!!!! Dog days of summer are HERE!!!
Getting ready for picnic tomorrow..........(shhhh, it's my B-day). Suppose to be the same weather again.
