700R4 Pukes Fluid

A friend has a 84 Corvette, He bought the car non-running. Over the winter he had a 383 sbc built and he installed it in the car with the 700 that came in the car. He has had this running and it is drivable. The problem is that when it sits for a couple of weeks after driving, it takes a tranny fluid dump on his garage floor. He believes it is coming out of the vent tube on the trans. If he drives it weekly it wont dump. Trans fluid has to be added to top off each time this happens.
Anyone have any ideas as to what may be happening?
Thanks

torque converter drains back into the tranny as the car sits . The tranny will leak at spots when the fluid level is raised higher than normal as the car sits for a long time.

this is common to all automatics with a torque converter

Thanks, Crosley
Is this something a rebuild will cure? Would he be better off locating a different trans and or converter? I've never seen this before. I have had cars sit, sometimes for months at a time without doing this.
Thanks again

I would suggest just starting the car and letting it run weekly. I have a 700r4 in my Nova and it pukes its guts over the winter, as does the th350 in my T-bucket. Its not a real big deal if they are run weekly though. Also, don't drive it until you refill it.

Check the rubber grommets for the tranny dipstick tube or detent cable.

check all areas on the trans for leaks.

shifter linkage,

filler tube

TV cable area

pan area

clean up trans case and watch for leaks.

sometimes the fluid will travel on the edge of the pan rail.. then drop of many inches from the actual leak.
