I'm assuming the transmission is operating correctly at this point, and the only issue is the foaming of fluid. Foaming can be caused by several things: Overfilling...which from what I have read is NOT the case. Overheating...which seems to be what your experiencing. It could very well be the transmission cooler is clogged and keeps the fluid from circulating thru the radiator,then back to the trans with cooled fluid. Internal damage...causing the fluid to heat up and foam out of the tube. And lastly, yes, the tube could also be damaged causing fluid to escape.
It sounds like you may have a problem with coolant leaking into your oil. I would check if this is the case, if so you have a bad head gasket.
Thanks,

Hi, Any white foam on the cap indicates water in the oil. Mild white foaming may just be that the car is not warming up properly or its just cold and damp weather and the oil cap is not giving a good seal - can be caused by too many short journeys. Foaming around the dipstick is likely to be more indicative of internal leaking around the head gasket or maybe water in the engine bay from jet washing as a temporary thing. Keep an eye on it an wipe clean to see if it clears up and take the car for a drive in excess of 6 miles or more to warm up properly. Extra indicators like overheating whilst stationary and a rancid smell accompany head gasket failure. Also worth checking the expansion tank as if water is moving into the oil, oil will also move into the water and create a rainbow on the water which is definitely head gasket problems. Poor performance of the vehicle and stalling is also a result of head gasket failure but depends how and where it is leaking. Please accept the solution if it's helpful.

there is no water in the fluid. its just bubbles
i have a 94 firebird, and the trsmission fluid is bubbling out of the dipstick tube slightly after a long drive. 6 months ago, i swapped the transmission, changing the fluid and filter in the process. it is red bubbles, and there is no water in the fluid
i have a 94 firebird with an automatic transmission. The fluid is bubbling out the dipstick tube, but it is red in color, and there is no evidence of water or coolant in it. do you think it could be a cracked filter neck?
thank you so much. you are the third one i have asked, and the other two were complete idiots.
