a4ld transmission leaking from bellhouseing!

[chessman21]

a4ld torque converter short pilot

I replaced tranny/TC long pilot with another one that may have a short pilot...

Would that have anything to do with fluid poring out the between the bell and block as soon as the drive train reaches operating temperature?

Iv checked vent hole and cooler lines up to the out on secondary cooler with no blockage and good flow..

Trans cooler lines are the same size and don't have a direction since trans cooler is just a reversible in/out.
There is an IN and OUT on the trans, but reversing the lines wouldn't matter, because of above.
If you want to know:
Lower one is OUT to cooler
Upper one is IN from cooler

Yes new torque converter could be the problem, cracked or wrong size so not sealing at the trans bushing, or front seal on the trans is blown.

A4LD had an offset trans seal because of some bell housing, many just centered it and installed it but that will cause it to blow out since all bell housing may not be centered.

Read here:

If you have repeated front seal blowouts on A4LD's it may not be a problem with the seal or the quality of your work. Your could have a bad bell housing. The bushing used in the A4LD is finished in place. Because of this the bore that the bushing fits into doesn't need to be in the center of the bell housing, and in many cases it isn't. When you're working on an A4LD you need to check the bell housing bushing to see if it's the original factory bushing. If it is, and it's not worn (no more than .003") converter hub to bushing clearance), Don't Replace It! If the bushing needs to be replaced, you need to make sure the replacement bushing will fit in the center of the bell housing. To do this bolt the torque converter to the flex plate. Turn the engine over and check the run out of the converter hub. Now bolt the bell housing to the engine. If the Torque converter is contacting one side of the bushing excessively, the bushing is off center and the bell housing MUST be replaced. However, a slight amount of contact is acceptable. By checking the bell housing first you can avoid repeated front seal blowout.
