Also inspect the tailshaft seal (where the driveshaft connects). When i first go my car that seal was cracked... it didnt spew out like yours but it leaked fair enough. If its that then your in the clear! Its a cheap seal and will take 20 minutes to replace. (Be careful of a torrent of tranny fluid when you pull the driveshaft out!)

If it's leaving a thick trail like he describes, I'd think it is some place with the trans fluid under pressure. Probably the front pump seal, or a leak at a cooling line.
More information from coupedaveill would be helpful...

Thats true... i would check the lines while the car is running, the front seal has to be checked under load and thats impossible... however there should be some leakage at idle, just get under there and check it out!
