transmission fluid leak

[kendl77]

i have a problem with my transmission where it leaks fluid after it has sat a couple of days...my first encounter was a few months ago when i took it to the body shop and the shop owner told me after sitting for about 2 days there was a big puddle of transmission fluid under the car...it seems to only do it after the car has been sitting...anyone know what the problem could be...the transmission is a 350...i recently replaced the trans filter and the trans pan gasket

See if you can find out where it is leaking.

Some problem here. I think I have a leak in the selector shaft seal, bought the seal and a special puller tool, but haven't gotten to it, seems to have slowed down though, wondering if it's gumming up....
