Need help identifying tranny leak
Have some tranny fluid dripping on the garage floor. Changed pan and filter a week ago, as well as engine pan, in hopes of eliminating all leaks.
Still have tranny fluid, but not coming from pan. Appears to be dripping from the area at the back of engine. It is possible for a torque converter to leak, or do you think it is possibly an input shaft seal. Leak seems to trickle down by the flex plate area.

Just a thought, have you checked the cooling lines to the radiator. Mine has a leak in the line right where it starts to come up to the radiator but the fluid goes back down the borrom of the line to make it look like the leak is coming from back there.
Again just something else to check out.

Either the front seal or a leak around one of your front pump bolts. It can run over your torque converter, and when you fire up the truck the fluid gets flung all over the flex plate. You've obviously popped the inspection cover. What did the front of the pump look like? Front seal leaks are generally easy to identify.

What about the dipstick seal? That one was a MAJOR pain on my 700R4...
