That stuff is color coded. LLOL Coolant is supposed to be GREEN like antifreeze. Tranny fluid is RED. Coolant has NO reason to be IN the x-mission. IF its GREEN, look higher on the motor.

They rephrased my question =( I know it's not from the tranny, it's just pooling on it. The lower radiator hose connects to a steel pipe which leads into the engine. I think it's leaking from inside there and running down my tranny. What could cause this type of leak?

The pipe above the transmission is the water pipe wich lead to the back of the water pump. There is an "O" ring where the pipe attaches, and that MAY be bad, therefore causing a coolant leak. More likely, the water pump is going bad, and leaking internally and running back down the tube and onto the transmission. If the water pump is bad, this is a MAJOR headache repair job for the DYI'er. I recommend putting it in the shop. The "O" ring will be a dealr item and cost around $3.

Coolant should not be leaking from your transmission the only fluid in your transmission is transmission fluid. A faulty transmission seal can allow transmission fluid to leak out.

Your transmission fluid is probably leaking into your coolant

There is a heater hose that goes to the left rear top side of the intake manifold and that fitting leaks engine coolant sometimes and it will run down the back of the intake around the distributor. If that fitting is not leaking then the intake manifold gasket is leaking coolant in the corners of it. REplace the intake gasket. That's all that can leak coolant on that year engine. If coolant is leaking out between the transmission and engine block then you have a freeze plug leaking in the back of the engine, between the transmission and block. Must remove the transmission and flywheel to fix it.
