Coolant is leaking out

I would think maybe the water pump is leaking you will have to put it up on jack stands and wipe everything down under the car. Then if you start it for a minute or two shut it off you should be able to see where it's comming from.

transmission line is loose @ connection, or has a hole(leak) in the line, even a crack in housing. trans is a large pump, high pressure, if you have a leak, just start your car and look under it, you'll know real quik.

What you are describing sounds like what's called a freeze-plug. These are round plugs or inserts in the engine that are designed to pop out if the coolant should freeze to avoid cracking the block. the orange goo is rust mixed with coolant. This indicates that the freeze plug is leaking coolant and should be replaced (not a major job).

Check the bottom side of the water pump for wetness, as well as the lower radiator hose. The water pump if leaking, will run the coolant down the front of the motor,and can appear to be coming from the top of the oil pan. It is nearly impossible for the top of the oil pan to leak coolant.

Is it leaking FROM the oil pan, or dripping OFF the oil pan?

If its dripping OFF the oil pan, that leads me to beleive you have a coolant leak somewhere. Check the coolant level. Check for leaks.

Check your oil, if the oil is milky/coffee colored. Or if your coolant looks kinda nasty, you may be looking at a headgasket.

I believe u are referring to the tranny pan. And if u are loosing that much fluid I would start looking around the block for any sings of a blown head gasket. If u live in colder climate it could also be a freeze plug that is bad. In Minnesota I see this all the time. People think they can do there own coolant flush and end up putting to much water in and freezing the block partially and when it thaws loose coolant from that plug. I would suspect a bad rear seal in the motor or a bad oil pan gasket be the cause of the oil. But without seeing the vehicle and the leaks I cannot say for certain but those are the things I would think it to be. Now no offense to you at all, but I think I would take it in to a shop to find the problem, or a food friend that knows about cars, like what a tranny pan is. And like I said no offense to you. But to me this sounds like it could be a big deal of work not for the novice.

First you need to identify what's leaking? What color is fluid? Green, Red, Brown? and where under car is fluid leaking from center, front rt, etc... Another option is check ALL fluid levels - coolant, oil, power steering, transmission.

If the leak is back there? sounds like an intake gasket or head gasket if you ruled out the hoses

On an automatic tranny, the tranny oil pan is removed to drain the tranny fluid - a somewhat messy job. Typically when this done the tranny filler is replaced. A new pan gasket is installed in this procedure.
On the manual tranny, there is a drain plug at the bottom side of the tranny to drain the oil.
I have used a home made setup using a suction pump with small diameter tubing to **** the fluid out from the tranny filler tube. This is when I was replacing the filter and I dropped the pan. I did the suction routine to avoid all that fluid dripping out when you loosen the pan.
Have you located the leak? Is it from the tranny oil pan or maybe from a tranny cooler line?

sounds like u have a cracked oil pan, requires removal from engine and either welding or new pan estimate cost around $300 and up depending on location and if other damage
