Hello all, this is my first time to post. I have been reading the forums for a few yrs, and I really like this site. I have a 2000 F150 with about 240,000 miles. On Tuesday I had a freeze plug bust, and so today I replaced it. However when I turned the truck on, water began leaking from the casing where the tranny meets the motor. I'm sure the answer is yes, but is this something major, or is there any reason to believe the truck can be fixed for a reasonable price. The truck drives the same as it did before the plug busted, but I dont want to screw anything else up.
by the sounds of it i would say you blew the freeze plug on the back of the block.. in order to change it you have to seperate the transmission from the engine to access it... i cant remember if you have to drop the flywheel also to access it... once into there replace it like you did the other one you already did... and yes if you run it that way you will keep dumping coolant out of it and without a constant supply the engine can/will overheat and possibly cause more damages.. as far as the cost it depends if you can and are willing to seperate the tranny yourself or with help of a freind.. or you can find someone who is more experienced if you are not... its a pretty straight forward job though especially if you have a repair manual to see how to drop the tranny if need be

Once you fix the leak by the transmission, I'd recommend figuring out why the freeze plug broke in the first place. Did it rust out or did the antifreeze mixture actually freeze because of improper mixture of antifreeze/water?
It was probably a little bit of both, but mostly the mixture Im sure. Still wondering if anyone else has any info about what may be the cause. Also how much would it cost to have the plug behind the tranny replaced. Truck is very old, and I dont want to spend a bunch of money on a truck that isnt worth much.???
you really dont know for sure untill you look and see if the plug was popped out, or the block cracked due to freezing. Get under the truck, take off the little shroud next to the flywheel. See if the plug is laying there. Look inside with a mirror and see if you can see where the leak is coming from. Eventually you and removing the transmission.

I've got a '97 5.4L sitting on my garage floor, I'll take a pic of the back but it seems like the flywheel will cover those plugs up, you didn't say which engine if it is a V6 this won't help. The plugs are definitely covered by the flywheel, pic with flywheel removed:
