I burned out the transmission on my 90 Eldo, 161000 miles. Going to have a rebuilt one put in. now there is steam coming from around the water pump gasket. My guess is that the seal broke on the pump from driving the engine at 5000 rpms for about 2 miles. My question is, can I just put some bars leak coolant sealant tablets in the radiator to stop the leak, or should I replace the water pump. Any suggestions would be greatly appreciated.

First check for tranny fluid in the coolant. The tranny line going into the radiator may have ruptured and over pressurized the cooling system causing the water pump gasket to blow. That might also be why your tranny died, if there is tranny fluid in the coolant.
