Hi all…I just bought a mostly restored 46 ¾ ton pickup and found out that it looks like I may have a small leak in the rear freeze plug on the back of the block. I am looking for some advice to stop the leak, rather than pull Transmission off and replace the plug. Several friends (I hope) said to buy some good radiator stop leak a mix it with the coolant. Any problems with that or is there a better solution.

Thanks…John
