I have a leak in the coolant lines. I just put a used motor and used transmission in my z71 and I pulled a spark plug wire off of 1 cause it wouldn't start and I seen a drip of transmission fluid on the tip of the plug. Just wondering if the transmission fluid is getting into the motor somehow.

No it' s probably motor oil drive it and see if it cleans up if not then check for a bad valve seal or head gasket.

If it is running down the block behind the distributor it's either the intake manifold gasket or head gasket. Get it pressure checked It may be a freeze plug but I kind of think not. I don't remember if they have any in the head or not.
