Its a blow en head gasket. The head will need to be inspected by a machine shop. (make sure its not cracked. If it is cracked that's what caused you head gasket ot blow. Now your talking about over 1000 to fix it.) It could also be a cracked block.
It sound like shift solenoids. There are 2 of them in your transmission. They are not very expensive to replace at a transmission shop. You should take it into a transmission shop and let them look at it. You could me doing more harm by driving it that way. The longer you put off fixing it...
