What's leaking when the bottom two bolts of the transmission are missing? Appears to be oil but where from?



Also, the two hard lines screwed into the radiator on the pass side. The bottom one is the out? Is it common for this connection to leak?



TIA

Where on the trans are these bolts? Is the fitting in the rad leaking or the line going into it?

There's two leaks... One appearing to be oil from bottom of trans/engine where it bolts together. The bottom two bolts are MIA. What size are they so I can get replacements? What grade do they need to be? No one local has any extras.


The second leak is at the fitting that goes into radiator just above the bottom rad hose outlet. I couldn't spend anytime trying to tighten the connection to see if it was loose. I will the next day it's dry out.

In the mean time I'll try to get a pic.
