Hi, I have a 95 Blazer 2wd 4.3. I installed a external trany cooler and then my upper Line at the Transmisson is leaking. (not my new connections up front)
Does andyone have advise how to tighten or change it. And also correct tool? (13m wrench) It is very tight up there.

Thanks,
Rsither

Hi,
I figured it out.
Long extention ratchet with a crow 1/2 inch end.
Tightened and stopped my leak.

Thanks,
Me
