Auto Trans Fluid Leak
My '95 K2500 Suburban is leaking atf and I'm having a hard time locating where from. What I noticed is fluid on the ground behind the right front tire. I look into the well and I can see it is damp toward the rear, but the inside face is wet, so are the trans lines running along the engine, the front of the starter, and forward of the r/f wheel on the little brake box on the outside of the frame.
I run the truck and see nothing spraying, dripping, or seeping. Most only happen under pressure. I suspect the trans lines. First, because these trucks have issues with lines rusting out. Second, because the lines look clean and great everywhere but along the area where it is wet. There are patches and lengths with surface rust. Also, this is where they are held tight together, which I can see causing corrosive crap held between. The lines are also fairly level there. Third is all this leaking is forward of the transmission, so the trans lines to radiator are the only place I can think of trans fluid being that far forward. I figure on patching that length in on both lines first. I hope that's it. I came here to see if maybe someone else had the same problem with a direct route to the problem. In one way the lines seem the obvious problem, but in another it doesn't seem right. That's because of where and how I see the fluid hitting. It must really spray out of there when driving. I just noticed the wet spot the other day. Fluid level is still good. Any help would be greatly appreciated
