what is this line to the tranny?

[BPK]

I'm kind of new to this truck, only use it in the snow. 92 K1500 manual tranny. Was looking for an exaust leak and while under there I see this line, looks like a brake line going into a black plug that goes into the tranny. The line is so rusted it looks like it's gonna go any time now. It goes up behind the engine and then i can't see it anymore. Was wondering if somebody can tell me what it is?

There are 2 lines that come from the tranny if it is a automatic. these lines go to the radaitor for cooling purposses. Hope this helps.

If it's a manual it shouldn't have any lines going to the transmission, as manual transmissions do not need oil coolers or even have oil pumps inside them. However, if you have a hydraulic clutch, it may be your hydraulic clutch line, which will probably be rusty anyway. Even if you replaced it now it would probably be rusty again within a month.

 

Can you get us any pictures of the line you're talking about? That would really make it easier.

Somebody identified a picture on another site as the clutch line. This thing is really rusted to the point the nut on the end is coming apart when you touch it so I guess I have to look into getting it replaced asap.
