first time new truck

[cammed99]

got the trans in an i have a line that fell off it looks like a vent line from the motor that lays on top of trans where does it go

[mottrhed]

there is a tube on top of the trans that it goes to, the other end goes to a plug up in the engine bay iirc.

if its like a 1/8" line or something small like that, it goes to the top of the tranny line, it's a vent line like mottrhed said. it has a check valve like thing on it, it doesnt have to go straight up to the engine bay, you can put it anywhere as long as it doesnt suck in dirt. the GM dealers had mine just hanging when they pulled my tranny so i tie wrapped it out the way.

I had a leftover vent hose when i swapped my trans and there's actually a few others that have had the same...
