Hey all, hope it's okay to get right into why I'm here..

I have a 2008 silverado wt

I'm throwing a p0787. Both solenoids should be good now. Noticed a hose connecting to the top of the transmission and split with a Y fitting running forward to nowhere and the other end backward to nowhere.

I had been leaking transmission fluid slowly, so filled it with sealer, only to discover that when the truck is running, it drips out of the end of the hose. So it's only reasonable to assume that these open hoses leading into the transmission chassis are likely causing a pressure loss and therefor a voltage drop.

Curios what it is. If I\m off base. Why is there even a hose on the top of the transmission at all, like what's its purpose? The fluid cooling lines are hard piped and running to the radiator, so I'm at a loss. If someone could help educate me it'd be hugely appreciated. Google searching isn't working.

 

My bad just saw the forum heading..

 

Vent hose??

 

Welcome to the forum. Hopefully you found your way over to the Silverado section of the forum. You will get more views over there.

 

I did thank you!

It does appear to be a vent hose for anyone wandering this page and as clueless as i am lol

thx

 

Vent tubes was my first thought also but wondering why you would getting transmission fluid coming out of them.
