I'm hearing a loud hissing noise coming from transmission…

Customer Question
I'm hearing a loud...

I'm hearing a loud hissing noise coming from transmission area . The noise increases with acceleration and the truck is not shifting at proper shift points (revs up to high ) also the motor is accelerating , but the vehicle isn't going any faster. when I back off the gas it engages and it will run better down the road ,but it surges. I found a loose rubber hose line at the top part of transmission but have no idea where it goes to

Mechanic's Assistant: Have you heard this particular sound before?

Not till recently when I GAVE IT GAS but it has increased tremendously

Mechanic's Assistant: What is the model/year of your Chevy?

1997 chev s-10 pick up w/ 4-3 L V-6 VORTEC AUTO TRANS

Mechanic's Assistant: Are you fixing your S10 yourself? What have you tried so far?

Was going to try to fix myself ,my service engine light is on. checked fluid levels already. I'm thinking that hose is vacuum to trans ?

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I THINK THAT'S ABOUT IT
