The best way to repair a vacuum hose on your Chevrolet is to replace the vacuum hose. The vacuum hose is held in place with a retaining clamp on each end of the hose.

Check your vacuum hose.
There is no transmission vacuum hose. That is a vent hose.
You look up the size of the hose from the instructors manual that came with the vacuum you purchased. Then you look for stores near you which have the hose your vacuum needs and then you buy the vacuum hose.
