Vacuum modulator ??

[sevensixoh]

kinda new with transmission stuff:

Ive been having problems with the powerglide tranny and was about to rebuild it , so I got under there and saw that a hose was broken off what I think is the vacuum modulator . Could this hose possibly be causing my tranny problems ? please any help would be great !! thanks

if memory serves, that will result in hard shifting, at least. It may also cause the engine to exhibit signs of a vacum leak. Why not hook it back up and see if it helps?

the hose is corroded through , ill try and replace it after work today .
Hopefully this will fix my problem , I really dont have the funds for a rebuild at this time !! thanks
