Hi,
I have a 1966 mustang w/ 289 2 barrel, auto transmission , We just started having a problem we the car not shifting into 2nd gear when starting out, is there a vacumn hose on these tranny that could have come off? If so where do I start looking?
Thanks Patrick

Patrick; Yes. There is a vacuum hose that runs from the intake manifold to the vacuum modulator that is mounted at the rear of the transmission. If you pull the vacuum line off of the modulator and there is fluid present, the modulator needs to be replaced. Very easy. Just watch for the small rod that may come out with the modulator. Be sure to put it back in.

I wouldn't expect it to stay that way. As Loren pointed out, your going to have to replace the valve.

LOL...My wife always reminds me of that. Hey, it took me 57 years to grow this belly!
Thanks for taking the time to reply. Glad to hear you got 'er. If that vacuum line had any fluid present or felt kinda
'mushy', you'll end up having to replace the modulator. But, all it takes is a backfire to blow vacuum lines off.
Good luck and have a great week.

I misread his response. I thought he said he pulled it off and put it back on. If you found it with the line off, then your probably fixed.
