C6 being dumb
I recently bought an '83 f-150 w/ a 302. I put in a new motor, but the tranny is acting up now. It shifts fine going into 2nd, but shifts back and forth between 2nd and 3rd for a second or two during normal driving. I pulled the vacuum hose off the modulator and there was a little fluid in it. Also, when the engine is running, I can hear a hissing sound (like a vacuum leak) around the modulator, but only in park and nuetral. Will replacing the modulator fix this?
