Q: Transmission vacuum modulator on 1996 Ford Taurus

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The car jerks when going into 2nd gear and just revs when trying to reach 3rd gear. Is this due to the vacuum modulator and where is this located?

does not have one. it is electronically controlled. you have had an internal failure and the unit needs to come out and re built. sorry for the bad news.
