Hello my name is Doug and I have a small problem I need help with. I have a 1994 Mazda B4000 four wheel drive. the transmission gave up and I'm going to replace it . the problem is when I pulled my transmission out and went and got another replacement ,the replacement has a vacuum modulator the one I took out of the truck does not have a vacuum modulator will this new transmission with the vacuum modulator go in this truck without modifications and work?
