Hello. My car just started SLAMMING gears lately, so I knew it was a vacuum leak of some sorts.
I got out my mityvac and pulled vacuum on all the lines coming from the vacuum pump. I pulled vacuum on the line going to the vacuum control valve, it was leaking slow. I pulled the line going directly to the tranny, it held vacuum fine. I pulled a vacuum on the control valve itself (with the other ports blocked off), and it was leaking slowly.
Is this my problem? The vacuum control valve? Im assuming it should hold a steady vacuum. I just want to make sure before I order a new one.
thanks
