1995 Ford Taurus Question: Vacuum leak and transmission
I still have not found the vacuum leak. Is there a vacuum line to the transmission or would vacuum cause the transmission to shift differently? Would the vacuum leak cause the automatic transmission to shift hard. When putting it in drive, the car jerks forward, it also jerks hard from 1st into 2nd gear. I don't want to put a used transmissiom in and still have same problem. Thank You in advance for your answer! - Visitor
No and No -- No vacuum line to this transmission. The transmission is electronically operated and controlled. A vacuum leak will cause the engine performance to suffer, causing possible load and throttle position issues, which could indirectly affect transmission shifting. But that's kind of a stretch, really. What is telling you that you have a vacuum leak? Is your transmission full will clean fluid? - DaveJHM
