RE: Replacing the A4LD Vacuum Modulator
Later shifts, transmission fluid in the lines, and a wired burning smell (also bad shifts)

RE: Replacing the A4LD Vacuum Modulator
cool, just asking for later viewers of this thread. It should be put in the tech articles.

RE: Replacing the A4LD Vacuum Modulator
how much did it cost you for the new one? And where did you buy it at?

RE: Replacing the A4LD Vacuum Modulator
checked mine today and it was leaking badly. So i replaced it and figured i would change the filter and fluid in the tranny also. Well come to find out my trans is out of a 90 mustang even though my mustang is a 91. Drove nearly clear across town to the parts store that had the 91 filter to find out it didnt fit F*** me. Should have double checked.
Sleeper does your new one have an adjustment screw on it?

RE: Replacing the A4LD Vacuum Modulator
Yes it does, but thats because its the turbo one (highly recomend it since you can change your shift points with it
)
