Hi All,
I was going to replace my Transmission Vacuum Modulator today.I put a Vacuum
Gauge on the hose going to the old Modulator .
I Started the Engine to to get the excess Fluid, back in the Torque
Converter.I checked the vacuum Gauge and it read 0 Vacuum at Idle.I checked
the Vacuum line and it was clear.I checked where the line was hooked and it
was ported Vacuum .
I checked the emission Chapter in my Manual it did not show a hook up to the
Vacuum Modulator.
I checked the Transmission chapter it did not show a hook up either
My Transmission seemed to Shift normally, but this last Summer on two
occasions it didn't want to shift to high Gear..I backed off on the Throttle
and it shifted to High Gear.
Which Vacuum ,should the Modulator, be hooked to.?
