Hello anderson31...the transmission modulator for the V6 front wheel drive should be front on the power pack, to the right of the engine above the starter. You can follow the vacuum line from the manifold down the front right of the engine to the modulator...
Removing the air induction will allow for easier access...
For safety...disconnect neg. battery cable to prevent suprises... u'll be in tight quarters.
Good Luck...hope this will fixya up.

Standing at the front of the car there is a metal line that comes off the intake manifold going toward the driver side. follow the line down the transmission and it connects directly to the modulator.

My 1994 buick regal gran sport jumps a lot when at a stop sign or red light, but when i accelerate the problem goes away. also when in park my RPM's drops extremely low and it sounds as if its goi


This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

How do you install a vacuum modulator in a 94 regal


Remove the vacuum line at the modulator. Remove the bolt and the modulator assembly retainer. Remove the modulator assembly. Reverse order to install.

NOTE: if the modulator valve comes out of the bore when removing the modulator vacuum assembly, note the orientation of the valve and reinstall it in the bore before installing the new vacuum modulator assembly. (see picture)

I need to change the ECP soleniod in my 1999 buick Regal.. Can I do this without taking the transmission out?? Thanks...Kent


Yes, you can remove the bottom pan and replace the valve assembly! It works as a pressure regulator This replaced the throttle pressure valve, and the vacumn modulater on the older models.
