Locate vacuum modulator chevy trailblazor 2003


Please verify the year of your truck. A 2003 Chevy Trailblazer has a 4L60E transmission. This transmission does not have a vacuum modulator valve. The 4L60 uses a vacuum modulator valve but the last year for that transmission was 1992. The perpose of the modulating valve is to control/regulate line pressure. The line pressure in a 4L60E is computer controlled or controlled electrically.

I need to change the transmission modulator valve on a 2003 Chevy Impala. I need help with the location of the valve and even steps on how to change it. Thanks


Hello, the 2003 impala's dont have a transmission modulator valve. this transmission is electronic controlled by the power train control module. the transmission uses a pressure control sol. inside the transmission instead of a vac. operated modulator valve. if you are having a late harsh shifting problem, this would be more in the area of a pressure control sol. at fault

The transmission won't shift out of 3rd and will only go up to 50 mph at around 3500 rpm.


check for a bad vacum to the modulator valve on your transmission,or a bad vacum to the modulator valve on the transmission. the modulator valve to the trans. works off of vacum from the engine,look for loose or disconnected vacum lines around the carb. or the air induction system. look for cracked vacum lines that seem to be sucking air when engine running at idle speed. in park. the modulator valve [usually] located on the drivers side,of the transmission,is the main cause of shifting failure. if the valve itself is bad, it will need replacement. thank you for choosing fixya.com!

1995 Saturn automatic trans. shifting hard enough to brake motor mounts. Any suggestions for fixing


you may need to change the modulator valve on transmission and also check the modulator valve to be sure it's getting the proper vacum to it. the modulator valve controls shifting in the transmission. also suggest lucas transmission treatment be added to transmission fluid, it frees up stuck valves in transmission. hope this helps!!!

Shifting problem,does not shift to drive


the modulator valve on the transmission may have gone bad, does it slip while driving or just simply won't shift easily? if you have to shift it manually from 1st to2nd to drive and it does fine it is a bad modulator valve on transmission or bad vacum to the modulator valve. hope this helps!!

Transmission does not shift out of 1st gear automatically. must get off gas for rpms to drop and then it will shift to 2nd gear. no other shifting issues.


There is a vacuum line that is connected to a vacuum modulator on the transmission. The vacuum modulator looks like a tiny inline fuel filter on the right rear of the transmission. Remove the vacuum line from the modulator, if transmission fluid spills out when the rubber hose is removed the modulator is punctured. The engine will **** your transmission fluid through the vacuum line and into the intake system and burn it through combustion. If the modulator is punctured you must have it replaced.
