    Sorry about the first answer i had submitted. I didn't pay attention to the complaint good enough the first time around. It sounds to me like you could have an internal problem such as a broken sun shell which is real common in that transmission. Could also be that your forward clutches are burned up.

The 1988 K2500 does not use a vacuum modulator. You only have a throttle valve cable (TV cable) wich is located on the left side of the transmission. the cable goes to the throttle linkage. If incorrectly adjusted or broken the transmission wont shift up/ skid.

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 REMOVE THE EGR VALVE


The Exhaust Gas Recirculation valve does just what the name implies: it diverts some exhau st gases back into the intake system at low engine speeds. This lowers combustion temperature to reduce NOx levels. It also reduces throttle response and bottom-end power.
Disabling the EGR valve is easy. Locate the valve and the EGR vacuum modulator valve (two gold-colored metal stampings, usually at the rear of the engine). The EGR valve has steel lines leading to it from the exhaust manifold. The EGR vacuum modulator has two vacuum lines between it and the intake manifold and a third vacuum (soft) line between the modulator and the EGR valve itself.
EGR Vacuum Modulator
EGR valve (arrow) is shown adjacent tosimilar EGR vacuum modulator valve. EGR valve is connected to exhaust manifold with steel lines. Modulator has vacuum lines only.
Disconnect the vacuum line between the valve and modulator and place any solid object of appropriate size (dowel, etc.) in the line, then reconnect the line. Or you can get a EGR block off plate

87 buick century won't shift out of first


The first thing is to check the transmission fluid level, then check the vacuum modulator located out on the side of the transmission, and be certain that the vacuum line is connected to the vacuum modulator, and that the vacuum line also has no leaks and it is connected to an intake manifold vacuum source. If you remove the vacuum line from the vacuum modulator and if there is any transmission fluid is in the vacuum line then the vacuum modulator is faulty and it will need to be replaced.
