Where is the vacuum modulator on a 93 Chevy truck?

That transmission is electronic controlled. No need for a modulator valve.


Does the transmission have a modulator valve?

as far as I understand , it does not have a modulator. e4od are electronic. no vacuum shift modulator


What is a TRIODE and what are its uses?

A triode is a vacuum-tube (US) aka valve(UK) with three electrodes : an anode, a cathode and a grid. The cathode is heated electrically which boils off a cloud of electrons. The anode is made positive ( typ. 100-500V) which attracts the electrons towards it. The grid is an open structure, usually of thin wires, placed between the anode and cathode, but nearer the cathode. If a negative voltage is applied to the grid the current flow through the tube is reduced. The more negative, the less current. Prior to the development of transistors, tubes were used for all things in radio,TV and electronics. Different tubes had different numbers of electrodes; the triode was particularly suited to high power amplifiers, especially at radio frequencies. Triodes are still used today by shortwave radio stations, and for RF heating equipment.


What is triode valve?

A triode valve is a three-electrode electronic device. It can amplify, oscillate or act a a switch. Most commonly, its three electrodes are contained in a completely-evacuated envelope (a near-perfect vacuum). The envelope may be of glass, ceramic or a metal-glass or metal-ceramic construction. Most commonly, the electrons needed for operation are produced by a heated filament or cathode. It is possible to do without the filament/cathode, but such devices are uncommon. The heated filament/cathode defines this as a *thermionic* triode. Some triodes do not use a pure vacuum. Instead, they use low-pressure gas, or mercury vapour, to allow them to operate at higher currents and lower voltage drops than vacuum triodes.


What does a vacuum switching valve do?

The Vacuum switching valve controls the EGR Valve.


Where is the EGR valve in a 1993 Cultas Cierra?

If it is an electronic EGR valve it is on the top of the engine on the rear left or drivers side it has three solenoids and a wire harness at the top IF YOU HAVE THE V6 (3.3) ENGINE IT DOES NOT HAVE AN EGR VALVE. IF YOU HAVE THE 2.2 4 CYL YOU HAVE A VACUUM TYPE EGR LOCATED ON THE END OF THE HEAD ABOVE THE TRANS.


What is the 1994 gmc safari code 32?

the code # 32 is telling you that it`s a exhaust gas recirculation error. your electronic vacuum regulator valve controls EGR vacuum. what needed to be done is replace your EGR valve . the cost to replace this part is based on what type your vehicle needs . choices are electronic EGR valve at about $120.00 dollars if your vehicle has fuel injection. or $70.00 dollars if your vehicle has a carburator.

If your EGR valve is vacuum operated, simply remove the vacuum hose from the valve.
