yes.. there are probably 5 differant modulators for that transmission. they are all color coded and must get the correct color.
Transmission modulator valve is bad.
You don't mention the year , so I'm wondering if your engine oil level is going up ? I'm not a mechanic / technician but I've heard that a bad transmission modulator valve can suck transmission fluid through the modulator vacuum line so it goes into the engine
If it is an suto trans and has a modulator, the oil could be going through the modulator and burned. Pull the vacuum line off of the modulator and see if there is fluid inside of it. If so replace it.
I'm not a mechanic / technician but is your engine oil level going up I've heard that the modulator valve on the passenger side of the automatic transmission ( behind a heat shield ) can allow the transmission fluid to be sucked into the engine through the vacuum line if there is a problem with the modulator valve on Ford Explorers up to the 1994 model
On the passenger side, toward the rear of the transmission, up on the side, with a vacuum tube running to it. Unplug the hose, remove the bolt holding the retaining fork,slide the modulator out. Modulators are color coded, so you will need your modulator to match up to the new one. Need more help contact me through my board and I will try to help.
Raise the car and support it in a safe enough manner that you can go underneath it without it falling on you -- this means jack stands, ramps, or a car hoist. Remove the vacuum line from the modulator. Put a drain pan under the modulator and remove the bolt that holds the clamp holding the modulator into the transmission case -- most likely it's a turbo 350 so the modulator will be in the back on the passenger side and the clamp should have one bolt going through it that is removed with a 1/2" socket. With the clamp removed pull the modulator straight out -- you're going to lose some fluid when you pull the modulator out. Make sure the rubber o-ring seal comes out with the modulator. Make sure a new o-ring is on the new modulator and put it in the case, then install the clamp & bolt and tighten it. Re-connect the vacuum line, lower the car and start the engine, on level ground check and refill the transmission fluid as needed and check for leaks. If no leaks you're done and ready to test drive.
I assume it is the same for my 96 Impreza, but when I changed mine, I poured it in where the transmission dipstick was through a funnel
Through the transmission dipstick where you also check your levels. You will need a small funnel that can be purchased at your local auto parts store.
probably sucking transmission fluid through a broken diaphragm on transmission modulator. look for a vaccuum hose going from carburetor or throttle body area down to an external pod like device mounted on the transmission.
Because the output circuits of the modulator would otherwise present an impedance to the RF amplifier in parallel with the transmission line and antenna system, which you don't want. In other words, you want the RF all going up the tower, not down to ground through the modulator.
In a 2005 Dodge Neon, the battery connects to the modulator through the wiring harness. The modulator is typically located near the transmission and is connected via a series of electrical connectors. You may need to consult the vehicle’s service manual for specific wiring diagrams to locate the exact connection points. Always ensure the battery is disconnected before working on electrical components to avoid shorts or damage.
An FSK Modulator is much the same as a GFSK Modulator ,but GFSK uses a Gaussian filter as well. In a GFSK modulator everything is the same as a FSK modulator except that before the baseband pulses (-1, 1) go into the FSK modulator, it is passed through a gaussian filter to make the pulse smoother so to limit its spectral width.
