They use a TV cable (Thottle Valve cable) to determine shifting.The TV cable hooks up to the carburetor or injection body linkage -in a (visual way) similar to the older (kickdown) linkages of 3spd automatic transmissions. It is NOT a Kickdown cable.
Proper adjustment IS CRITICAL to the survival of your 700r4.
you. Good luck
assuming your talking about the transmission modulator...visually inspect the transmission and look for a vacuum hose from the engine to the tranny...
No. You can remove the engine and leave the transmission in the vehicle.
engine vacuum or direct into the intake.
I'm not a mechanic / technician but I believe it can if the automatic transmission uses a modulator valve that has a vacuum line connected to it because the vacuum comes from the engine . If there is a problem with the modulator valve then the transmission fluid could be sucked into the engine
If your transmission has a vaccume shift modulator, the Engine will suck the transmission fluid out & sometimes if the modulator is real BAD U will have smoke coming out of the exhaust pipe. If this is an automatic, and the car is blowing some white smoke, the diaphragm in the transmission modulator is bad. If this is the case, you will have to replace the whole modulator.
The 1997 Chevrolet blazer modulator valve is located on the firewall in the engine compartment. The valve will be on the passenger side of the firewall.
3.73 if you have a 350good engine and automatic transmission
The automatic transmission fluid temperature sensor on a 1997 Chevy Blazer S10 is located on top of the transfer case. It is in the engine compartment.
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
I'm not a mechanic / technician but I have read that if the vacuum modulator on your automatic transmission is bad than fluid out of the automatic transmission can be sucked into the engine
Assuming you have an automatic transmission the dipstick is located under the hood on the passenger side in back of the engine, close to the firewall.
There are 6 bolts that hold the trans. to the engine block.
check for a failed vacuum modulator or a vacuum leak to the vacuum modulator. It sounds like you are shifting on the governor or engine management unit.
If the transmission modulator valve is vacuum operated and it goes bad it can allow the engine to suck transmission fluid thru the engine causing the engine to blow blue smoke out the exhaust.
That transmission is COMPUTER CONTROLLED and does NOT have a modulator valve. If you are having transmission problems then you need to have the transmission scanned with an OBDII engine scanner to see what is going on.
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
The vacuum modulator is on the front of the transmission. The modulator is a round valve and should have a steel line running from the top of the engine(next to the throttle body) down to the valve.
The Vacuum line for an automatic transmission runs from the modulator valve on the rear of the transmission to a vacuum port on the intake of the engine. Any available port will do as long as it is on the intake, not the carburetor if so equipped.
That would be the 4L60E transmission.
On some of the older vehicles the vacuum modulator controlled the shift points of the transmission by using the vacuum supplied from the engine.
I'm not a mechanic / technician but I read once that the modulator valve for the automatic transmission has a vacuum line connected from the valve to the engine and that transmission fluid can be sucked into the engine if something goes wrong with the valve
Possibly, but you haven't said which engine or trans.
it should be on the side of the transmission with a black rubber tube from the engine leading to it
Yes, but you have to remove the automatic transmission housing, and you have to replace the Torque Converter with a standard transmission clutch that matches the type of transmission with which you are mating the engine.
Yes, this really can happen. The transmission modulator ruptures and vacuum system system draws out trans fluid into engine oil thru vacuum pump into engine crankcase. Been there, done that. I replaced the modulator valve and dropped engine oil.
