Driving that vehicle will lead to serious transmission problems in time. Have the Transmission Fluid flushed and filter changed soon. Next time stop by your local auto parts store and ask for assistance.
Transmission modulator valve is bad.
Flow valve for what? Coolant, transmission fluid, fuel, what? You need to be more specific.
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
if youre referring to the bleeder valve, its on the clutch slave cylinder bolted to the transmission
To the left of the Transmission Fluid stick. It on a little "T" valve.
Does it have a dipstick?
Located on the valve body inside the transmission.
There is no dipstick for the transmission. It has a check valve on the side of the pan.
If a vacuum modulator has fluid in the vacuum port, it has failed and should be replaced.
The valve body of a transmission is a complex component of fluid paths, sensors, and solenoids that are crucial the shifting and function of the unit. The valve body is the assembly directly accessibly upon removal of the transmission fluid plan. The replacement valve body for the 2000 Dodge Grand Caravan with the 3.8L engine and 41TE automatic transmission is Pioneer part #765024.
on some cars there is a automatic transmission modulator valve that tell by vacuum when to shift gears. If that valve goes bad you will get tranny fluid in your lines.
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
