Typically, you can find the transmission modulator valve near the rear of the transmission. Its function is to control and regulate pressure.
Well, isn't that a happy little question! The modulator valve on a 1994 Chevy 1500 pickup is typically located on the transmission. It helps regulate the transmission fluid pressure to ensure smooth gear shifts. Just remember, there are always friendly folks at auto shops who can help you find and take care of your modulator valve if you need a hand.
A 1993 Jeep does not have a transmission modulator.
Answer DIAGNOSE,whitr exhaust smokecould be either 1/ perforated diaphragm on the auto transmission MODULATOR VALVE. OR a LEAKING cylinder head gasket(or cracked cyl head) see IF using water if NOT then probably modulator valve
No. That transmission has a computer controlled electronic governor. If it is not shifting properly you need to start by checking PCM codes.
the 4t60-e transmission uses a shift modulator that can be found at most auto part stores. however i believe the '99 regals use the 4t65-e transmission which are not vacuum operated therefor to up the shift pressure you will need a tuner or a shift kit.
most overdrive transmissons no longer have modulator valves they are computer controlled.
Starting with the 1995 Ford Explorer the automatic transmissions are electronically controlled ( I'm not a mechanic / technician but as far as I know it doesn't have a modulator valve )
It is on the right/passenger side and at the rear of the auto tranny.
check vacum line to modulator, or replace modulator
what type of transmission? for 4L60E trans, try changing the A & B solenoid before giving up on ur current trans, these are located in the pan, they are black and sit side by side, a spring clip holds them in place. cost bout $50 AnswerIf it has a modulator valve gone bad - this will prevent it from shifting. Call Auto zone and ask if there is this type of valve for your transmission. Check the fluid level. Check for trouble codes with a scanner, Check shift linkage/vaccum lines.
the vacuum modulator on the transmission was allowing the fluid to be sucked into the intake manifold. what didn't burn went into the crankcase.
They are located internally in the transmission itself.
