How do you change the vacuum modulator on 96 Ranger 4LV6 auto trans?

vacuum modulators are used on automatic transmissions to control line pressure relating to the way a shift feels when a transmission changes gears. Later models went to a fully electronic valvebody with line pressure controlled by the vehicles computer.If your question concerns a1996 Ford Ranger with an automatic transmission and a 4.0 liter V6 engine then the answer is--- you can't because this vehicle doesn't use a modulator for the transmission. If your asking about the modulator because the trans is shifting hard then you probably need to have the computer scanned to check for diagnostic trouble codes which would cause a condition called ''failsafe''. Line pressure is raised to protect the trans and to alert you to the fact that something is wrong. 4R44E-4R55E

More Info, If You Do Not Find A Modulator, You Could Have a Different Trans. If You Have A Square Pan With 16 Bolts Then You Have A 4L60 or TH700( no modulator on these) If the pan is oval and 17 Bolts Has 4L80 ( no modulator on these) Hope This Helps You Should Have A TH400 Trans & It Does Have A Modulator.

i would check the vacuum hose that goes to the vacuum modulator on the transmission the vacuum modulator probably has a hole in it and the fluid is going into the engine and being burned or check your coolant the radiator may have a hole in the transmission cooler inside the radiator so check your coolant and the vacuum hose for trans fluid good luck

When you get ready to run the vacuum line from the turbo 400 trans modulator to an Edlebrock Performer 800 CFM carb, attach the vacuum line for the transmission vacuum modulator to the bottom constant vacuum source or the plug that is below the throttle plate. After that, install the vacuum advance to the port that is signaled or right above the throttle plate. Once that is completed, install the large vacuum line to the back of the carb for the power brake.

Newer models like yours do not have a modulator on the trans; they are computer controlled. If you are having shifting problems I would suggest you change your trans fluid and filter; that should clear up shifting problems if it seems to stick in a lower gear. I hope this helps you. Mark
