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.

rear pass side of trans. vacuum modulator with vacuum hose attached to end. unplug hose and remove retaining bolt and retainer clip. gently pull modulator out of trans without dropping push-pin. have new one ready. while holding finger over hole to prevent trans fluid leaking place pin in new modulator and install. make sure vacuum hose is attached and in good condition on engine end too. if trans doesn't shift still go for the governor. located under a round cover w/a bail clip on the drivers side of trans just behind shift linkage. use screwdriver to pop off cover and governor just pulls out. nylon gear on shaft likely worn out. hope this helps. jp

It is on the passenger side of the transmission towards the back of it. It will have a vacuum hose hooked to it. There will be a small bracket with 1 bolt that holds it in the transmission.

Why does a 1990 Ford Festiva automatic transmission not shift into third gear?

Most likely a bad vacuum modulator or no or little vacuum reaching the modulator. Check to see if there is any vacuum going to the "can looking thing" on top of the trans. It may also be a broken or misadjusted T.V. cable going from the throttle valve to the trans. (if it has one i cant remember) Take it to an actual TRANSMISSION mechanic they cost more per hour but less likely to hear the all too common "it needs a new trans".
