Where is the Modulator?

[Rx7freak08]

I have a A4LD and I'm looking for the modulator that has the vaccum line on it.

Passenger side, under the heat shield, on the side of the tranny just above pan level.

Thanks Glacier

that being said more than likely you will want to get at it from the top under the plate where a stick shift would be if it were a stick shift remove both front seats and the plastic at the doors pull the carpet back into the rear passenger area then remove 4 screws that hold plate in youll need a short 10 MM combo wrench and no matter what dont lose that pin in the modulator

OH it is a automatic. But thanks anyway.

The automatic equipped versions of the Explorer have this access cover plate too. It was originally meant for the manual version.

Ok so if I need to get to the solenoids and the modulator would it be a good Idea to just take the valve body out and put the shift kit in it.

What kind of problems are you having with your transmission?

Like when it is cold it doesn't shift from 1st to 2nd. Only at like 4500 rpm's. Once it switches over to 2nd it stay there and when I stop and go it is still in 2nd. I had a problem a while ago where I came to a stop light and the transmission stopped on me and the engine died. We tried it over and over again to put it into gear but it wouldn't let me and the engine would die again. The engine never died in park or neutral. So we put it in neutral rolled it into a parking lot and let it sit there over night. The next morning my brother went to the car diconnected the battery and reconnected it and it shifted fine all the way home.

Now I want to clean my solenoids but it is to hard to get to. Also need to change the tranmission fluid out.

Did you check for transmission fluid at the modulator vacuum line under the hood?

The delayed shift from 1-2 sounds like the governor but could also be the modulator or a VB issue.

Have you tried to adjust your bands?

My transmission started malfunctioning by not shifting into OD and the converter not locking. Turned out I had a fair bit of shiny (sparkles) particles in my pan. They were causing the two solenoids problems. I now sport an external filter which should catch all that garbage and prevent any new issues with my rebuilt VB.

Snap a photo of the inside of your pan when you change the fluid.

Good luck

You been reading in the transmission forum? Lots of good info there...

The vacuum line is rubber from the modulator for a few inches then turns into metal tube. That tube goes up to in behind the upper intake where it turns back into rubber. Check it there.
