Can someone give me the part # for the correct tranz vaccum
modulator? I've had my A4LD tranz all redone but I have a shifting issue. Turn the boost under 10 psi and the shifting is all good. But as soon as u turn the boost up near 15 psi or heavy acceleration. The thing either won't shift or u have to lift to make it shift. My guy builds all kinds of performance OD transmissions for newer cars and trucks, but this one has him scratching his head. I'm thinking I have the wrong modulator.

original ford number for a 1987-1988
e4sz-7a377-a or motorcraft # tm-70.
this is from the last microfiche ford issued, so the part numbers could have been superseded.
hope this helps.

Several parts houses have the modulator listed as "no longer available". Carquest lists the part under #57-7028 as a cross over to the Ford part number E4AZ-A.
If all else fails email this guy to see if he can help.
