B&M 20234 Adjustable Vacuum Modulator

easy installation, works great

Through this in a used transmission and works fine so far. Bought this one for the name behind it.

Worked great....

easy install

Excellent product. Brought back to life my 87 Jag XJS

I bought this to replace a leaky modulator on my 1976 GMC motorhome with a THM425 and 455ci Toronado engine. The shift points were perfect out of the box, no adjustments needed.

Fit perfect and works awesome to firm up the shifts on my 1975 jeep wagoneer with a th400 transmission. The factory setting on this is really close to what I️ wanted but I️ took it in two more turns to get it to hold the gears for a bit longer. Very, very happy with it.

It worked as advertised.
