B&M 20234 Adjustable Vacuum Modulator

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

Exactly as described. Fit perfect and installed easy.

Works as it should.. Great job

easy install

Worked great....

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.

great item fo the price, than you.

My TH400 in my classic Jeep was shifting to early. I replaced this and used the screw to adjust this shift point to get the later shift I was desiring. Worked perfectly.
