B&M 20234 Adjustable Vacuum Modulator

went in like OEM and worked great for my shifting issue

Worked great....

Exactly as described. Fit perfect and installed easy.

Works as it should.. Great job

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.

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

easy install

Easy to adjust and let me set the shifting where I wanted it

excelent i put it in a TH350 and have no problems
