B&M 20234 Adjustable Vacuum Modulator

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.

Exactly as described. Fit perfect and installed easy.

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

went in like OEM and worked great for my shifting issue

Worked great....

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

Great product
