Does any one Know what the Part number would be for a Bypass Valve to fit to my 4l65E which has the TransGo Modulator already fitted, as I want to Fit a Lysholm Blower, but I realize this will affect the Vacum required for the aftermarket Modulator,

Thanks in advance Tonner

 

If your running boost, you will also need to order the Pressure Bypass Valve, TransGo P/N "VBP-Vac"

 

Thanks Team.
