Moving on from starters to transmissions I now see I have a broken band. I have a Hughes valve body full manual reverse pattern with transbrake. I'm taking the valve body down for a bench test. I think the servo piston stuck. I may just replace the piston. So an R servo does that refer to the piston ? I will look to see if I have the E lever. Hughes says Kevlar band I have heard other people say no Kevlar. What's the opinion ?
