Thanks for jumping in Roy. It was hard for Dad to explain to me, and even harder to explain it to someone else. I searched around for an image of one installed in a powerglide, but this is as close as I could come. Some people call it the rooster comb.

Dad said that he tightens the band with a speed wrench. It should only take about 10-15 ft/lbs. of torque to tighten.(almost snug - not tight) Then back the adjuster off 2 - 2 1/2 turns and lock down the nut.

I'll call Dad again tonight to try to get a clearer explanation of how the rooster comb goes in right. It's my understanding that you can shift through the different ranges and watch the valve moving to each position to determine if it(the comb) is installed the right way. It can be installed just one or two notches off(on the shaft from the linkage), and cause such a problem I think.

I just found this on the old car manual project - thanks to Keith Hardy. thumbs_up thumbs_up
