My search for a shorty D100 is over

Upon closer inspection this entire debacle could possibly be my own damn fault. Or maybe the fault of the guy building the converters, we’ll see. Looking at the converter, the pads for bolting to the flexplate are very shallow. Like 3/16”. The bolts I’m using are 1/2”. The thickness of the flexplate is like 1/16”. All of the bolts punched through the converter and hit the clutch. I think the pads are wrong. When bolting it up in the truck, the converter has to pull forward like 3/4” . The 904 converter I have here has HUGE pads compared to this one. If anyone knows the dimensions of the bolt pads on a 46re converter please chime in. I’ll know more tomorrow hopefully.

Last pic is a 904 converter.

The last thing that engages when installing the converter is the pump lugs, I think. Maybe if the pads are too thin the converter pulled out too much and disengaged the pump lugs. That would explain the loss of forward and reverse at the same time, if the filter was not just plugged with debris. Hard to say without measuring. Ask your converter guy how much "pull out" there should be for connecting to the flex plate. There is a spec But I do not know it. I have another 46RH still bolted to an engine but cannot access it for a while to check that.

I just checked a 46RH I have here. The bolts are about .420" long from under the head. The pads on the converter are about .280" thick as measured from the body of the converter. The depth of the holes is actually about .410" when I plunge the caliper into the hole until bottoms out.

I will try to double check these numbers later after I move stuff around for better access because the thickness and depth don't seam to play well together.
