I am in the middle of my second 4l60e rebuild on my 2000 Silverado 1500 4x4. The first rebuild made it about 6 months before spinning the bushing in the pump cover and taking out the front seal. I am pretty sure I need a new pump cover, but I would like to measure the bushing hole to see how much oversized it is before I proceed. I've been searching all morning, but I cannot find any specs for this measurement... Does anyone know the spec, or know where I can find the spec? Thanks!
