I searched but got nothing. The 4.3L engine oil pan mounting to transmission has 3 lower bolt holes the transmission has 2 lower bolt holes. Would GM mount a 4L60 with 2 lower bolts to the 4.3L?

GMT-800 trucks the 4L60e works with both the 4.3 and the Gen III V8 (4.8, 5.3, 6.0). The V8 block has an non drilled and tapped transmission bolt hole (upper right) that can't be used. The 4.3 block has that mounting bolt drilled and tapped.

Picture is worth 1000 words. That hole hanging out there just looks weird for stock.
