So yesterday, I got my new badass 700r4 in my 89 suburban, bolted up, TC cable, cooler lines, torque converter, lockup harness, all of it. So I put a jack under the trans with a block of wood and lifted the tail up so I could put my crossmember in.. I discover it will hit the deep pan on the transmission!! First thought, being who I am, I say to myself, no problem, I'll just notch. The cross member, so I get a marker, and begin marking where I'll cut.... Then I notice... The frame has a second set of holes roughly 8" away from where I pulled the x crossmember, also, somehow it slipped my attention, so does the transmission (tailshaft housing), By moving it down that 8" the x member will clear the pan. Not a problem. But then the weight is being applied to the tailshaft housing rather than previously on the body of the transmission right after the pan. My questions are = 1. Why is there a second set of holes in the frame? It's a 2wd, I'd understand if it was 4x4 because the crossmember is then attached to the t case adapter , kinda makes sense? Not really, because a 2wd frame is diff than a 4x4.so what gives? 2. Will this be safe to do? I realize from an engineering standpoint, the weight of the trans is supported at the motor, and then the four 3/8 bolts on the tail housing would have to sheer off, but it just looks.... "off" to me. Tell me your thoughts. Thanks guys. I'll send pics of the holes in the frame later if someone wants to see.
