I notice that you have some rather serious looking fasteners going all the way though the transmission and frame tube. I would suggest making those fasteners smaller. Graded 1/4-20 bolts will be plenty strong enough, even graded 10-24 fasteners would work fine.

I would also suggest having either an insert in the frame tube to transmit clamping loads from the bolt, or have a clearance hole on the outside tube wall and have the bolt only clamp to the inside tube wall. Otherwise it becomes easy to bend or crush the tube with zealous tightening.
