I drove a truck with a chain holding the rear of the transmission. The owner said the bolts had pulled out of the clutch housing.
I saw another rig on the shoulder beyond a rough railroad crossing. The transmission was on the ground. -
That spot would be so that you can put a transmission cooler on there. On almost every truck I have worked on/driven there has been no transmission crossmember. Now on some Volvos and Western Stars they have the the rear engine mounts on the front of the transmission.

No, you do not need the rear support. Your truck was built without them. If you needed the rear support there will also be brackets bolted to the frames for the support, or (bungee spring) to rest on. You would also have an 18 speed trans. Yes, the whole trans is supported by the bell housing bolts. Any one who has had the bolts come out are the ones who had the tranny out at one point and reinstalled without the mechanic cleaning the threads and not properly installing them.
BryRylanKW and Les2 Thank this. -
should I at least check if there tight? I spent the last few night replacing cross member bolts on the rest of the frame that because loose and spun....
