Good 4 speed tranny in a 1970 Z (4095), ran without oil. After 40 miles, she seized. Can it be rebuilt or is it history. Before the 'incident', it shifted smoothly, synchros were strong, all was well. Any thoughts?

Same thing happen to me,but i forgot to replace the oil cap

it took about 3 miles,thats when it start to make this weird

noise,but mine was still rebuildable even know it was knocking

i drive the z back home,but i would say in your case i would

get another engine i think its cheaper than rebuild.

Read it again......he's taking about his transmission not his engine.

Mike, it depends. Not a definitive answer, I know. But it depends of what parts were damaged. If the damage was confined to just the bearings, it may be salvageable. But if the bearings spun on the shafts, or spun in the case, I'd consider it a lost cause.

In any case, it will need to be disassembled to know for certain. Drop it by my place next time you come to Oregon and after a week or so I can tell you for certain.
