I bought a parts car for the tranny. Guy told me he was low on oil and the car just died. My question is i was checking out today and i removed a rod through the aluminum part of the oil pan. i was just wonderinf if something like this can cause harm to the transmission itself? I can run smoothly through all the gears and when in neutral the wheels spin freely. I checked the viscous coupling like the FSM outlines and it still works. Both wheels spinnin same direction.Als0 should note the car is all stock no Nitrous or any other nonsense. I am not sure if this an all motor question but i posted in the 4th gen forum and we all know what its like in there.

The only way your tranny would be hurt by this would be if the rod was actually thrown through the tranny itself....it should be fine.

 

Not entirely true. If the actual cause of breakage was a mis-shift from 3-2 instead of 3-4, then the engine may have hit 9-10k rpms or more. That means that the tranny also hit that rpm, which could damage it.

That being said, the tranny is very likely still good even if there was a misshift. I do doubt that he just ran low on oil though. I would think that would cause a piston to seize or similar, not rocket a rod through the block.

 

Well if a 1 piston ceased wouldn't the other 5 still moving then the rod that was attached to this piston couldn't move which the crank was still moving causing the rod to snap like it did?

I think the tranny is fine or worst case the clutch fried? any other thoughs

 

very true. That could be the cause as well.
