transmission movement under load?

All,

 

From searching till I'm lost, I know that the pinion end of the diff wants to raise up under heavy throttle/load, and that its good to limit this motion to maintain good u joint angles.

 

What does the output end of the trans want to do under load? I'm guessing it wants to raise up also, because of the posts I've read about tearing the rubber trans mounts and the poly mounts being able to resist this better.

 

Am I correct in this thinking? Both diff and trans want to raise up under load? If so, does the poly trans mount prevent the trans from lifting, or is it good to fit some kind of restraint on the end of the trans as well?

 

Thanks

 

Bill

The transmission is bolted to the engine so it twists parallel to the chassis centerline. The diff is unique in that its changing motion 90 degrees so the twisting torque becomes perpendicular to the chassis centerline.
