Default 4L80E How much resistance turning drive shaft? (dynamic racing)

Noticed the car was crazy hard to push back and about twice as difficult as it should be to push backwards. We assumed this was a rear end issue. Unhooked the driveshaft and the rear turns just fine. Grabbing the DS by hand turning it FWD is about twice as difficult as it is on my glide which I figure is normal. But it’s damn near impossible to turn backwards. Like 5-6 times the effort? Does this sound “normal”?

This is their top of the line MVB 1500+hp deal. I sent an email to them as well just curious what anyone else has found.

-thanks

Sounds normal to me. They are always tight trying to turn one way as you are trying to turn most of the gear train inside the box through the sprags

It's normal as long as it will move. I thought I had issues too but found out that's the way they are.
