4R70W/Dana 20 Need Help

[Nickm1024cobra]

Ok, so Im mocking up my drivetrain and finally have twin sticks mounted to my dana 20 t case. Heres my issue. No driveshafts installed.

With rear in High I can still turn the rear yoke freely no matter what gear the trans is in. This doesn't seem right. Essentially if I had no e-brake and left the truck in park it would roll away.

-With both in Low, and trans in park both yokes are locked up. Trans in any other gear I can turn the yokes with a prybar and it turns the motor.


Thoughts on why the rear yoke free spins when T case in High and trans in park?

Thanks!

A little research tells me
I might have put the input gear on backwards.

That doesn't sound right. Are you sure the transfer case is engaging when you put it in high? I just put an 4r70 in my Bronco with the dana 20. And when I put in the rear driveshaft I rotated it by putting the trans in neutral. And when I went to tighten the driveshaft, I put the trans in park with the transfer case in high. And it stopped the driveshaft from spinning.

It happens at least once per year on here. The good news is you will never make that mistake again.

I'm just excited I'm learning.
And I didn't have it filled with fluid!

Getting smarting by doing - the way to go! I love this board everyone is so helpful.

If you haven't already, add a drain plug to the trans pan.
