Other way around, it pushes easier forward.

Forward is much easier than backwards on mine.

The rear sprag holds the rear drum from spinning in first gear only. after the trans shifts to second the drum spins in the opposite direction and the only friction loss would be from the drag of the fluid that is in between the rollers and races.
Does it cost ET ???
I could come up with a silly idea to make it a non issue, but you'd have an explosion waiting to happen, so I won't.

i had the rear support galled up in my trans, it was to the point where i couldn't move the car at all trying to push it. I put in a roller rear support in its place

Here's a personal experience condition You can check: Put the car up on jackstands and remove driveline. Rotate pinion and check for ease of rotation both directions. Next pull axles out of pumpkin and notice if on subsequent reinstallation the bearings slide easy or align with the bearing flanges. My 9" axle bearing plates had moved from all the abuse of racing and were contributing to the gawd awful condition of "this '!#$#$234ng' thing is too hard to push!". Noticed car slowing down as well so it might not be the transmission. Something else to check. 
Drive shaft was disconnected and he was turning the
diff yoke then the drive shaft(the rear end was fine)

Again, depends on which way you're trying to turn the disconnected DS; looking from from the rear, it should turn easier in the counterclockwise direction than in the clockwise direction. If it turns equally hard in both directions it might be worth worrying about.

Of course it does. Anything that makes the car hard to roll, takes power to overcome that drag.

My car also rolls really hard. Ever since I built the car it has seemed really hard to push, like impossible by myself. I know when I try turning and rolling the spool binds up but even straight it rolls really hard.

I have a full width 8 3/4 in the car. If it is bent it was like that from the day I bought it cause it has been like that. I will be pulling it apart in the next couple weeks I will have to check it out.

Does it have a back brace... the OP the drive shaft
was disconnected and the rear rolled fine... a simple
way to check the diff is to pull both axles.. if they
pull out and slide back in easy the tubes arent bent
enough to worry about YET... but ANY car that hooks
CAN bend the tubes and they WILL be bent forward

On a Torqueflight.....No, pretty much is what it is. You could go the super lightweight internals route and all roller bearing, which will help, but a 3 speed Chrysler trans has significant drag.
On guys talking about the car pushing VERY hard.....the reason is, your rear housing is bent. Because it is factory does NOT mean it isn't bent.......as a matter of fact, that pretty much guarantees that it IS bent. Never, repeat NEVER seen a factory housing that was anywhere near straight enough for a race car application. And if you have an 8.75 under something with just average power and it hooks..........you better have significant bracing on the housing, because it WILL bend very easily

If it turns hard or easy both ways take the tranny apart and look at the rear spraque 
I ended up using two carpenter squares and measured out 15 inches from the center of the axles off of the axles flanges,no brake drums on the axles, front to back and then top to bottom 
There on there square now 
Do the basic measureing and go from there
