C6 trouble?

[stm]

Hi, all.

I have anothe strange global question...

One day i drove to off-road and saw it: when my Bronc goes up to soft cover hill with more than 45 degrees grade (sand hill for example) - it's stops on the slope, when it reaches max angle. All wheels don't spin in this situation and no slip!!! Tranny stay in D position, 2H or 4H in transfer case, engine at 1500-3000 rpm - but car not move and all wheels not spin!!! Where is torque? Tranny is stall?

How car should behave in this situation?

When i put transfer case in Lo position - all is ok. Wheells starting to "dig sand", "mighty and powerfully".

And i don't want make stall-test tranny for my concerns to **** the old tranny...

It can be observed only in hard angled slopes.

Tranny is C6 and engine is EFI 5.0.

It just sounds like the grade is too steep for the engine and tranny to pull. 4whLo would be the correct gearing for that steep of grade

Yes, it's so steep, i agree. But i think, that if it's so hi and steep - torque power must slip the wheels. Car can't move -> it must slip wheels... Sand is not good pave for good grip (traction). M-m-m, or i was wrong?

And second - if car can't move for hi slope and suppose, slope have a exellent pave whith good grip (with no slip on it) - what happens with a car? ATF will circulate in tranny, while it not overheating?

when off roading use 4 low, thats what its for. if your engine wasn't free reving then your trans is functioning properly.
