Question about hesitation with Tranny

[stever1986]

Ok i try and make this simple. When I go up hills from a slow speed , I notice that the truck feels like it is hesitating to get up the hill under light load. If I give it more gas then it drops a gear and shoots right up. But if it is a light gas i can watch the tach bounce slightly as it increases until about 2200 and it smooths out... Normal?

If you came from a 4 speed truck before it will take some time to get used to how a 6 speed functions. But yes, this is normal. Gotta get into the gas a little more on these trucks to get into a lower gear to go up grade.

came from a 4 speed Chevy Impala SS. This is my first truck and also first 6 speed. I have driven many chevy express vans but none with a 6 speed. Just seems like it struggles but then again if this is normal, I will live with it.

my 2012 Express at work will do the same thing. i find that i will use M5 more often on lite grades than anything else. 3.42 gears, double over drive trans sucks on any little grade..

There is a big recall on the new truck transmissions, announced over the weekend.

Recall is on transfer case... it doesn't resolve the "normal" described here.
