06 H3 and 4 low lock

[cnynctry]

I've left it in first gear only and the RPMs have to get high before the truck even moves then all of a sudden it catches. This is all from a dead stop in neutral, then pressing the buttons to go to 4 H lock then to 4 L lock, then to first gear. Even if once it gets going and I stop again and step on the gas it will do the same thing. (all this in our loose gravel driveway)

It acts like the fluid is low and it has to build up enough pressure before it will move the truck. I'll admit my wife always drives it so she never uses the lower gear options. I just do it every couple of months to make sure it still works when and found this issue. I know 4 low lock is a very low gear but the truck should move when you press on the gas and not have to wait till it spools up.

Just looking for something to tell the dealer when I take it in. Always helps when you can tell them what to fix. This may just be something new.
