Default Sluggish when in L2 gear

Last night done friends decided to take a ride in the woods behind his house. My Jimmy 4wd 95, auto, 99k runs great on the road, never a transmission issue at all. As we came to a mild Hill and stopped I decided to put it in the lower gear 2, when I gave it gas it didn't want to move, 1 however was fine. No issues in OD or D. Also, I was not in 4wd at all.
Is this the beginning to a transmission issue? I never notice no power loss or sluggishness when I'm in OD and starting out from a stop as it goes through the gears.
Any ideas?
Thanks

It's because when you shift the transmission into that gear it starts off in second gear.
From a dead stop it's trying to pull a higher gear than first which takes more effort. The reason they allow the transmission to do that is for helping to apply torque to the wheels in a low traction situation. It's akin to the good 'ol days when people were using more manual transmissions than automatic. In mud, snow or ice they would take off in second or higher gear to help reduce wheel spin and get out of those bad situations. I watched my dad get his tractors out of bad situations by doing similar things on the farm. One instance I remember very well was when he was reworking a creek crossing with an old Ford tractor that had a loader on it. The banks were just muddy enough that it didn't want to climb back out and it was too muddy in the bottom to go ahead and cross. I remember him cranking the throttle, putting it into HIGH range and backing it out again. The tractor almost died at the top of the bank barely able to pull itself up the hill power wise but it backed right up it in the higher range like it wasn't hardly muddy at all.

There's nothing wrong with your truck at all, it's just doing what it was supposed to do. However, in the interest of the long lasting life of your transmission I wouldn't do that from a dead stop on a hill anymore unless there was a traction issue. GM also put a switch on the mid/early 90's Grand Prix's to do the exact same thing. Normally in L2 it would shift from first to second and stay in second but when you pressed the switch it would start in second when in L2. The Owner's Manual's explained what I did above, that it was for getting torque to the ground in low traction situations.

I was considering it to be normal, because it was a higher gear, so takes effort to get moving.
I never use the other gears since I got the truck.
So I decided to try them all.
I Know it may have sounded like a dumb question but as far as transmission goes I'm not to knowledgeable as I am with engines. Besides, everything I owned was 5 speed. I just wanted to be sure. Not looking to dump more into it after the fuel pump, spider... Etc.
Thanks
