First time Jeep owner, took this new to me 2013 Wrangler 2 door up to the snow. All stock except wheels and tires, 33” Nitto Ridge Grapplers. Started up a small incline in about 12” snow. And the traction control started and I felt like it was slowing me down, I gassed it to try and continue up the road. It made it worse. I floored it and my RPM’s would really go up and barely spinning tires. Couldn’t make the hill in 4HI. Backed down and got more run at it. Made almost all way up and same thing. 3rd try I turned off TC and was great, had good RPM and wheel spin for a little while but the a light came on, Jeep with squiggly lines behind it. I assume traction light. Really bogged me down, made it but didn’t go up nearly as good as my sons 2001 GMC 1500. Is this normal, or am I doing something wrong? Thanks for your help!
