So I’ve searched all over and can’t seem to get a straight answer to what I’m experiencing. So I have a Black Bear Tuned 03 GMC Sierra 1500HD with the 4L80E 4 Speed Automatic transmission with the ability to Manually shift 1-2-3. My understanding is that when I Manually shift it down into 1st gear it’s suppose to lock it into 1st gear so it revs up way higher and engine brakes to slow down but does not shift until I manually shift up to 2 or 3 or put it back in Drive. Well when I lock it into 1st gear, the revs are much higher but it still automatically shifts to 2nd gear once I get close to 25-30mph even though I have 1st gear selected. Is Manual shift lock not working for me? Has anyone else experienced this? I just don’t get the point of manual shifting if it’s still gonna shift up automatically anyway Thanks for any input!

I have a 03 Sierra and installed a LED light bar with dedicated harness from the battery to a switch inside the Cab. So my light bar ran perfect and then I started noticing when I turned them off, they would still flicker. So I bought a Load Equalizer and installed that in line close to the light bar and screw it to the frame. I go to turn my lights on and now they flicker while ON but turn off fine. This might be stupid simple but could that mean the Equalizer is bad? My connections are pretty solid.
