You pull the lever to 4 high, but the TC lock light wont go off. Sometimes you have to repeat the forward and reverse routine several times. I have seen both H2s and H3s 'pop' into place in about 10 feet after the lights indicating they've been in 4 high. I'm always make sure I hear the clicking sound underneath before I gun it -- because it'll give you a pretty good jolt when it does engage. The noise is stress on the system -- 4high lock isn't made for dry surfaces with plenty of traction. Have you noticed a slight burning smell as well? So, the dealer was right and wrong. Should you need to reverse an H3 to get out of 4high lock? No. Does it help a sticky system sometimes? Yes. Do you get 'stuck' in 4 high lock everytime you use it?

well, i used it in the icestorm in dallas on friday, when i got to work i took it out of 4hi-lock, or so i thought, it stayed in 4hi-lock until i got home. no it didnt smell anything. i noticed it didnt shift out of 4hi-lock immediately leaving work. after i got home, i decided to take it to the dealership because this had never happened before. i backed out of my driveway, then put it in drive and drove off. thats when i noticed it was in regular 4hi. drove to the dealership, and just before i pulled in, i put it in 4hi-lock and then tried to take it out again, just to see if it was still doing it. sure enough, it wouldn't come out of 4hi-lock. i guess im just sort of confused, ive used 4 hi lock before and it had never done this. now it does. i just figured something was wrong because it had never done it before. the manual does say that you may have to back up 25 feet to disengage, i just found it odd that all of a sudden my truck is now requiring it.
