    T-case shifting Technique What\'s your method?

    For those with automatics and a 203 or 205 t-case, What have you found is the best way to shift the t-case from 2 hi into other gears? I am trying to get some good ideas to keep the grinding down to a minimum. I thought I might tap the experience of an awsome group of K5 owners[​IMG]. Did a search going back a year, and found really good info, but nothing as to the best "procedure". BTW, my particular setup is a 75 K5, TH350, 203 converted part time, and manual hubs. Thanks in advance[​IMG].

    2HI to 4HI - keep rolling and yank the lever.
    4HI to 2HI - keep rolling and push the lever.
    2HI or 4HI to 4LO - while just barely rolling, transmission in neutral, shove the lever, being sure NOT to stop at Neutral in the transfer case.
    N to any other gear. Turn off engine, shift transfer case, restart engine. [​IMG]

    For me, this is what works best (TH350-205):2HI-4HI & 4HI-2HI- trans N, eng at idle & slow roll; in or out of 4LO-trans N, eng at idle or off & stopped. Just pull quick and don't stop in x-fer case N or you probably will have to turn it off to get it back in gear.

    That's good- rolling. Thanks guys. Are you locking the hubs first, or after, or does it matter?

    First I get my wife good a liqured up. Then get her to put on her thong bikini. Then while driving about 60mph I dare her to crawl out on the hood and lock the hubs and crawl back. This gives me woo....ohhh never mind just one of them booze induced fantasy's
    on my 203 equipped trucks (75 & 79) always rolling. If going for low put the tranny in N and shift till harts content. Just never dilly dally in neutral on the case. My 75 is still full time the wifes 79 is part time. I found locking the hubs then rolling is best to do on the converted truck.
