Twin Stick Transfer Case in a 1/2 ton?

I guy that works for my father was asking around weither anyone knows anything about a twin stick transfer case in a 78' chevy 1/2ton 6' bed. He remembers it being able to convet to front wheel drive in 2wd HI.

Any one know anything about this. It was bought new from the factory in '78, nothing aftermarket. As he remebers it there was not a PTO on it, but he was younger when he saw it so thtat he might have over looked.

<font color=green>I know of no factory twin stick cases in any Chevy, that seems to be what you're asking. There are ways to covert the 205 to a twin stick, but it's kind of a home-brew deal, they never came like that from the factory.

Was it twin stick or a PTO shifter? If it had a pto it would have a shifter for 4wd and a shifter for the PTO.

Re: Twin Stick Transfer Case in a 1/2 ton?

speaking of twin stick for a 205, is there an afterm market kit for it, or does it have to be made from scratch?

You can by the handles, but the mod. of the t-case you have to do, unless you pay a shop like ord or something to do it for you. But, it's not that hard. You just pull the springs and detent balls out, slide the shifter rails out, grind a groove in one, then slide them back in and put the springs and detents back in and your done. Peterson's mag had an article on it a while ago. I'll see if I can dig it up.

Re: Twin Stick Transfer Case in a 1/2 ton?

Yeah it is actually quite easy to do once you know how the 205 works. I have heard that you don't even have to take it right apart to make it work or do grinding like Jason said. If you want to see something more complicated try taking a SM456 and making 3 individual shift levers. One for Low and 1st gear. The second for 2nd and 3rd gear and the 3rd lever for reverse. It actually sounds hard to do but it is actually very very simple to do. Eventually I will post some pics on how and why I did that mod to my pull truck!!!!!

Re: Twin Stick Transfer Case in a 1/2 ton?

On a SM465?? I can understand how to do it on the "car" tranny's because the shift linkages are on the outside, but would be pretty complicated in the 465 wouldn't it??

I recently went through the shift rail twin stick mod on my 205. It is really easy, but I had mine on the bench, and glad I did. I went through some of the berrings, gaskets and seals while I was there. Had a lot of trouble getting that damn pin out that holds the rail to the fork inside. It's a neat mod, but I'm not sure if I'd do it again. I havn't made the shifters yet. Still crawling under the truck to shift with a screwdriver!!

Re: Twin Stick Transfer Case in a 1/2 ton?

Actually its really really simple if you think about it. Im not sure if you know exactly what the SM456 looks like but up on top (the shift lever housing) on the transfer case side on the back there are 3 round circles indented into the housing. Those are plugs so you can take the actual shift forks out when rebuilding it. Anyway, all you do is pop out those plugs and tap the 3/4" round rods at the end and then get bolts(I am using threaded rod with a hiem joint on the end). Then on the heim joint and I am making the linkage for the new individual shift leavers. I also forgot to mention that I removed the stock lever and machined the housing down so it was totally flat and then welded a piece of 1/4" flat stock to it so that it sealed the case.

It was really simple and the reason I did this was so I could put my center counsol (the truck is a center seat) right over the trany and there would be no way to make the shift leaver work.
