Fixed Yoke 208 Questions?

Discussion in '1973-1991 K5 Blazer | Truck | Suburban' started by **DONOTDELETE**, Jul 24, 2000.

    What year trucks did this transfer case come in?
    Mine is a 82 K5 and it has the slip yoke,would it be worth the trouble of converting to the fixed yoke?I like the low gear in the 208.
    Also i have a 78 K5 with a 350e/350t combo.My 82 has a 700r4 will the turbo 350 bolt up to the 208 transfer case,I know that the tail housings are the same but what abou the shafts?

    I don't believe any GM trucks used fixed yokes on their 208s or 241s. Dodge used fixed yokes on 241s (and maybe 208s)...might be worth looking into for your 208.

  2. I've read somewhere that they used both the fixed and the slip on gm's in the early 80's,just never seen one though.
    I have a fixed 203 but dont want to give up the low gearing of the 208 for a 203.
    I would like to do the doubler thing but dont have a 205 or the cash right now!LOL.

    The answer to your question is NO!!! The 208 case will not bolt to a th350 tranny without serious mods. You have to replace the shafts in the th350 tranny with the ones from the 700r4 and then I think you still have to get a spacer plate although i"m not possitive. Mates- th350+205,700r4+208, 4-speed+203. Like I said you can change these around but they are all internal tranny mods. so save up your spare change.

    I am not familiar with a fixed yoke 208 being offered from the factory on GM trucks. The 203 and most 205's were fixed yokes. Several companies offer fixed yoke conversion kits for the 231 and 241 cases, but I do not believe they are available for the 208.

    Hey k5king, TH350 and 208s were the only auto combo you could get in 1/2 tons and k5s in 1981, so adapting a th350 to a 208 is easy...just find an '81 350/208 combo!!

    A 350 will fit onto a 208, you need to find the correct adapter, try advance adapters and expect to pay some cash. A friend paid 500 for to hook a 400 up to a 205. The main mod is cutting a little bit off the tranny main shaft with a hack saw to fit into the 208.

  7. Well i talked to advanced adapters,they said that the factory adapters are the same.
    The only differance is the tail shaft,you have to cut yours or by theirs.
    You could also goto a tranie shop and get a tail shaft for a 81 4X4.
    Thanks for all the help,and reply's.
