    My friend needs help with a project he's working on. He's wanting to swap a NP241 into it to get the lower low rante. It currently has a NP205. It has a TH350 out of a 76 K20 in it. Will this bolt in directly if we find a GM case? If not, what do we need??? Thanks all for your help /forums/images/graemlins/truck.gif /forums/images/graemlins/usaflag.gif

    Why on earth would you swap out a 205 for a 241?!?! /forums/images/graemlins/eek.gif Keep the 205, and get either a Doubler or a Klune-V. The lower range isn't worth the strength you lose. But, if you're really hell-bent on putting a 241 in it, you will have to do either buy a custom adaptor, or wait until one of these other boys chimes in with a response. The 241 was never offered with a TH350, only TH700's and 465's. I think that a 208 adaptor will work though, not too sure. The tailshaft might be too short.

    If I remember correctly, the 241 is a direct replacement for the 208. Therefore, the TH350/208 adapter should work.

    You just need to find a 241C from an 89-91 Blazer/Jimmy/Burb with a TH700.

    Look for one from an 89. It will have the mechanical speedometer on it. After that, they went to electronic B.S.
