I have the push button auto 4 with 2wd, 4hi, 4lo just looking for something that is either 4wd or 2wd non of this slipping b.s. when I try to use it and a atlas is totally out of the question!

 

np 241 swap, easy, enough said

 

All I said is you will not take a 2500 or 3500 case out and use it on a 4l60. Thats it, MR know it all. U are the one that acts like you know everything and are a complete A$$ Hat. Yes Gm does offer many cases in 1500 and 2500 form, but you cant interchange the 2. Also I never said the 6 bolt pattern would not line up, just that the shafts would not.

I have used an NP241c in my solid axle swap, I know it can be done, and its no big deal. I was saying to go from a 80e to a 1/2 ton case you will need to convert the input on the case to match the output on the 80e, wich I am currently about to start for my swap, cause like already said the 1/2 ton case is more than capable of more power than most people will ever make.

 

Thanks for all the help guys I just got my hands on a 6.0 l?4 so my swap is next then I guess I need to have the transfer looked at cause it only works when it wants to... ANYWHO thanks to everyone for the help and the

 

But their both still half ton cases. yes you could get them in a 3/4 ton but still there a half ton case. and they will not last forever thats why my 241 needs to be gone through agian after one year of use.

 

Yeah I have a 3/4ton with a 241, dont know where the chain or half the case is I guess in the mud somewhere. I rebuilt a 1/2ton case and put my input shaft in for the time being, but prolly gonna build a doubler 203/205 case. 27/32 spline does seem general but some length differences in years and generations.

 

So the 2500hd autotrac is no stronger then the 1500LD autotrac?

 

will a NP243 fit a 99 Silverado 1500 with a NP246? If so what all is required to do the swap?
