Transmission support crossmember for M1009...

[Alexander]

I’m in the midst of putting together a M1009 that I got without an engine, transmission or transfer. I now have the original TH400 and NP208 from another M1009. I also purchased an “organ donor” Blazer that came with a SB 350, 700R4 and NP241. My question is can I use the transmission support cross member from the donor vehicle on the M1009? Is it the same as the original? Also, I remember reading something about the positioning of the spaces for the crossmember. What’s the correct way to install them? Thanks for any help.

PS… If this crossmember won't work, will one from a 88 Suburban with a TH400 and NP208? I have a shot at buying one of those.

I dont think that the crossmember for the 700r4 is the same, but i'm sure that you could make it work. A few of the guys have put 700r4's into there trucks and would be better able to answer your question. The one off of the burban should fit perfectly, since its the same frame for the most part.

I bought the Suburban... now I have to find a way to justify it to my wife, or hide the financial transaction and vehical from her. This might be the last time I post for a while...

Actually both crossmembers are teh same, its the pedastal that they tranny/transfercase attach to, that is different.

Wait a minute. What are you trying to put where?

If you want to put the 350/700r4/241 in the M1009 then yes you can use the crossmember from the Blazer.

If you want to put the 350/400/208 in then you can't use the crossmember from the Blazer.

I'm not sure if the 208 and 241 are a direct swap but I think they are.

If you don't want to use the 350/700r4/241 set-up then why not?

The goal was to put the 350, TH400,NP208 into the M1009. I don't have the original M1009 crossmember... but have the one from the donor Blazer (350, 700R4, NP241 set-up). Unfortunately the 700R4 was traded off in another swap. I suppose I can go to a Chevy dealer and see if their parts books can confirm if the crossmembers were the same, but I thought I'd take the lazy way out and ask the list. There is generally a wealth of knowledge here.

alex, a great place to ask would be on coloradok5.com

just ask if you can use the same xmember when swapping the drivetrain in the truck.

i do know that a 241 will go in place of a 208. if you need anything for you project i took apart 4 cucvs so far.

 

[mangus580]

What blazer had the 241 in it?

Every NP241 i've seen has the front output on the drivers side. They came in 92 and newer blazers/tahoes. And 88 and newer Pu's. You can use any crossmeber from any 73 though 87 pickup. Some have lower steps to change driveshaft angle. But they all use the same 4 bolts to hold them up. The corss member is also slotted on the pass side to take any 203, 205, and 208 adaptor.

Thanks for the input/comments, guys.

I did post the same question in the coloradok5/grarage forum (thanks to cut and paste). I had a far better and seemingly more cerebral response from this group... that should be taken as a complement to you all. I will soon find out if the cross members are the same... sometime within the next two weeks or so, when I try to assemble this jigsaw puzzel.

I did notice that no one had any thoughts on how to hide the suburban purchase from my wife... maybe too tough of a problem even from this group.

84cucv1ton... I need to contact you by email. I might need to buy a crossmember or some other piece.

Thanks, Alex
