    I know nothing about transmissions, but trying to learn. I have a TB 350 in a 75 K5 that needs to be rebuilt. I just ran across a four speed with granny 1st gear out of a 85 K5 that had an electrical fire yesterday. First question- this is a SM465, correct? Second, will this swap be a direct bolt in? Found the how to write up in the technical section so I will be following that closely. Just a little worried about the different tail shafts, and any other issues that might pop up I don't know about. Thanks for the help.

    yes its the sm465/np208. this swap is not a bolt in swap for the older trucks. you will need driveshafts, and redrill the frame for the crossmember. there are a few small things that were changed from year to year, but i have solved them (doing to swap as we speak, almost done also)

    im working on a more complete write up for this swap also, mine is a 700r4-sm465 swap though.

    Spooln- thanks, I downloaded that earlier and have been going over it.

    I will have to find a new crossmember for this, correct?

    you will need a new crossmember because the 85 uses the short adapter.

    Hey, I may take you up on that! If I can get the guy to give me a call back! Swing by a federal reserve on your way up and grab me some money so I can get everything done this summer, OK?:D

    It's not too bad.

    Make sure you get everything. That means pedals, reservoir, master cylinder, hose, slave cylinder, clutch fork, bellhousing, flywheel, clutch, and transmission. It'd also be a benefit to get the crossmember.


    The hose and clutch fork alone are $100 from the dealership. The slave cylinder is like $60 from the auto parts store. The flywheel is $75. A "decent" clutch will cost you $140. Get all the bolts also because flywheel and flex plate bolts are different lengths. You'll need the bolts that go between the trans and bellhousing because they're metric.



    I have $600 into the parts for SM465/NP208 swap and I'm not even done yet. That doesn't include $70 for the clocking ring or the fact that I never opened up the 465 or 208 to see if anything needed maintenance/repair/replacement.

    mine were standard and bellhousing was from an 89 C&C 1 ton.

    i have $290 into everything for my swap (im done BTW), so it does range.

    here is my write up, i even have the measurements for the hydro master cylinder on the firewall.
