Re: Polar Bear Suburban
That is looking great! I can't wait to see the trans swap.
May have already answered this, but are your plans to take it on big expeditions like your truck? If so, we'll definitely expect a lot of pictures ![]() |

Re: Polar Bear Suburban
Larry, it is looking awesome! I like the paint job, and the lift made this truck look sweet. There's only one thing I'd change, just because it drives me nuts.

Re: Polar Bear Suburban
I think that is a Suburban thing.
My 68 has the same look without a shackle flip.

![]() The shackle flip does swing the axle forward a tad where a small .5 to 1” offset zero rate would move it back a where it would be centered. At the moment the rear shaft is almost too short so I wouldn’t want to move the axle back just yet. I’ll wait to see what driveshaft work needs to be done when the NV4500 project gets underway then may add a zero rate to move the axle. I don’t even notice it and even far less noticeable in person. I agree, with vectorit that this might just be a Suburban thing as even the pre-lift pictures look like the axle is forward a tad. Funny though that nobody noticed stuff that really matters like the front axle not having the caster shims installed yet and the front tires layed down like road grader tires when they are turned all the way left or right. Installing caster shims this weekend. ![]()

I'm in. Great build! I'm thinking about moving to Colorado but that yuppie Texas Atv statement has me thinking it could be a little commercial for me.

Re: Polar Bear Suburban
Had the week off for the Christmas Holiday and got the NV4500 swaperoo done! A NV4500 is far from a sports car transmission but compared to the SM465 it certainly is! Plus OVERDRIVE is such a beautiful thing! It is amazing how just a transmission alone can change the personality of a vehicle.
The dirty end of the SM465/NP241 before teardown ![]() At this point, I had some major work ahead of me to rework for floor for the new shifter location, which is 6” further back on the NV4500 ![]() 465 vs. NV4500 comparo. They are right on the money in length. The drive shafts were a direct fit as well as the trans cross member. I was even able to reuse the trans mount. ![]() ![]() New Centerforce clutch installed ![]() AA Bell housing installed ![]() Getting ready to go to town! Aligned the trans jack at 20 degrees to match the angle of the engine for quicker poke'n action ![]() ![]() Reused the original 465 32-spline NP241 transfercase after my buddy and I took it apart too see how things looked in there. ![]() The really nice thing about a 241 tcase is even a little wirey guy and pick them up to stab by hand. Can’t say that for the 205 in the K10 ![]() Then spent half day reworking the trans tunnel. Sorting through these details is where the big time gets burnt up. ![]() Hacked up this trans tunnel to build the new one. Originally I had hoped to just swap on an automatic trans tunnel then cut in a new hole for the NV4500 shifter like I did on the K10. Ah, nope! The floor on ‘85ish and later trucks do not bolt off and they are shaped different than the old removeable tunnels too. ![]() Almost final dealeo ![]() No NV4500 swap is complete until you dump in $72 worth of super juice ![]() Before tear down. SM465 transmission ![]() After with the NV4500! Used the leftover 205 boot and bezel from the K10 when it got a NV4500 and twin stick 205. ![]() ![]() It took all day yesterday to install the ACC carpet. Damn Burbs have a 1000 holes to cut through the carpet and jute. What a pita! Replaced the carpet from barn doors to firewall. I bet I went through 20 razer blades trimming this dang carpet! That jute is dense! ![]() ![]() Same knob I used on the K10 a few years ago when it got a NV4500. For some reason, I knew it was a good idea to buy two knobs at that time! ![]() I put about 30 miles on it tonight and have to run some errands in Canon City tomorrow so that should be a good shake down run for it. So far so good….no leaks, vibrations, rattles, etc. I'll say this, a NV4500 swap in a '85 or later square is one heck of a lot easier and cheaper than doing one in a 70's truck! Now, it just needs more power! Might have to get busy and do something about that ![]()

Re: Polar Bear Suburban
Great Job! My buddy just got a 2wd 4500 for his 88 crew and is setting to do the swap. I will link him this thread. Any tips are appreciated as we will probably start within the week. I just did a th400/np203 to 4l80e/np205 swap. But this manual stuff will be a fresh area for me.

Re: Polar Bear Suburban
Looks great Larry, but there is a little bit of misinformation here:
How is this the dirty end! Well, maybe compared to the "after" scrubbed and buffed transfer case it was. All kidding aside, I'm digging how the shifters look stock and awesome at the same time.

Re: Polar Bear Suburban
Larry, could you have moved the NP241 Tcase shifter to the rear enough to reuse the original plastic housing and boot?
I'm considering the same swap for my '85 with 465/208 and want to retain the original Tcase shifter boot. I was hoping to move the Tcase shifter to the rear since it has a one rod linkage and would be easy to shorten. BTW, Great write up! Thanks, Keith

Re: Polar Bear Suburban
Seems like GM trucks' tranny any t-case shift boots always got the ugly stick treatment. They still look better than some for sure. I never could find a boot that looked perfect in a square body. I think the one you used is the best GM has done. Too bad S-10's didn't use a mini version!

Re: Polar Bear Suburban
I plan on dropping an NV4500 into an 83 6.2 diesel 700r4 suburban.
Does that AA bellhousing accept a factory GM slave cylinder? If so what slave did you buy? thanks
