My 700r4 just blew and am thinking about a manual swap since i was about to swap a vortec 350 in anyway.

What would i need for the manual swap? I need overdrive so i guess a nv3500 or 4500 would be the best option? I dont tow or anything so the OD and "honda" shifting sound awesome.

That depends on a few things. 2WD or 4X4?

I assume 2 wheel of he needs overdrive

Most four wheel trucks have oversize tires that create their own overdrive effect

Well, my opinion the best street driving transmissions would be the NV4500 which would require some work for sure. The NP 833 is nearly a drop in for most cases, if you can find one. There’s two variations, 2WD and 4X4.
The NP 833 is pretty much the same final ratio of the 700r4 if I recall.

Hot Rod PC did a nice write up on the NP A833.
I found one last week in a local junk yard in a 4x4 but I'll have to read his posts again to figure out what more I'll need and determine if I can do it.

For sure, that's a good read. I think your biggest obstacle would be getting the transfer case input switched out to the right one. Which is not bad.

Can you tell me what that entails? This will be a first for me. Thanks!

So all you'd need to do is have a 32 spline NP208 or NP241C and bolt it to that tailhousing adapter and you're good to go. Those came on pretty much every other trans option. So you can either just get the input shaft and install it in your's or get a whole unit thats correct. Either way should be doable.

The first thing I did to my '84 C10 was to remove the leaking TH350 and replace with a Muncie M20.
I am not concerned about doing truck things with this C10; only having fun.
The pedal box was a bit of a pain.
I found mine on the fabled online auction site and cost me $225.00 (my offer; listing price was $275.00)
You will need to pay attention to your braking system as apparently parts roe hydra boost differ from those with vacuum assist.
Installation was quite involved as well. Steering column needed to be removed and some bolts on the firewall were a real challenge.
It had been cleaned and painted and came with an almost complete manual linkage setup.
Only part missing, and a real pain to find was the frame mounted bracket for the bell cranl.
Go hydraulic to avoid this problem as well as header fitment.
All parts except the driveshaft bolted right in. the DS had to be shortened 3" and the speedo cable needed the stock 20" extension.
I also had to change the way too high 2.73 for a 3.73 posi.
Anyway, if you choose to move in that direction, good luck.
