So, what would this take? When I look I see transmissions with and without integral bellhousing... what do I need? And really, exactly what will I need to do the conversion? Will I be able to use the transfer case, or do...

in my opinion there is no reason to go through all the head ache of finding a swapping all the parts to go manual. to do a good clean swap you will need:

 

brake and clutch pedals and brackets

clutch master and slave cylinder

transmission, bell housing, clutch, flywheel.

clutch lines

steering column and instrument panel from a manual truck,

transfer case may interchange but will need drive lines.

Computer will need changed.

cross member usually needs changed

 

I think its only reasonable to swap if:

A: you have a parts truck that will have everything you need

B: its a offroad toy or beater and you dont care about the little things.

 

The trans you would be swaping in is a nv3500. Its a okay transmission but not really that tough. It was used in s10, jeep, and light duty full size. It you wanted something tougher you better option would be a nv4500 (its a 5 speed but first gear is granny low, so its good for off roading but really only has 4 usable gears) these came in the 3/4 and 1 tons. another option would be a borg warner t5. They are tough and common to find, how ever I dont know if they were available in 4wd vehicles, so you may have to make a adapter for the tcase.

 

The gm automatics are all quite strong and if you do break one replacements are cheap. Through a shift kit in it and a extra transcooler and you probably wont ever need another one. If you really feel that you need something stronger I would recommend upgrading to a 4l80e auto, they will be easier to find all the needed parts to swap and will be less work.

Unless your truck is something really special, another and probably the best option if you insist you need a manual trans is selling your truck and buying another.

 

The manuals aren't real common but if you save a little money and can be without a truck for a week or two you can probably sells your truck and find a 5spd truck. maybe upgrade to a 2500 or one in better condition.

You will also need to make sure there is a place in the end of the crankshaft for a piolt bushing.

I put a 5.3 LS in my 1992 but it had a 383 stroker before that. Upgrading to a 6.0 LS in the spring.

I want to manual swap a 95 or 96? Think it's a 96 GMC Silverado 1500 with a fully bored out 383 stroker. I was talking to my mechanic friends and everyone said the nv4500 (would be my go to) is more of a diesel tranny meant for lower torque, and it would not be the best idea?! Any input??? Thanks!!! - Stephen

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
