Made some progress today. We got the nv3500 out of the z71 and cut the z71's floor out to use as a template so i know exactly were to cut the Tahoe floor.
Despite being 2 am curiosity got the best of me so I went out to check. Turns out the shifter on the 4l60e won't lock into Park without the cable being connected to the column so I pulled it into neutral and the Tahoe started rite up perfectly. So that's awesome :)
Just found a thread from 2012 about a guy doing a 5spd swap with nv4500 in a 99 tahoe.
http://www.tahoeyukonforum.com/threads/nv4500-going-into-99-2-door-tahoe.37537/
Another 5spd conversion thread is 88gmctrucks thread on fullsize not a tahoe but still lots of good info...
I have been searching online the thing on the right side of the automatic steering column that connects to shifter and has 2 wires going into main connector is actually the shift interlock that makes it so you can't shift out of park without pressing the brake pedal. The 4l60e has a neutral...
Another kinda hard part will be drilling the hole for the clutch master cylinder the spot for it is stamped in the Tahoe firewall but there is no way to get a drill and hole saw straight on it without removing a bunch of other stuff like the fuse box computer/abs bracket and possibly master...
From what I read online You could special order the nv4500 in a half ton but not many got it. So I figured this was probably the nv3500. Couple days ago I looked under a friend's Truck I know has a nv3500 and it look identical to mine verifying mine is the nv3500. And ya they are plenty strong...
Oh and most of the cut wires on the dash were either on the steering column or were on a trailer brake controller that's being removed this tahoe will never need to pull a trailer that's what my truck is for. The rest are splices tied on the main start wires looks like some previous owner put a...
Can't wait till warm weather so I can get more done on this project. Hopefully the weather idiots are right and next week will be in the 60s. Till then I keep doing little things on it. Changed the computer to the z71s computer changed the gauge cluster so it no longer says prnd321. And changed...
Weather has been shitty snowy windy and freezing so haven't been able to do much but I started pulling small parts off the inside of the z71 today. In hooked the shifter almost got the 4wd shifter out but the bottom bolt is being stubborn turns easy most of the way but locks up tight when it's...
They want 600 firm for the 80s truck forgot to ask what year. It's got a running 350 engine no transmission no fenders doors bed or hood but I won't need any of that I just need the frame axles suspension and drive shafts transfer case and probably steering box could probably get 300 back...
If everything goes according to plan I will pull the axle bumper and tail lights off the z71 and cut the drivers side of its frame the rest of the way we're it's cracked and remove the entire back half off that truck tomorrow.
Has anyone ever seen anything about someone shoving an 80s...
I got the z71 home today :) Can anyone tell from these pictures if it is a nv4500 or nv3500?
Also how do I identify which rear axle is in the z71 forgot to take pictures of the axle I plan to use its axles because the rear axle has posi and I want to keep the gearing and everything same as...
Found it it's hydraulic clutch line disconnect tool otc 7910 amazon had it with free two day shipping for 15 bucks so it will be here Monday. The new clutch kit I ordered will be here Monday also.
I picked up a Haynes manual today figured it will help a lot with this swap. I have worked with 70s and 80s vehicles alot but not much with 90s vehicles so all electronics and the hydraulic clutch are new to me. While reading the Haynes manuals sections on removing the standard tranny and the...
Frame on the Tahoe was worse than I originally thought :(
So I cut the whole bottom section off.
I will rebuild the part I cut off with 3 /16th plate probably Thursday. Tomorrow I got to replace the coils plugs and intake on my dodge and do to scheduling issues won't be able to trailer...
So by using everything from the z71 the parameters should be met in the z71s computer so check engine light shouldn't be on? And if I get both bins on the registration the vin in the computer will match one on the registration and vin on body will be other one on registration so I shouldn't have...
I am not just going to swap trannys I am swapping everything from the z71 to the Tahoe except engine but tahoe has same size vortec 350 engine. And I live in new York so as long as check engine light is off I can get it to pass inspection emissions are not checked in new York. All the parameters...
I ain't as familiar with newer vehicles electronics what do you mean about driving parameters? I plan to use the axles from the z71 and stock size tires so gearing will be accurate motors are the same size in both vehicles. Again i ain't very familiar with computers and all that but i figured...
I got to go threw and trace all the cut and unhooked wires go still i don't know were half of them go yet. Do to the broken frame i couldn't squeeze under the z71 to see which tranny it is probably just a nv3500 i will pick the truck up with tractor when i get it here Thursday. Would prefer a...
Does anybody know were to download wiring diagrams for free? I was jus looking under the tahoes dash and there's a at least 15 or 20 wires i have found that are cut and just dangling. So gotta go thru find and fix all of them and will also need wiring diagrams when i wire up the clutch switch...
also with the parts truck being a z71 is there anything else I should swap off it? I plan to use its posi rear axle and front axle so I know gear ratio is right. And it's skid plates. Does anyone know if z71s really had stronger Springs and torsion bars? I know the z71 has a larger air cleaner...
