97 tahoe 5 speed swap

[87carl]

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 cylinder first. Cutting the floor for the shifter and 4wd shifter will be easy the spots for them are already stamped into the floor. Doing 5spd swaps on early 90s chevys alot of the threads I have read said that they had to weld the upper bracket for the clutch pedal in place because it wasn't there. (were the bolt that's hidden under wiring harness that I keep fight with is) but I am about 80% sure I see it up in there on the Tahoe still gotta move stuff like the wiring harness to get a good look of that.

All I would need is the dash it's self. Don't need any of the other stuff. If it is something that you would be interested in sell would you mind sending some pics? I might be able to fix the broken defrost vents if there not too bad and there are no other cracks running through the dash. My email is rodneypowell01 (at) yahoo.com. also it might be easier if you remove your dash too to get to some of the harder to reach areas and if you have to weld anything would definitely be better too.

I am not sure of how you would ship a dash without it getting broken? Do you know? I can get Pics of the z71s dash tomorrow

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 safety switch on the left side of the Trans just above the shift linkage. From what I am reading I need the purple and yellow wires from it to connect to the nv3500s neutral safety switch. Hopefully I just pulled the linkage slightly out of park when changing steering columns and that's why it won't crank now I will climb under it and make sure it's fully in Park tomorrow if it still won't crank I will connect the purple and yellow wires I just mentioned to bypass neutral safety switch and see if it will crank over. If it still won't start I will have to keep searching. Hopefully purple and yellow are the rite colors.

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

http://www.fullsizechevy.com/forum/...torations/410690-88gmctrucks-nv4500-swap.html

Anyone know of any other good 5spd conversion threads most I find googling are people asking will it work not much detail on doing it

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

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.

One other thing i want to fix on this truck is that if you leave it off for more than an hour she won't start unless you prime it by cycling the fuel pump 3 or 4 times then she fires rite up what can cause that?

That is the wiring printout for the 4l60e range selector / neutral safety switchs 7 wire connector. There's also a 4 wire connector but none of those wires are needed. For a 5 speed conversion we need pins C E F and G on the seven wire connector. Pins G and E are for the neutral safety switch or clutch pedal start switch you can either can connect wire to them and run it into the cab and connect it to the clutch pedal switch or pull them back out of the loom then thru the firewall and connect to clutch pedal switch. Pins C and F are the reverse switch wires the reverse switch is on the left side of the nv3500 mines wires are the same colors green and pink cut the wires off the 4l60e range selector plug and connect them to the nv3500 reverse switch plug. That's what of the wiring i have figured out so far. Still got to figure out if the wires on the transfer case are the same or if different. On the transfer case is the vss sensor for the speedometer and a 4wd indicator sensor that tells the front diff to engage and turns on the 4wd indicator lights in the cab telling you its in 4wd. I am hoping the plugs will be the same between transfer cases but if not i will post what i have to do to get them hooked up.
