I am gathering parts now to put a 700r4 in my 90 Silverado. It currently has the NV3500. I know I know, why would anyone swap manual to auto. I hate towing with a manual and I hate backing a trailer up with a manual even more. Since 90% of my truck driving is towing, I'm switching. So, don't waste your time asking why or trying to talk me into sticking manual. :P
Ok, hopefully someone knows stuff about both trannys. Length? Is there any chance they are both the same length in 2wd form? Along the same lines, I have the 700r4 that has more splines(dont remember the number, 30 maybe), I can't imagine the NV3500 also has 30 splines, could it? I'm really hoping I can reuse my driveshaft. I don't mind changing the yoke to make it work. I'm just too cheap to buy another shaft.
I'm trying to stay away from changing the column. Anyone ever seen a truck with a floor shifter? I happen to already have a big ass hole in the floor of my truck, might as well put a shifter thought it.
I'm expecting to modify the tranny x-member. I figure I'll buy a mount for my truck with 700r4, then make it work with the original x-member. I own fab tools. Any other thoughts, concerns, suggestions? I'm by no means afraid of the swap, but not being too familiar with it, I figure I'll do what I can to gain info.

90's chev trucks are a dime a dozen, why waste your time, sell that one and buy an auto one.
-
i really like this one. body is straight, frame isnt bent between the cab and bed like 90% of them around here, i already put a crate 350 with 4 bolt mains in it.

Early 90s Chevy trucks in nice shape are rare, and command a little bit of money around here.

this one is super clean other than needing paint. no rust at all, one or 2 very minor dents.

Does anything rust in Florida?

Back to your questions, 700r4 is 30 3/4" bellhousing to tailshaft, so I'm sure you can roll under your truck and figure out how long your nv3500 is and compare. It is much better for you if the 700r4 is longer especially if you need the yolk changed as you likely will. It is typically very minimal cost to have a shaft shorted when the yolk is being changed at the same time.

Being somewhat of a noob to rwd, can driveshaft places modify aluminum as easy as steel? My current shaft is aluminum. It's huge so I imagine handling the torque isn't an issue.
-
yes they can mod it. But I believe it cost more.

Yes they can, as was mentioned it does cost more, get a couple quotes if it is going to be a lot, I would go find a drive shaft from a 700r4 vehicle in the JY.
