My 4l60e is starting to show its age a bit. Not ready to condemn it yet but it occurred to me that it would not be too difficult (on the scale of trans swaps) to put a NV4500 from a GMT-800 HD truck in place of my 4l60e. I've done a bunch of research on which part numbers I would need and it seems mostly manageable but I have run across something I can't find the answer to online. My NP246 transfer case has the 27 spline input shaft because it's currently hooked up to a 4l60e. The NV4500 has a 32 spline output and was never (as far as I can tell) offered with a NP246, just the NP261 it seems like. However there's a part number for a 32 spline input shaft for a NP246. If I install that input shaft, will I be able to put my NP246 behind a NV4500?
MY OWN TRUCK is a 1999 Silverado Z71 LS 5.3l 4L60E with 195,000 miles, and it always starts, always runs, gets me down the road, and the job done, without fail. Paid $1800 two years ago, with a bad rear end. Installed new water pump, starter, alternator, new brakes all around, and rebuilt the rear-end myself. Wasn't at all easy, or cheap, but it was worth it. Now, my transmission needs to be either rebuilt, repaired, or replaced; neither of which will be at all cheap, or easy for me I know, but I have somehow managed to have a potential swap fall in my lap, and it was free. The replacement tranny is a 4L60E out of a 1999 Escalade 5.7l AWD, that's only got 90,000 miles on it. Things been sitting for about a year, is complete, and has (had) no known issues. Lacking the means, knowledge, and/or financial resources to make repairs (Sun Shell thing broke) or to pay someone else to fix it, or rebuild it, or the time to wait until a busy shop can get to it, I'm preparing to make the swap myself, but with the assistance of a few buddies, some of their tools, and hopefully a collective of experience and knowledge to do the job properly. What I'm asking for here is a little help with the particulars, and I could definitely use any and all the help I could get in the way of advice, direction, caution, tips, pointers, hints, do's and don'ts, and a few nuggets of wisdom. Steps, or some order of operation, would be nice, but first I was hoping for a confirmation on interchange fitment, relative suitability, difficulty in completing the swap, should the swap be less than a good fit, but perhaps still do-able. So.. First, is my OKXD swap compatible? I've done quite a bit of research, but still haven't got a simple, definitive "Yes" what I was hoping for. Is it even possible to keep my PCM with a tranny from a 5.7? The Bell Housing has a bolt hole top-center (I was told that was for diesel motor engine application) and the Torque Converter TMBX 242-4393 has three holes for bolting up to my Drive Plate. Both are two-piece (Bell Housing to Gear Box), and both include 4WD/AWD coupler 15724744-YDC-5 to Transfer Case (Transfer Cases are the same? My truck came equipped with Automatic 4WD) so are there any issues with this swap? Second, if compatible/interchangeable, what should I do first, besides drop the driveshafts, transfer case, crossmember, and pull plug-in connector, linkage, etc? Is there any prep I need to do to ready the replacement unit? It has been sitting somewhere in a guy's garage, gathering dust, dirty, a little crusty, does it need to be flushed, primed? Should it be checked to make sure the electronics are not friend, switches operable? Third and last, what are my odds to complete this swap, by myself, the first time, and still be able to drive my truck another 100,000 miles? Any input, comment, criticism would be much appreciated, thanks!
