I will be in for one as long as this actually happens. Another NJ owner will be needing one before I do, so I will sell them mine so they can start their build, as long as I can get a replacement here.

Lets go people, only need to sell 2 more!

Re: Mark Williams 32 Spline input shaft group purchase Try # 2

My truck has been sitting in storage for years, with an LS1 next to it. I recently decided that I am going to make a go at it this winter since my roommate is finally getting his RX-7 out of the garage. I know, Syclones, RX-7's, we are gluttons for punishment. Anyway, it took me quite a bit of searching to find this thread and it appears the parts market has changes significantly in the last 4 years since I did any research. So you guys need to sell two more of these? What else am I going to need to mate up the trans and transfer case? Just the mounting plate and cross member that RPM sells? Sorry if these questions have been asked repeatedly but I've been digging through old threads all day and have seen a lot of different info. I'd hate to spend this kind of money without knowing exactly what else I need to make this happen.

Thanks guys!

yes, you basically need the adaptor to mount the trans to the transfercase, there have been great parts developed for that as well (see this thread), or you can use the one RPM sells, either way it will get the job done, then a trans crossmember or some people have modified / welded up their own.

Re: Mark Williams 32 Spline input shaft group purchase Try # 2

So just since I like to double and triple check everything, and also because I'm rather caffeine deficient today, I want to clarify what I've looked into just now. I keep seeing your posts so I'm assuming you know your shit.

I'm gonna start from the begging. The 700r4 is not the best trans for our trucks and making power. The 4l80e is much better, but does not mate with the 4472 t-case because the tail housing bolt pattern is different and the input/output shafts are different. So we came up with a new 32 spline input shaft for the t-case and an adapter plate to mount up the trans tail housing with. Due to the addition of the adapter plate, the input shaft needed to be longer than stock. Since then we now have these billet tail housings that eliminate the stock tail housing + adapter. However, since all those longer than stock input shafts are on the market, the billet tail housing was made at the same overall length of the stock housing + adapter plate in an effort to not obsolete the 32 spline t-case input shafts. There is currently no 4l80e stock length tail housing designed to bolt to the 4472 t-case while using a stock length 32 spline input shaft. And that's because as I mentioned earlier, we already have the lengthened shafts that were designed to be used with the adapter.

Is that what has happened over the last few years?

I've also seen a few people question if the setup would work with so and so's input shaft, with the general consensus being yes. Are all the 4l80e - 4472 input shafts pretty much the same in regards to their overall dimensions?

Edit: My truck has been on the far back burner for many many years. I pop into the community every now and then to see whats new and there is always something different. So I get an idea in my head about how I'm going to do this, but then a year or so later there's a better way to do it. Unfortunately this leads to confusion on my end as I'm never 100% focused on it. It looks like I'm actually going to dig into the truck in a few weeks so I just want to have everything in order. Thanks for you help and patience!

I've been in the SyTy game for 14 years, but I will never claim I am an expert. There is always someone who knows more, goes faster, and so on. I will do my best to clarify everything.

The 700R4 is a decent trans, but when coupled with AWD, it is the weakest link in the drivetrain. The first 4L80E installs used the plate style adapter and a resplined 4L80E output shaft (reduced from the larger 32 spine to a smaller 27 spline to work with the stock transfercase)

Eventually, JSM stepped up and designed a 32 spline input shaft for the transfercase so the use of the weak, resplined transmission output shaft was eliminated.

Following that was the billet transfercase adapter which eliminated the quirky and difficult to use plate design adapter.

I do recall reading about different output shaft lengths and designs, but I believe the OE 4x4 output shaft is what everyone uses.

I've also seen a few people question if the setup would work with so and so's input shaft, with the general consensus being yes. Are all the 4l80e - 4472 input shafts pretty much the same in regards to their overall dimensions?

talking in terms of mating up the trans and transfercase, this T-case input shaft is of exact dimension of the OE piece it replaces, so there should be zero issues with it. According to posts on the forum, either adapter will work as well, but the billet one is clearly a better design, easier to install, fewer spots for leaks to occur, etc.

I hear you, my original Ty hasnt been on the road in 8 years, Ive just been collecting parts for it and working on other ones in the meantime.

The only thing I failed to mention before is that you will also need different driveshafts due to the 4L80E's added length. I believe its about 3" difference, so you will need a shorter rear driveshaft and a longer front propshaft.

As far as running the trans, there are many different options for that, stand alone trans controllers, using a GM TCM, or going with a stand alone engine setup that will also control the transmission.

Thanks for clearing that up!

Ive got a complete pull from a 2002 trans am with a wiring harness and computer, so I'll figure something out with that. My roommate is fairly good at wiring, I'm more of a fabrication guy. Now I just need to swap the 4l60e on the back of that motor with a 4wd 4l80e. Anyone wanna trade? :D


Count me in for one btw.
