GM manual trans specs - 4spd 5spd 6spd 2wd 4wd - LS SBC BBC

Here's a bunch of info and dimensions about GM/Chevy manual transmissions.
T5 vs T56 vs NV3500 2wd
SM465 vs NV4500 vs ZF6 4wd
Update: shifter position matches on all my full-size truck transmissions. However, most SM465s had the shifter a couple inches further forward. Mine is the GMT400 style 88-91 with the aluminum top plate.

Very very good video..and very helpful for me..made me realize how many different ones there are to choose from.. I've been using the nv3500 behide 350's in 40 & 50's rat rod cars and everything has been super easy to make it work perfectly.. the shifter location lands in a good spot..and I use S10/Silverado fluid reservoirs ..and truck pilot bearing

[@GEARHEADdezign]

Yeah the nv3500s get a bad rap, but they work pretty good really. I have two in my Blazers and have no complaints

[@grantlloyd23]

Hey GH Dezign, This is really great info! Thank you for going to the effort and sharing your knowledge here. Just a couple of things; There is no way the SM465 (CH-465) has the same shifter to bell-housing (face / back of engine) measurement as a NV4500 or ZF6 S6-650. I have a ZF6 S6-650 sitting in my garage waiting to go into my 89 1ton square-body dually. It is 15.75” as you say. I do not have a SM465 here to measure up; it must be a lot less through looking at the factory cutout impression in the truck’s transmission tunnel. I don’t have a NV4500 here either. If it is the same measurement as the ZF6 S6-650, that’s good to know and a help for this swap. 2nd thing and you may be just the man to ask this. I am mounting the ZF6 S6-650 to the original TBI 454 L19 (IV Mark 4, 2 PC seal). What flywheel pilot gearing and clutch Assy do I need? What I do know; the trans input shaft is 10 spline Ø1.375”and I will have to use a concentric slave cylinder. That’s about it. Thanks for your help! Cheers, Grant.

[@GEARHEADdezign]

I finally had a chance to measure my sm465, and we're both right actually. Good catch! Mine is 15.75, but it's different than most of the ones I see online. Mine came from an early GMT400, and the shifter tower is offset to the rear. Photos I see online (presumably from square body trucks) the shift tower looks basically centered. So I'll put a note in the description specifying this.

[@danieldouglas8034]

[@deereboy7483]

Gearhead Design I have a 2004 4.8 4wd silverado with the nv3500. my goal is to build something of a sport truck. My main issue is the NV3500 just feels choppy. I'm not sure if maybe the shift tower is bad or what but it has little play in the shifter and the truck only has 62,000 on it. really I'm just looking for a smooth shifting manual 4x4 so if you think a nv3500 is a smooth transmission I will look more into the issues unless you suggest something else. I've also heard the t56 can be adapted to be 4x4 but it was stated it doesn't hold up well with the weight of the truck. Any advice is appreciated and awesome video!

[@jwold11]

The k1500 4x4 trucks had nv3500's in them with an external slave. Some call them a getrag, but in all truth and actuality, they're still a nv3500. 99 and 2000 1st gen nbs trucks used an nv3500 with the 4.8-5.3 trucks as well. Very rare to find though.

[@GEARHEADdezign]

Yeah they were 5LM60 getrags. They just got a name change when NV popped up. The old getrag 282 fwd 5spds got called NVs later in life

[@TonyElTigre-kq4ri]

Thanks for the info I have a c20 with a 4 speed and I want a 5 speed in there and this helps out a lot !! I’m assuming I have an sm465 but I’ll have to double check. Been doing my research and this helps a lot.

I did find out the earlier 4spds have the shifter a couple inches further forward than my measurements. My sm465 is from a gmt400 and the squares were different

I have an 02 3/4 ton truck with the floor shift tcase and the 4l80e. The 4l80e is great but my first truck was a manual with the sm420 which I eventually swapped to a world class t5. I miss a stick shift but the one really good option seems to be the zf6 and they're damn near impossible to find

[@GEARHEADdezign]

ZF won't fit your tcase, but the nv4500 will bolt right in. That's the route I'd go in your shoes, and that's what the factory 6.0 manuals were.

I haven't looked into that. But I do know that the tail shafts are prone to breaking, so just a 4wd tail shaft will be close to the price of a whole 4wd trans...

A lot of great info here, thanks! I am about to swap an LS style T-56 behind a one piece RMS Chevy 350 and have heard mixed reviews on what pilot bushing to use. I purchased spacers that go between the bell housing and front plate of the transmission to fix the long input stick out, just wondering if you have any experience with this. Also, do you know for sure if an LS T-56 clutch will bolt to the old school SBC flywheel? Thanks!

[@GEARHEADdezign]

A friend of mine has done that exact swap, you use the SBC pilot. The LS clutch will bolt on a big SBC/BBC 168 tooth flywheel, but not the 153 tooth. Just use the SBC clutch that matches your flywheel though. No need to change style

[@tinkeringtimmermans5249]

Awesome video, lot of useful information. I am curious if this also applies to gen 4 ls stuff? I have a 2014 2500hd with the 6.0 (l96), I would love to put a zf6 in there when the 6l90 goes. It’s a bummer I can’t use the tcase that’s in there. But a earlier ls flywheel and pilot bearing would work?

As far as I know, yes. The gen 4 car engines still used manual transmissions, and a tr6060 will fit a gen 3.

Hey I just stumbled across this video and it was super helpful. I do have a few questions though. I currently have a 1996 6.5l td bolted to a sm465 to a np205. The starter is interfering with the flywheel. What flywheel should I be using with this setup? Also I am interested in swapping in a nv4500 at some point and I wanted to know how much work that would be to convert? Do I need any adapter plates? Thanks!

[@GEARHEADdezign]

I would assume you want to use the flywheel that's original to the engine. Those 6.5s got the nv4500 from the factory, and it should be able to use the same clutch as sm465.

[@GEARHEADdezign]

Depending on the year of your sm465, it might be basically a direct swap. Mine came out of an early gmt400 and the measurements appear to be a direct swap with a 90s nv4500. Earlier square body 465s had the shifter further forward, and I'm not sure about the tcase adapter measurements

[@GEARHEADdezign]

You can tell if it's a square or gmt400 trans by the shift cover. Squares had a cast iron cover with the shifter mostly centered. Gmt400s have an alum cover with the shifter offset to the rear

[@lifeonlimiter4519]

So what about a nv3500 behind a duramax?? Or t56 for that matter?? Input shaft bearing same size as the zf6??

[@GEARHEADdezign]

That I'm not sure. The bell housing pattern is the same. I'm guessing you mean the pilot bearing, not the input shaft bearing. Could prob check Rockauto and see if it's the same

[@GEARHEADdezign]

Neither would be a great match for lots of diesel torque though

If i do need a different bell housing, i have a bell housing off a 65 C20 327 with a 4 speed. Do you think that might work? I honestly want to mate them together as cheap as possible. Would you be able to guide me as to what i'll need as far as the flywheel, clutch, pressure plate, slave cylinder, and bearings?? Thank you in advance. Btw the 5.3 and t5 are planning to go into that 65 chevy of mine lol

[@GEARHEADdezign]

The bell housing pattern is fine, but it's the flywheel that's the issue. I think the t5 bell is set up for smaller 153 tooth flywheel, where LS needs the bigger 168 tooth style. BBC always came with the 168, but some SBC trucks etc did get the 168 also. So try out the c20 one. Use a 2002 4.8 flywheel and a 2002 Camaro clutch. If the c20 bell doesn't fit, grab a BBC bell.

Cool info… I have a question… I have 1965 Chevy pick up truck with 327 motor. Original came with manual transmission Years ago I made it automatic now I want to go back to manual and I was thinking if it’s possible to put one of those six speed Camaro transmissions. Tanks…

[@GEARHEADdezign]

Yup. There's a couple ways to do it. 1 - LS1 style with adapter plate for SBC bell housing. 2 - LT1 style with lt1 bell, clutch and conversion flywheel for 2pc rear main seal #2 is the setup in my Camaro

Ive got a 79 chevy c10 with an 80’s 350 and a 350 turbo trans.. what would i need to do to put in a nv 3500?

[@GEARHEADdezign]

Is it a 87+ 1pc rear main seal engine or earlier 2pc? You'll have to get a firework to match whichever one you have. Then order a clutch for a 94 k1500 and probably a new driveshaft.

[@DonnaBuchanan-dv1ef]

It looks like I got a sm465 5 speed transmission with the fork What all do I need to put behind a 5.3 ls ? Thanks

4.8 flywheel and clutch, with master and slave that match the trans

I hv a question iam about 2 do a engine & tranny swap into a 96 s-10 iam putting a 2000 ls1 and t56 tranny in my questin is will my tans shifter come out in the same hole as my 2.2 four banger and the i belive is the nv 1500 tranny my name is steve.

[@GEARHEADdezign]

The nv1500 shifter comes out the same place as the s10 nv3500. I have measurements in the video, but I'm quite sure the t56 is still rearward of the s10 hole. I have the opposite issue with the sm465 going in mine, where the shifter will be forward of the hole

[@ronnelson7828]

Some 10 years ago I lucked out and found a low miles '95 Formula TA with the LT1 and T56 in a local pull it yard. I picked up the trans, flywheel, and clutch dirt cheap, but it's still in the parts bin waiting for the answer...I refuse to use the pull clutch and want to use an internal hydraulic throwout. Are aftermarket parts the solution? Edit: This would used with either a 2 piece or 1 piece rear seal, I've got both. The LT1 flywheel I believe is the same balance as a Vortec 5.7 1996-2002.

[@GEARHEADdezign]

Everything will bolt up factory with a 1pc rear main flywheel and the pull clutch. To convert to push clutch you'll need ls1 input shaft, front plate and old BBC bell housing and 4 bolt adapter

[@GEARHEADdezign]

FWIW, I'm using the pull clutch on my Camaro and it works fine. I have zero issues with it.

[@patrickmchose7472]

Try looking at Novak Conversions. They pull off all kinds of crazy stuff.

[@whistlinn7.3]

Wouldnt the zf6 out of a 7.3 powerstroke be the same as a 8.1?

[@GEARHEADdezign]

Similar, but no. The GM ones (8.1 and dmax) have no external fluid cooler and the bell housing pattern is different. Not sure about input output shaft splines etc either.

[@David-zc9xl]

I'm planning to get v6 standard silverado, single cab and put that 5.3 in it. I've heard thevtrans will hold. Should I put a dual disc in it. Got any info I may need ?

[@GEARHEADdezign]

Yeah the NV will bolt right up with 4.8 clutch and flywheel. If you want to make huge power that requires a dual disc, I'd find a different transmission. But a typical 5.3 will be fine if you don't hammer on it too bad.

[@David-zc9xl]

@GEARHEADdezign right on thanks bud. I mentioned the dual disc since I driver a nv5600 cummins. But it's diesel so the torque is different for sure

[@JoseGonzalez-pz9ug]

So I want to swap my t5 transmission to the lt1 t56 I know you saying they both use hydraulic put what did you mean by the pull style clutch and would I have to change my clutch and flywheel. Also Would I also have to change my master and slave clutch cylinder or would they be compatible

[@GEARHEADdezign]

Your master is probably fine and maybe the slave...but def have to change clutch. Maybe flywheel too. Look up on Rockauto if flywheel is the same for TPI and lt1

[@GEARHEADdezign]

I just checked, flywheel is different

[@tombrown879]

Hello. Can the 12in SBC clutch and Flywheel fit inside of the nv3500 bellhousing?

I really need some help. I'm looking to put a 5 or 6 speed manual transmission in a 1999 chevy suburban k1500. I don't even know where to start can you help thanks.

[@GEARHEADdezign]

I did the same in my 94 k1500 z71, auto to manual. Nv3500 or Nv4500 would be the way to go. The nv4500 is heavier duty but the nv3500 shifts smoother...so it's up to you. Either way you'll need a 32 spline transfer case. They came with all manuals and also 3/4 and 1 ton autos of the same generation.

Hey man great video but I don’t e a question for you, that nv3500 looks to be a great option for my nova but what would be the best option for a hydraulic throw out bearing if I could find that transmission

[@GEARHEADdezign]

Watch out for bell housing to shifter distance on the nv3500. If you can find the s10 version instead of the Silverado one it will move the shifter back a bit.

[@GEARHEADdezign]

They come factory with the hydraulic release bearing stock, so just use that. Same style as LS t56 trans.

[@justinstewart1499]

That makes sense… what about the the speed sensor? How to make that retrofit?

[@GEARHEADdezign]

@@justinstewart1499 you'd have to do an elec speedo. Like in my Beretta I'm using the factory elec speedo and just changing the tune to calibrate it

Any idea how much bigger the NV4500 is compared to the NV3500? Im wanting to swap in a NV4500 with a 5.3 in my 92 Sonoma.

[@GEARHEADdezign]

Size-wise they're basically identical. But the nv4500 only came in the full size truck config with the shifter further forward...like 6-8". And they all will have 32 spline 6 bolt transfer case, not the 27 5 bolt like s10

[@DittoBlast]

@@GEARHEADdezign Yeah if I need to go with a new transfer case I will. Sounds like the only issue might be the shifter location.

wow ..excellent video with almost all info i was looking for, except ring size ? how many teeth to use with LS starter? can i use flywheel off '81 250ci inline 6, w/ HD pressure plate , that truck pilot bearing do you know part #? will the input shaft on Borg-Warner 5sp.be long enough or does somebody make longer input shaft that will fit B/W 5sp. do you know? also is it still possible to drill and tap flywheels for any pressure plate application ...👍🛻

[@GEARHEADdezign]

The LS flywheels are 168 tooth. I know a T5 input shaft works. I wouldn't drill and tap a flywheel when there's easy, cheap off the shelf parts available. Especially with the RPM and inertia involved. I do some sketchy stuff, but not that🤣

[@GEARHEADdezign]

For light duty gear banging, and keeping 4WD, go with nv3500. T56 can work, but the gearing is really tall for a truck and they're pricey, and only 2wd.

[@cotycaudle427]

So do you think there is a possibility of the lt1 t56 working behind an ls with the truck pilot bearing?

[@GEARHEADdezign]

I was hoping for exactly that! However, the problem is the bell housing. The LT1 bell won't fit the 12" LS clutch. And the LS bell is longer, and the LT input is too short, even for the truck pilot.

[@cotycaudle427]

What if you use the truck flywheel and clutch?

[@GEARHEADdezign]

@@cotycaudle427 Truck flywheel would get the clutch splines better aligned with input shaft, and it would have to be a 26 spline Camaro disc. But the input pilot won't reach even the truck pilot bearing. Maybe if you had a custom long pilot bearing made?

I know the zf6 behind 8.1 and dmax is the same, so that means the 465 should swap easy. I don't know about the 2wd to 4wd swap, but 4wd trans are a dime a dozen
