Any help on identifying the transmission from the attached picture of the tag on top of the housing would be appreciated. I bought it as a 5 speed that came from a Chevy S10 with a 4.3 engine. I've looked and googled and came up empty with any definite information on what the transmission was used with and what the gear ratios might be. I also tried searching the post on here, but "Muncie" only seems to find 4 speed stuff and when you add "5 speed" it only muddys the search more. Thanks in advance for any help you can give.
That's because the only "real" Muncie is a four speed! Who's bar code is that? May have better luck if you posted a photo of the transmission.
Muncie is a GM assembly plant although it’s come to be a byword for one type of box they made there. The part number is 15015873. Eg https://www.ebay.com/itm/292322862930 https://www.wholesalegmpartsonline.com/products/TRANSMISSION-Manual-5-Speed/2699695/15015873.html
That's probably a NV3500 5 speed transmission. I believe Muncie plant is a supplier. I have one at home, has integral bellhousing and came from a 2000 S10 Extreme.
This is correct. '96-'99 NV-1500. Does your transmission's integral bellhousing look like this from the front?:
Yep that’s what mine looks like. I took a chance on it, but looks like it’s not what I need to go behind my 350. Thanks
Your first post said that it came off a S-10 with a 4.3.....the 4.3 is not a 60° V-6. Anything that bolted to a 90° V-6 4.3 will bolt to an SBC. I believe that it is the NV-3500. Post a picture of the bellhousing face.
Correct, the NV3500 is what was used behind 4.3 V6 (and 5.7 V8 in other trucks/vans). The trans in OP's is the NV1500, used behind the 4 cyl S-10. Both 3500 and 1500 are integral bellhousing; the 3500 having the std chevy V8 bellhousing pattern. Both do not have the traditional separate bellhousing and trans like the old school Muncie 4 speeds, or 3 speeds. The NVs also have hydraulic clutch, not traditional clutch fork for throwout bearing.
I think the NV-3500 would be a good choice, especially as S-10 T5s are getting more difficult to find. The NV-3500 is stronger than a non-WC T5, and bolts right up to the traditional SBC block, too. https://www.dieselhub.com/trans/nv3500.html If you Google search the code or part number on the sticker/label, you should get a fairly quick idea of what the trans is from and/or fits behind.
FWIW, GM used the NV3500 behind the Vortec 350 V8s in full size trucks and vans. Also behind the 4.3 V6. So should hold up fine with a reasonable driving technique and limited street tire traction.
