A833 is a only a four speed trans.I have one behind a 6.2,it's a nice combo.

Your right. I jumped the gun. I gotta find one, then I'll remember!

A833 has been on Craig's list Louisville, KY for the past several months. Search "new process". Pics are limited in ad, I would ask for more. I think it is in IN or OH.

Or see if you could do a t5 swap on it.

Any gm tranny will because it has a sbc bell housing. Could use a nv3500 if you won't beat on it hard or if you will a t5 will be good. Also a nv4500 would be the in between transmission. Many options, just depends on how deep your pockets are!!

Since this is a truck, If you went T5 you'd be best to find a WC (world class) T5 over the standard T5 for the reasons listed in this blog;

nv3500 and nv4500 can it the 88-98 trucks

-GM T5 will bolt in with no significant clutch changes but is 2wd only. World class T5 has a 300ft lb torque (not HP) limit. No low gear for starting with a heavy load. 4 speed with OD 5th.
-GM NV3500 is good to 300ft lb of torque (not HP). 4wd and 2wd versions. GM Corporate engine to bellhousing pattern. It requires the install of a hydraulic clutch master cylinder as you can not remove the bellhousing. No low gear for starting with a heavy load. 4 speed with OD 5th.
-GM MY6 Aluminum New Process A833 is a rare beast. 2WD only.Side mount Hurst shifter similar to the GM Saginaw Cast Iron 3 & 4 speed and Muncie car transmissions. Chrysler put the Mopar version behind the 1960's Hemi motors. 3 speed with OD 4th.
-GM NV4500 Is expensive. It's a big heavy beast. It comes in 4x4 & 2wd versions. 4WD will bolt directly to a RH drop 32 spline NP241 or NP208. The NP205 will require an adapter and extensive work. It requires an adapter bellhousing or hydraulic clutch your choice. Has a known 5th gear issue that requires mainshaft re-work. Low gear for heavy loads so is effectively a 3 speed with OD 5th and LOW 1st.
-GM ZF S650 6 speed Expensive and hard to find.

You can get a brand new NV3500 for $2000 but if you put a bunch of horsepower to one you will snap the bellhousing off.

The A833 was available in 2 or 4wd versions in GM trucks.My 82 is a K25, also have a 85K15 parts truck with one.It too has a fairly high first gear for starting out with a heavy load.I can throw the T case into low to get rolling though...

If you still have the SPID in one of those trucks... What's the RPO for the 4x4 version? I believe MY6 is 2wd only.

I had a late 80's D150 Dodge with the A833 OD. It would've been a pig to get it rolling without the torque of the slant 6.

I will check tonite when I'm back home and see if they are still in there.

MY6 is A833 whether 2 or 4wd.

THese are NOT the same as the Hemi boxes. Most are the lighter weight and weaker aluminum case (supposedly some 4wd's still are iron) and the gear flip means 4th gear gets a tremendous torque load.

If you do get one be sure to get the shifter (unique to that trans only and no aftemarket without modding a Mopar one, and different 2wd to 4wd), and realize the 2wd and 4wd use different output shafts, and the bell housings can be manual or hydraulic. My collection includes a 2wd mech clutch and a 4wd hydro clutch. There also are 2 different trans to bell patterns, one is the standard GM and one is Chrysler.

Weak point is the front retainer leaks and the wear of the idler shaft in the case (no bushing from factory).

It's torque that breaks stuff. 300hp at 6,000 RPMs isn't going to be a problem. 300HP at 2,000 is another story. Look at the torque curves. If they exceed 300 then you can't use a tranny rated for 300 max.

You'll note the lower two bolt holes were not damaged. This tells me that there were 4 bolts not 6 bolts installed in that bellhousing. If you don't put all the fasteners in place you should expect damage like that. I've blown away a TH350 that way. For that same reason.
I've also broken up the bellhousing up on a 4wd TH700R4 by breaking the transfer case mount loose without the engine to bellhousing braces and transfer case to bellhousing brace installed. I would guess the 4wd NV3500 is supposed to have similar braces to spread the load out from the bellhousing.

A serious downside to the automatics and the NV3500 transmissions are the integrated bellhousing that can't be replaced.

I've bought good used NV3500 for less than $400 in decent working order. No way I'd buy one new.

The transmission pictured lost all 6 bolts the picture is just bad.When you put a lot of power on them the bearings either wallow out from shaft deflection or the bellhousing breaks off.
In California or on E-Bay they run $900 plus a good core.The housing all by itself runs $600+ and then you need a $300 kit to put it together if your parts are good.
None of the early ones are any good at all as the front bearing goes out and takes the housing with it.\
I've tried a couple of the $700 wrecking yard versions and if your young and like working on them you might find something that will work.
New in the crate it comes with all the sensors the shift tower and filled with fluid.

The "early ones" you are talking about are probably the 1988-1992 HM290, MG290, & 5LM60. Buyer beware. They look like the NV3500 and many folks will call them an NV3500... they are not. What they are is scrap metal.

Use gearboxes in thier intended Torque class and they hold up just fine. Exceed it? Kaboom (Edgar K.B. Montrose)
My stepdad put 384k hard logging miles on a 4.3L K1500 with a NV3500. A branch through the oil pan killed it. The tranny wasn't making noises or giving him grief.
For a Stock emissions era 350 @ 200hp & 250ft lb with stock size tires, that you NEVER intend to change, the T5 or NV3500 will hold up just fine. Bump it up with a cam or exhaust or better intake or all of the above... You get the picture.

The World Class T5 and the NV3500 are in the same max torque class. If you're coming close to exceeding the torque limits of a gearbox, or you eventually will, you should step up to the next one. That's why I prominently posted the max torques. 300 ft lb is the limit for both of those boxes. If you tow, you run a motor with @280 ft lb, or you have plans to upgrade the motor at all... I would seriously consider using something other than a NV3500 or a T5.

Keith Seymore has one in his 87, which should have been the last year. As far as I know they were not offered in the GMT400's which started in 1988, or in 3/4 tons or behind 350's or big blocks. 4.3's, 305's and 6.2 diesels which have the same factory power output as a 305. were the limit for use.

Good morning everyone!!!! I have a WC 5 speed and I am restoring my 72 c-10 with the factory 350 and I am thinking about putting this 5 speed in and not the 3 speed that was in there from the factory. Can anyone tell me where would be a good place to take my 5 speed to and let them rebuild it. I know some people say they are transmission men but I need someone that has a good reputation. Thanks

[LynnJr]

I have the MG5 pictured above I will give away with the shift tower if someone wants to pay the frieght.If you can weld the bellhousing back together the tranny had no issues otherwise.
