Been real busy last couple of weeks

Well I just adjusted my signature to reflect my current line up.  Sold most of my 2 parts trucks to a father/son duo that is building a couple after initially coming to buy the blue tweed seat from the 87 I had here on the classifieds.  Long story today I landed a decent 85 C-10 with a topper that is perfect to turn my 17 year old loose in after I fix a few things on it. The transmission is missing 2nd gear, never had one do that before.  I think it is a TH350C but have not crawled under to verify.  Anyway I am real happy with my find and even more excited that I can make my 86 C-10 for me as originally intended.  Pictures to come...

Nice going on the liquidation.  Question for ya, what 4 speed are you running that has OD?

The option code is MY6 which is a New Process A833 geared almost identical to the 700R4.  First gear is 3.06 while 4th is overdrive at .71

must be hard to find, all I can locate are mopar a833.  I was thinking that would make a perfect intermediate trans for my dream truck.

Do you have any more info on that NP A833

That's really cool. There's no better truck than these to have as your first.

http://www.motivegear.com/tech_info/tranny_guide/tranny_guide.html  mentions it that it was available in the 81-86 models GM trucks  I used to have additional info however the pages saved in my bookmarks are not valid any longer

http://www.slantsix.org/articles/4-speeds/ODA833fourspeed1.htm on the transmissions themselves.  Basically it is the GM version identical in size to the 3 speed Muncie but most have a different bolt pattern to the bell housing which most of the 81 and newer aluminum bell housings have the dual sets of holes for the drivers side.  I've managed to collect 3 but only 2 have shifters...

Here is a couple of pictures of the beast

My oldest started out in a red 86 GMC 1500 as his first but much rougher shape than the 85 is.  Nice to have a shed full of parts to keep it going should something happen is a plus too...

The chevy version of the A833 is a rare one, good score!

     I never knew about the A833 that would be a great transmission for a 4 speed.  Is there an outside appearance that is different between a A833 and say a Sm465 ?

[frogman68]

The A833 was used in 81 to 85 C/K 10's mostly diesels I have a 84 K10 with it
I cant wait to see pics of the 86

     So if you found a diesel k10 4 speed manual, more than likely it would be the A833 ?

[slammed79]

Its a possibility Bake. There wasn't a ton of them ordered

In a bookmarked link I had that no longer is valid out of all the standard transmissions sold 0.6% were the MY6 optioned 4 speed OD.  Any owners manual 81-86 shows the transmission in it.
