Postby glane on Tue Feb 27, 2007 8:07 pm

New Process ? 4-speed

Postby glane on Fri Mar 09, 2007 5:42 pm

it looks like the new process A833
it has a 10 bolt cover
the case is aluminum
the only thing different from
the pic is the tail shaft is shorter
and by checking first gear
by spinning it, it is 3 to 1
the only numbers i can find on it
is C-15475 and then the NP stamp
its total length is the same as my
3-speed saginaw

thanks a lot for the info!

I ran a NP A-833 OD in my 85 Regal for two years before switching to a ST-10. No granny gear. But it does indeed have a 3.00-1 first gear that launched great. OD was nice on trips too with my 3.90 rear. Its not quite a bolt in. The input shaft cover will have to be machined down if your using a stick G body bell. You'll need socket-headed capscrews to fasten it for clearance. I had to fab my shifter bracket and rods to put the shifter in the G body position, which is more forward on the trans than an old A body. Good luck!

this transmission is a 4 speed with overdrive, they were used in chevy and gmc trucks alond with some dode vehicles. they are very sought after from the street rodders. it is a tough transmission and will take some harsh punishment. i currently have the same transmission out of my truck and have it listed on ebay for $350 buy it now. If you call kurt zeller at just chevy trucks he will get you the info you ned, here are the phone numbers

Wow, those A 833s are valued quite differently around here. Usually they are 'round $100. Most I ever paid was $90. The aluminum case and really tiny Overdrive gear are weak points. A conversation with Passon Performance recommended that they are not good to use in high performance applications. They are simply cheap OD units.
