4 speed manual overdrive?

I have a 1982 chevy 6.2l. When I got the truck it had the original transmission in the box because the 208 transfercase blew up. It now has a sm465 with a np205 transfercase. My concern is was the new process manual an OD manual. And how can I find out? I have the casting numbers. The original transmission casting number is 465452
5263

The top plate (cast iron) has Somthing like 0D
3901131


The one thats in the truck now with the 205 transfercase casting number is 465452
0348.

I looked up my vins and it says the trucks got 373 gearing. How would that do without OD?

How do I know if my 4 speed has OD?

Are you asking if the New process manual trans was an OD trans? If so yes. NP833 I think it's the only New process tranny they put in full size trucks. Originally sold to Chrysler later sold to GM as well.

Without Overdrive 3.73 gears are doing around 2800RPM @ 60mph or so. Google RPM calculator and it will give you a few.

That's right and if it has reverse beside 1st like a volkswagon it's definitly NP833.
It also comes with a mutha lovin' hurst shifter. Kinda hard to miss, super bad ass

the A833 was a chrysler transmission from the beginning. put behind 440's and 340s and all the big guns except the hemi. was a 4 speed without overdrive untill newprocess got it. then they changed 3rd gear to overdrive and flipped the shifter arm on the case to make stuff line up. thats why 2nd to 3rd is such a jump.

Really? well tha's neat. I always found the leap from 2nd to 3rd to be pretty good. If i was highway driving I wouldn't shift to 3rd until about 70kph and the truck was just howling. on rare occasions I'd skip 2nd alltogether if I could get the RPMs in 1st high enough (like redlined)

so even though it say on the casting number 465 452 its not a sm465? What part is different in the case? The bottom set of gears or the top set inside the case?

Is the linkag on the side? I believe the sm465 ha the linkage on top and the NP833 has linkage on the side. Where's reverse? to the left of 1st is Np833
