I have a A-833 4 speed in my Cuda. Here is the problem(s) I have been having.
1. Shifts into Reverse really hard
2. Grinds shifting into 3rd & 4th under acceleration.
3. Pops out of 2nd under deceleration.
Most of these problems started after the 3rd-4th shifter fork pin broke off. I bought a new one and installed in the car.
Question is could these problems be related to the shifter fork being bent when the tranny was rebuilt and since there is a new fork in now it needs adjusted or does the entire tranny need rebuilt again?
thanks

I would start by adjusting the shifter, some might comment on synchro issues but reverse has no synchro and you are having issues in multiple gears.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

I wondered if the shift fork pin might have been cracked when it was rebuilt as it broke not too long after it was rebuilt. No I didn't know about having to adjust it after I installed the new shift fork. What is the process to adjust it? thanks guys

2nd gear used to pop out on mine as well. I put a new 2nd gear in it and it solved the problem. Also, mine used to shift hard. Make sure the transmission tight against the bell housing. The bolts have a tendency to loosen. Put some thread lock on them and that should solve your problem.

Thanks Duster, I'll check that out as well. I thought someone said something about having to adjust the interlock mechanism that is on the cover housing. I'm guessing that is the interlock that keeps you from shifting to reverse while it is still in another gear? 
No the interlock on the side cover itself has no adjustement and the design of the shifter is what keeps it out of reverse while trying to shift another gear.
As far as a bent or cracked pin , if that was the brass shift fork I have broken 2 of them under heavy shifting and a misadjusted shifter can contribute to that.
To adjust first, put the trans in neutral then remove the shift levers off the transmission itself. On the shifter there is a place to put a 1/4" round pin, a drill bit will work , slide it thru the outside notch, all the shift levers and into the notch on the other seide of the shifter box, this is neutral. Now adjust the shift rods as necessary so they easily slip back onto the trans levers.

Thanks John, I will give it a try. I adjusted the shifter when I installed but maybe it needs adjusted again now that I replaced the BRONZE shifter fork. Yes it was bronze.
thanks,
Mike

I was thinking also that the reason it is shifting hard from 3rd to 4th, is that your 3-4 synchro may be bad.

3.If it pops out of gear the "dog" teeth on the gear are worn. Replace the gear.
Very true and they are not cheap. Jamie inspected all of my internals in my box and he noticed that the teeth were worn and indicated that it may pop out of gear. A new gear went in.

The problem you're having with reverse could also be the side cover alignment. I'm having trouble remembering this exactly, but I think when the side cover is installed, you're supposed to verify that the reverse fork arm and the 1-2 fork arm have a specific clearance between them when in reverse. What I mean is that it's definitely possible for the two fork arms (inside the trans) to rub each other making it hard to get in reverse if the clearance isn't right. If you had a damaged fork, maybe the fork arms are bent too.
The brass forks were known to break, well at least I have broken 2, I ASSuME it was part of the reason they changed them to iron.
But yes , loosen the side cover bolts a touch and tap the cover up.
But I'd look at clutch adjustment also.

My 69 RR used to jump out of 3rd on deceleration back in the 70's and it turned out to be a bad rear main case bearing. After I changed the bearing it never happened again.
