Check shift linkage for adjustment: put shifter and trans in neutral disconnect rods from trans and line up all 3 shift gates on shifter, there should be a hole in the gates. I use an allen wrench to line them up or anything to line them up. attach rods to trans or adjust swivels to line up to shift levers on trans. That should help if not possibly internal, maybe a bad synchro. I had the same problem with my Cuda but it was a bad shifter.

Did you align/adjust the shifter rods when you installed it? Years ago I had problems with not always being able to shift into a certain gear when I was driving the car (can't remember which one). Someone told me that I had to align and adjust the shifter rods. Once I did that the trans shifted much better.
Not sure if this is your problem or not but if you have not adjusted the rods I would suggest doing that to see if it clears things up.

The transmission was purchased from a well known mopar transmission business as a complete kit to convert to a 4 speed, I don't want to mention there name yet in case its my error that the trans does not shift right but they are well known . I used the gear oil they sent, it was hypoid sae 85w90
I only drove the car about 5 miles total since the install. I did adjust the shifter with the pin in the levers and the shifter its self does not jamb up. I was able to speed shift it at 4000 rpm with no jambing but it did not go in to 3rd very well I felt it go part way in then sort of clunk as I left the clutch out and went the rest of the way. Its a new hurst competition plus shifter. I didn't set the shifter stops on the shifter housing yet, I thought I would wait until it all was working. It dosent matter if I am shifting up or down shifting, 3rd still is hard to shift. I have been running a 4 speed in my dart for over 20 years now and always set it all up myself , I have had the shifter jamb in it before from the rods being out of alignment but this car dosent jamb between gears, it just does not want to go in. Is it possible that it just needs warmed up and broke in?

OK, it sounds like this isn't your first rodeo Did you set the air gap on the clutch?, what type of clutch?, do you have any reverse gear clash/grind during engagement?...is this condition present in the: 2nd to 3rd or 4th to 3rd shift or both?

Reverse does not grind, all of the other gearz work fine. Actually none of the gears grind . 3rd just will not always go in all of the way. The linkage is all new, and the clutch is adjusted right. It jams in the 4 to 3 and the 2 to 3 shift. It goes in part way but will not fully engage until I let the clutch out , then it pops in
The "condition" you've explained can have several causes:
1 Improper clutch adjustment, you've supplied no specs/details on your clutch/assy
2 Improper cross over adjustment, basically setting up the shifter properly, and stops if so equipped (I think this is your issue IMO, your over shifting the box, thus the gear hang up) If the above items are 100% on the money...
then: 3 Synchronizer clutch sleeve is bad...or
4 Syncro Spring Installed improperly...or
5 broken/worn Syncro stop rings....
I'd start with properly setting up the shifter again, making sure all components are 150% as well as my adjustments, and I would set the shift stops up as well, as they are critical to limiting the throws in the shift box (a critical function you still haven't performed)...I would never have driven the vehicle until these basic procedures have been established IMO

thought I would let you know how this worked out. I drove the car for probably 45 miles and it started working fine. I guess it just needed broke in. never had that happen
Thanks for the update. Wish everybody would do that.

Appears all is well. Some 30 years ago I replaced the 4 speed in my 71 Vette with a Doug Nash 5 speed,,,still have the car, owned since 72.
Upon driving however, it was extremely hard to shift, particularly when not warmed up. Did not improve much with break in. Replaced 90 weight with Red line synthetic. Was now like a hot knife thru warm butter Dragged race for a few years when our local Fremont strip was still in business. Had uncounted full throttle shifts at 6,500 rpm, transmission still performs flawlessly. Amzoil and Mobil 1 among others offer excellent synthetic gear oils that could make your shifting even more pleasant.
Did replace L-88 clutch and flywheel a couple years ago as it was becoming too much of a leg buster for me,,,,,,kinda like my 70 challenger is now,,,likely another future project.

The A833 is finicky in regards to synthetic gearoil.
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.
