My A833 Non OD is difficult to shift into second gear at any speed much above idle. I rebuilt it and put in new 3rd and 4th gears, also new brass synchros on all 4 gears. Second gear isn't the greatest but isn't that bad I don't think, but I am no expert. I plan on replacing it now that I have it apart again, just for peace of mind. What else in there could cause a problem shifting into second? All other gears shift fine, up or down shifting. I have some pictures I will be posting shortly.
