I'm going after it with a basic rebuild kit and a set of lockers for the syncros which is what I think are my problem staying in 2nd gear. Is there anything that I should keep in mind before tearing into this thing? Its for a 70 383 E body.
Check the synchro teeth real close. If they are rounded off instead of sharp edges, it could be cause for popping out of gear or hard shifting under power
Since you're already in there, (As Dennis put it) a new countershaft is cheap insurance. I got mine from Brewers for $25. 3/4" Electrical Conduit is the perfect diameter for a dummy shaft when you remove the countershaft. (I got that tip from a board member) I wouldn't worry about using it when removing the countershaft. Everything will fall apart, but the manual tells you exactly how to put it back together. Once you have the gear out, trim the conduit to length making sure that it also locates the thrust washers.
If you have a NAPA, I found a product called "Transmission Assembly GOO". It's a green grease product that is sticky and provides lubrication on startup. The sticky part is good when you have to put the roller bearings in place.
1/2" threaded rod, nuts, washers and a socket can be substituted for the tool to press the reverse idler shaft out. You'll need to do this to replace the reverse shifter O-ring (which I would recommend).

More 833 Q's.....
....So I have a 66 A body 833, cracked input shaft bearing retainer. The MP reissue is on nation wide back order, with no promise date. Can I pull the gears out , still on the tailshaft, and install them in the OD case, using the OD front bearing and retainer? If the ID of the bearing is the same on all 23spline input shafts, this should work, right?
If the front bearing retainer on the OD type has the same bolt pattern and appears the same facing the trans, oil return passages etc then it should work on the old 66 trans, Id do that first. What you could do then is have the OD retainer cut down on a metal lathe to the "right" size compared to your old broken piece, any good fabricating shop can do this that has a metal lathe and somebody who is competent. Another option is to call an outfit like brewers in OH and buy a good used piece of the type that is broken.
i just weld mine up then they are stronger than ever.
I do know that the bolt pattern on the OD front retainer is way bigger than the older A-body piece. so that wont work.I dont know about swapping the whole mess into the OD case. I think that the front bearing retainer on the A-230 three speed tranny is the same as the one used on the A-body 833...might give it a try. it should be fairly easy to find one.
BTT......Dennis? Welding them is OK, huh? I thought about that and wondered about strength, warppage issues. Might have to try welding, can't possibly screw it up any worse than it is now.
I think I understand what you are trying to do. The OD trans uses the #308 input shaft like the HEMI's and the #307's in the back. The other 833's use a # 307 for the front and rear main shaft bearings. The one diffrence in the cases is that the OD trans use a softplug in the front of the trans to seal the counter shaft bore, the others dont. The outside diameter of the #308 front bearing is larger and wont fit the hole in your bellhousing and the #307 is to small to use in the OD case. So the OD brearing retainer wont go in the hole on your bellhousing
jo , call liberty , they have a billet one , never have to worry about breaking it again .
The small retainer 833's use the same retainer as the A 230's, and car A 745's. They really aren't that difficult to find used if you know where to look. You can use the OD case and bearing retainer, along with the bearing, but you'll also need the accompanying bellhousing, or swap on a 70-74 big block retainer for some applications. Only the short shaft OD's used the small rear bearing. ALL long shaft 833's used the 308SG8 rear bearing from 1970 on up. Unfortunately, you will also need to re-use the old mainshaft/tailshaft housing, as the 66-67 A bodies used the very small 207 rear bearing, and 904 type slip yoke, unless you find a 30 spline OD/DD tailhousing, and a corresponding 30 spline 68-76 non OD mainshaft. (Entirely bypassing the 66-67 stuff) Dennis
Ok, I have three OD transmissions, 2 of them are A or F body, one is truck. One of the A body ones has the larger output spline, not sure on the other, I'll have to dig it up and find out.
jo , do you have an OD bellhousing to go with those transmissions ???
liberty's number is ...313 278 4040
Brewer's Performance sells them for 89 a piece. Much nicer than the factory one. I just bought one for my car about a month ago.
