70 A833 Lost 3rd & 4th gears need help

[Bigmanjbmopar]

Looks like 3rd and 4th is not engaging for some reason its like free play in neutral. Any ideas on what the issue could be before we take it out? The rod is connected and we can see it moving on the trans but it's free as a bird

Sounds like your shifting fork broke off. It's made of brass or some other soft material. Remove the side cover and it can be replaced without tranny removal

I just repaired one with that problem and one of the three keys for 3rd-4th in the synchronizer broke.

Can it be fixed in the car?

Yes but you need to check for small pieces in th gear oil

Take the side cover off while in the car - if it is broken shift fork it can be done in the car.
Broken synchroniser - no you would need to disassemble the gearbox.

Agree with the above

Likely a shifting fork. I would throughly check the detent mechanism on the cover as well, if the fork looks good. I have seen a very few break the shaft where it comes through the cover. Easy check and fix either way. As others have mentioned no R&R needed.

Went through the same thing last spring. Replaced the 3/4 synchro and shift fork. Also a good idea to get a gasket kit.
Brewers Performance had the parts. Yes the transmission needs to be removed from the car.
